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.
