PRINCIPAL Profile

The Principal (校长, Kōchō?) Voiced by: Kenichi Ogata

The unnamed principal of Sainan High is well-known throughout campus as a pervert. He will enroll any girls into the school body so as to ogle and grope them without hesitation (though, according to him, they have to be "cute girls"). This groping is not limited only to Sainan High, but in public, as well. A common gag involves the Principal spontaneously shedding his clothes and chasing after a girl he becomes smitten with, which inevitably results in him beaing beaten to a pulp. Once, Run purposefully causes herself to change into Ren to get the principal to leave her be; upon seeing Ren, the principal thinks briefly, then continues to chase him (stating "This is okay too").

Throughout the series, the principal has survived many severe injuries and attacks. Some of these include burning, (by Kirisaki Kyoko) beaten up, and on one occasion, almost eaten by a crocodile in the Amazon.

GID LUCION DEVILUKE Profile

Gid Lucion Deviluke (ギド・ルシオン・デビルーク, Gido Rushion Debirūku?) Voiced by: Hidetoshi Nakamura

The King of Deviluke and Emperor of the known universe, Gid is the father of Lala, Nana, and Momo. Despite his near omnipotent power, he has the physical appearance of a child, looking slightly devilish, with shark-like teeth, spiky black hair, and the characteristic Devilukean tail. While his daughters' tails end in spades, his appears as a wicked looking trident. Gid's personality borders juvenile delinquency and (extreme) perversion, going as far as to use his child like appearance to get close to pretty girls, thus Lala claims the only reason he wants her to get married is so he can step down as king and be free to pursue his perverted hobbies. Lala states his current appearance is due to him using too much power during the "Galaxy Unification Wars", which desized his body, following his conquest. However even in this form he is described to still be very powerful, stating he could destroy the Earth if he released it.

OSHIZU Profile

Oshizu Murasame (村雨静, Murasame Oshizu?) Voiced by: Mamiko Noto

The ghost of a girl who died in the old abandoned school building 400 years ago, Oshizu is sincere, kind, and very curious about the modern world, but has a severe fear of dogs, likened to Haruna's level of fear to the supernatural. When frightened, she can emit blasts of mental stress, blowing apart various objects and surroundings, but is also capable of manipulating others through sheer willpower. Since her meeting with Rito and the others, she begins exploring the world outside the old school building. Oshizu is aware of Haruna's crush on Rito by her ability to sense feelings while possessing another person and becomes very supportive towards cheering Haruna into confessing her feelings to him.

Oshizu "returns" to the living, after Ryouko creates a prosthetic body for her to inhabit, built with biological qualities (looking and feeling like an actual, human body). However, she occasionally "disconnects" during brief moments of excitement. She currently works as a nurse for Ryouko. In the anime, Oshizu is not given a new body and her presence is limited, while she has her body as she does in the manga for the OVA releases.

YAMI (Golden Darkness) Profile

Golden Darkness (金色の闇, Konjiki no Yami?) Voiced by: Misato Fukuen

A dispassionate, withdrawn assassin Golden Darkness is hired by one of Lala's arranged suitors, Lacospo (ラコスポ, Rakosupo?) to kill Rito, until she breaks the contract, noting the true nature behind her target. Golden Darkness came on a ship called Lunatique which is very quick (reaching a planet 30 million light-years away in 2 hours). Golden Darkness is currently staying on Earth, roaming around the city streets and Sainan High, with a motivation to continue her duty to assassinate Rito, although she has yet to accomplish this (hinting she only said this as an excuse to stay on Earth, which is then confirmed). Commonly referred as "Yami-chan", she spends her time reading books and magazines, while eating taiyaki (it is the only thing she eats on Earth since it is the first food offered by Rito, prior to spending a night at the Yuuki residence for a sukiyaki dinner). By her planet's (Kurosu) calculations, she is 24 years-old, despite having the appearance of an 11 year-old (albeit a rather mature one), although this is only mentioned in the anime and has a weakness towards anything slimy.

Like Lala, Golden Darkness' physical abilities are exponentially stronger than a human's. She carries a unique ability to turn her body parts into various objects through use of nano machines circulating her body, ranging from swords to dragon heads. Unfortunately, excessive use becomes a hazard to her health. She states she hates "ecchi" people, and does not hesitate to assault a person who looks at her in an obscene way. She has become close to Mikan Yuuki and seems to have developed a sense of protection for her, evident when she and Mikan switched bodies and the Principal attempted to grope her, to which she menacingly told him not to touch Mikan and delivered a savage beating. Though she always says she will kill Rito one day, it is doubtful she will ever do it. In fact, as of chapter 159, she seems to have begun to develop feelings for Rito. Instead of beating him and saying "I hate ecchi people" like she normally does, she blushes when Rito saw her in a swimsuit and stated "Don't look at me with those ecchi eyes". She even went as far as to go against something slimy to save Rito.

Recently, it is revealed that Golden Darkness's creator is also named Professor Tearju by the assassin Kuro.

She is based on the young girl from Black Cat, Eve, seeing how they both can turn any part of their bodies into a weapon. Also they're both voiced by Misato Fukuen in the anime.

RYOKO MIKADO Profile

Ryōko Mikado (御門 涼子, Mikado Ryōko?) Voiced by: Masako Joh

The provocative school doctor at Sainan High, Ryouko helps out other extraterrestrials on Earth in various manners, usually those dealing with medical care, though she does offer students a variety of her own concoctions. Formerly an operative for a shadowy, black market extraterrestrial organization bent on overthrowing Emperor Gid, she fled from her superiors to Earth in hopes of hiding her identity. Proof of her non-human origins are the elf-like ears hidden by her short hair, though it has yet been specified what her species is. Furthurmore, she seems to be smitten with Rito, shown when she once asked him to rub oil on her and didn't look surprised when Rito accidentally says "I love you" to her, Nana, Yui, and Run.

YUI KOTEGAWA Profile

Yui Kotegawa (古手川 唯, Kotegawa Yui?) Voiced by: Kaori Nazuka

An uptight, high-strung girl placed in Rito's class during the second year, Yui has little to no tolerance for anything she does not consider to be "acceptable behavior", ironically despite this seems to secretly desire for Rito to do them to her (where in the OVA 5 she states "you can only do naughty things to me"). Her haughty opinions, quick temper, and habit of speaking her mind often results in her vocally reprimanding classmates. Yui quickly grows annoyed and disgusted by eccentricities and bizarre actions, particularly with regards to Rito and Lala. Unfortunately, almost every encounter with Rito usually ends up with her embarrassed, naked or groped, and although though her nature prevents her from easing her behavior, she does slowly warm up to his usual antics. After Rito saves Yui from a group of delinquents, she develops feelings for Rito, although her inexperience with boys leaves her unable to understand her feelings and continually denies her feelings to herself. And when Rito usually asks what's wrong, she says the exact opposite of what she wants to say and then hurts him in some way (a typical Tsundere). A common gag is that newer characters cannot remember Kotegawa's family name, presumably due to the fact she is generally an unwilling participant in Lala's frequent schemes. Also she really likes cats – owning cat based books, having a stuffed cat, decorating her room with cat shaped things, shaping her chocolate into a cat's face, and even having a cat-themed floaty, something Rito seems to find cute about her. According to Mio, her measurements are B88, W59, H87.

* She also appeared in Mayoi Neko Overrun! as a walk-on character.

RUN/REN ELSIE JEWELRIA Profile

Ren/Run Elsie Jewelria (レン／ルン・エルシ・ジュエリア, Ren/Run Erushi Jueria?) Voiced by: Fuyuka Ōura

A childhood friend of Lala, Ren is infamously known for wearing girls clothing during his play dates with Lala when he was a child. He arrives on Earth to win Lala by proving he is "man enough" for her, but becomes jealous of her relationship with Rito. Due to his pursuit of her, he accidentally gives Rito his first kiss. While Ren is furious, it has an unexpected consequence towards his "alter ego". As Ren is from planet Memorze (メモルゼ, Memoruze?), he can change gender in mind and body upon triggering a specific stimulus; in his case, a sneeze. As a girl, Run (ルン, Run?) is in love with Rito, due to the kiss, and blames Lala for her misfortunes, while Ren is still in competition, albeit one-sided, with Rito for Lala's hand in marriage. Currently, Run is a famous idol, having released several albums. She becomes friends with Kyoko after Run played an antagonist in her show and now are often seen together, even releasing a few albums together.

In the anime, while Ren appears a few times, Run is the dominant personality of the two, who is more serious about her feelings towards Rito to the point of stalking him, even taking a simple misunderstanding from him into her believing all men are never serious about her feelings.

Run appears in Mayoi Neko Overrun! as a cameo on a poster.

RIN KUJOU and AYA FUJISAKI Profile

Rin Kujou (九条 凛, Kujō Rin?) Voiced by: Mai Hashimoto [1] and Aya Fujisaki (藤崎 綾, Fujisaki Aya?) Voiced by: Kaori Mizuhashi [1]

Saki's loyal and assisting friends, Rin is skilled in the kendo arts and has been a loyal bodyguard of Saki for years, as her family has always served the Tenjouin in this position. The bespectacled Aya is weak-willed and became associated with Saki after she and Rin protected her from bullies when they were kids.

SAKI TENJOUIN Profile

Saki Tenjouin (天条院 沙姫, Tenjōin Saki?) Voiced by: Ayako Kawasumi

The arrogant queen bee of the school, third-year student Saki consistently tries to one-up Lala, stating there can only be one "queen" in Sainan High. She once tries to seduce Rito to make Lala jealous, but when that does not work, Saki takes up any excuse to physically assault Rito. She gains a crush on Zastin, only to be horrified when she discovers he is Lala's servant. However, this makes her very determined to win his heart, at any cost. Though she can be stuck up and prideful, she has shown a kinder side to people in need, as when she saved Aya from bullies and Riko (Rito's female counterpart) from the perverted principal.

In the anime, Saki attempts to seduce Rito throughout the series and does not look at Zastin the way she does in the manga.

In Mayoi Neko Overrun!, she is shown with her two friends at a ball.

RISA MOMIOKA and MIO SAWADA Profile

Risa Momioka (籾岡 里紗, Momioka Risa?) Voiced by: Ryōka Yuzuki and Mio Sawada (沢田 未央, Sawada Mio?) Voiced by: Chiemi Chiba

The mischievous, cheerful best friends of Haruna, Risa and Mio spend as much times as they can with her and Lala. Whenever Lala inquires about Earth culture and habits, the two divulge as much information as they can for her (although it is often misleading and perverted). Risa and Mio are known for their playful habit of groping other girls. Recently, it is shown that Mio enjoys cosplay and works at a maid cafe As well as it has been shown that Risa might have feelings (or at least lusts) for Rito, but it hasn't been detailed if she was serious or joking.

KENICHI SARUYAMA Profile

Kenichi Saruyama (猿山健一, Saruyama Ken'ichi?) Voiced by: Hiroyuki Yoshino

The perverted best friend of Rito, Kenichi has known him since junior high and is more open and obvious of his obsession with girls and is one of the few male characters Rito can talk to about his situations involving Haruna or Lala. He is aware of Rito's feelings for Haruna and consistently advises he get together with her. Recently, Kenichi reveals his crush on a girl named Riko, but does not realize she is actually Rito, who is accidentally transformed into a girl by one of Lala's bizarre inventions.

MIKAN YUUKI Profile

Mikan Yuuki (結城 美柑, Yūki Mikan?) Voiced by: Kana Hanazawa

Rito's independent and reliable 12 year-old sister, Mikan takes care of the housework while their parents are away on business and watches after Celine. In contrast to her brother, she is very mature and does not hesitate to tease him, going as far as stating they aren't blood-related, just for a laugh. Mikan also seems to have a certain lack of respect for Rito because of this (she hardly ever addresses him by his honorific as an older brother), but does answer him "Onii-chan" as thanks for trying so hard to take care of her when she develops a fever and when he gives her a Christmas present. Mikan may not show it, but she cares very deeply for Rito and misses his company, to the point one could suspect her of having a brother complex, this more evident in the second OVA where she wondered if he would marry her if they were not blood related, and in the manga where she blushes every time another character mentions her brother. She also states how she and Rito used to play together before Lala entered their lives. It is later revealed that Mikan is terrified of thunder and lightning, though Rito would always comfort her.

Mikan grows quite attached to Golden Darkness, perhaps due to Darkness seemingly being the same age as her. Mikan is very perceptive and seems to be able to read people's emotions, even their reactions, most of which is Rito's obvious anxiety around Haruna and Yui Kotegawa's subtle feelings for him. Mikan even calls him a "playboy" (so does Nana) for attracting so many girls all of a sudden. Mikan, however, does respect Rito's relationship with Lala, even going so far as to tell Momo not to get too close to Rito for Lala's sake. Although it is fairly obvious that she could have done this out of jealousy from how close Momo was getting to Rito.

Mikan and Celine both appear in the series Mayoi Neko Overrun! as customers.

ZASTIN Profile

Zastin (ザスティン, Zasutin?) Voiced by: Takehito Koyasu

Lala's personal bodyguard and the best swordsman on Deviluke. Initially, Zastin disapproves of Rito, deeming him weak and subsequently soughts to test his strength. However, once Rito exclaims his opinion of marriage in self-defense, Zastin is swayed by his words (though not in the way Rito intends) and summarily approves of him, believing he truly understands Lala's feelings. He is currently working as the assistant chief to Saibai; the funds he gets for his duties are handed to Lala for her use. Zastin has shown a keen interest in becoming a mangaka, professionally. He has two assistants that work under him, simply known as "Maul" and "Smutts". Zastins' tail is thin and very scorpion-like in appearance.

Despite his skill with the sword, Zastin has a horrible sense of direction, resulting in him getting lost (one of the running gags in To Love-Ru). He also seems to have extremely bad luck, where he keeps getting run over by trains and cars.

PEKE Profile

Peke (ペケ, Peke?) Voiced by: Satomi Arai

Lala's all costume robot, who acts as a module to form her clothing. Peke is exceptionally devoted to Lala and has the ability to shapeshift into any kind of clothing for her to wear, but this also drains her power supply. As her batteries run out, the clothing Lala wears will slowly dissolve, until it completely disappears. To recharge, Peke simply needs to sleep. Using a dress-form program, Peke has the ability to take on a human form, with the appearance of a young girl.

HARUNA SAIRENJI Profile

Haruna Sairenji (西連寺 春菜, Sairenji Haruna?) Voiced by: Sayuri Yahagi

One of Rito's classmates and the girl of his affections, Haruna has similar feelings for him, having been attracted to his kind, gentle nature since junior high. Despite her growing love for Rito, which she believes to be unrequited, she usually suppresses her feelings and cannot confess to him because of her friendship with Lala, who also loves Rito. However, with some encouragement, she tells Lala of her ordeal, to which Lala accepts, claiming Haruna as her rival for Rito's heart, while remaining friends. She lives with her older sister in an apartment and has a severe fear of ghosts and the supernatural, the exception being Shizu Murasame, to an extent. When frightened, she has a habit of grabbing the nearest thing around her – typically Rito – and swinging wildly, in an attempt to get rid of whatever frightens her. There is also a running gag to where Rito is about to confess to her, only for something (or someone) to come between it.

A highly responsible person, Haruna's personality can sway her classmates' hearts to vote for her as their class representative, even when she did not run to be a candidate. She is affiliated with the tennis club and a southpaw. According to Mio, Haruna's measurements are B78, W55, H80.

LALA SATARIN DEVILUKE Profile

Lala Satalin Deviluke (ララ・サタリン・デビルーク, Rara Satarin Debirūku?) Voiced by: Haruka Tomatsu

The female protagonist of To Love-Ru, Lala is the princess of Deviluke, whose family rules the Galaxy. As such, her hand in marriage is sought from across the Galaxy as she is (presumably) the successor to the Galaxy's throne. A rather childish girl, she is somewhat näive regarding the culture and customs on Earth. Lala initially runs away from home, as she does not wish to get married to any of her suitors, and due to an accident, ends up naked in Rito's bathtub. Upon arriving on Earth, Lala pretends to love Rito to keep herself from getting married, but really does fall in love with him after she misinterprets a statement that Rito shouts in self-defense.Although Lala appears to be somewhat airheaded, she is well known on Deviluke for her genius-level intellect and enjoys making all manners of inventions, often prompting some disastrous effect or another. Throughout the series, she frequently tries to get Rito to love her, although her grand gestures generally end up putting Rito and company in embarrassing situations. Although Rito frequently chastises her for causing embarrassing and otherwise troublesome incidents, Lala rarely shows any form of negativity towards him and even states it is impossible for her to hate him. Even after finding out that he was in love with Haruna as well, she instead cheered and stated that they could both marry him, and becoming even happier after he accidentally said "I love you" to the rest of the female cast, as they could all be together.

Eccentric, playful and intelligent, Lala isn't shy, to a point where it feels almost natural for her to be in the nude (the only exception of this occurs when Lala catches a personality changing fever from another planet, making her very shy). Like all citizens from Deviluke, Lala's physical abilities vastly exceeds that of a human (in one instance, she manages to blow away a typhoon just by shouting) and has a distinctive tail with a shape of a spade on the end that can shoot a destructive beam. Oddly, her tail is very sensitive, causing her friends to nickname it her "weakness" (all female Devilukeans' tails are more sensitive than a male's) despite being able to throw Run and Saki to a wall while they mess with it. Unfortunately, Lala is bad at cooking. The food she cooks is either inedible or extremely spicy. While the fact that Lala is an alien is initially a secret, it becomes common knowledge relatively soon after her arrival with no one making a big deal about it. According to Ringo, Lala's measurements are B89, W57, H87.

YUKI RITO Profile

Rito Yuuki (結城 リト, Yūki Rito?) Voiced by: Akeno Watanabe

The male protagonist of To Love-Ru, Rito is a 16 (currently 17) year-old high-school student. Rito used to be on the soccer team in junior high and was quite good, but quit because he was constantly helping his father with his mangaka duties, thus did not want to leave his sister Mikan alone in the house. Mikan comments he is very good at the most "useless little things", like crane and festival games (e.g. hoops, catching fish, squirt guns). Along with the numerous useless little things Rito is good at, he is also an accomplished florist, gardener, and horticulturalist.

Rito's nature is borderline clumsy, where he always ends up ogling or groping the many girls in the series (though mostly unintentionally). It is only by accident that he encounters Lala Satalin Deviluke, and despite his enduring feelings for Haruna Sairenji, Rito shows signs of developing deeper affection towards Lala throughout the story but is unsure if what he feels is actually love. This is shown again when he couldn't help but think about Lala even though he was with a naked Haruna. It is recently revealed that he is in love with Lala, but he is also in love with Haruna. At the end of the series, he confesses to Lala, but tells her he also loves Haruna, yet she is happy on both parts. He is confused as polygamy is illegal in Japan where Lala replied that once he is king of the universe the laws of earth no longer apply and forces him to go tell Haruna (strapping a jet pack to his back). Right before he was about to tell her, she moves out of the way, just like when he confessed to her very early in the series, leading him to state "I love you" to all of the female cast with the exception of Momo, Mikan, Golden Darkness, and Haruna herself. The ending implies that his "love" troubles will continue on into the future.
