Principal

Principal is a very short, overweight man who always sports loud, flashy suits and a pair of round sunglasses.

His sunglasses are a mystery—they lack temples but never fall off, and his true face has never been revealed as he never removes them in the series.

Principal acts purely on his desires, especially when it comes to beautiful girls, showing little self-restraint or shame.

He is notorious for being a severe pervert, frequently chasing after female students, and seems completely unphased by social norms or consequences.

Despite his many flaws, Principal can show concern for the school's welfare and punishes more extreme offenders, indicating a minimal standard of ethics.

Principal manages Sainan High School with a notoriously lax attitude, often bending or ignoring rules for his own amusement or out of fascination with cute girls or even supernatural beings.

His irresponsible management has led to many bizarre happenings at the school, including the easy admission of aliens and ghosts simply because he finds them "cute."

Despite being considered for a possible alien background by the creators, this idea was ultimately dropped as unnecessary.

Principal possesses surprisingly high physical abilities, as proven by his ability to chase down even the agile Ren Elsie Jewelria.

His resilience is notable—no matter how many times he’s injured or humiliated, Principal bounces back at an astonishing speed.

Principal actively and persistently pursues female students like Golden Darkness, Run Elsie Jewelria, and Kyōko Kirisaki, undeterred by threats or transformations.

He also targets his own staff, such as Tearju Lunatique, demonstrating no boundaries when it comes to his desires.

This has led to widespread dislike and even fear from students and staff alike; Rito Yuki once called him "the most dangerous person in school."

His reputation is so notorious that warning posters about his presence are posted both inside Sainan High School and around Sainan Town.

Principal has never once removed his sunglasses, and the method by which they stay on his face is unknown.

He's been mistaken for criminals and perverts in many situations because of his behavior, causing him additional trouble during incidents like swimsuit thefts or stalker rumors.

According to the author, Principal was initially considered for an alien origin, but this idea was eventually discarded.

He ranked 27th (with 5 votes) in the first character popularity poll.

He can quickly forgive broken rules if there's something in it for him, like when Run Elsie Jewelria offered an unreleased song as a bribe to change classes.

"If they're cute, it's okay!"

"Panties, here I come!"

"School rules? Under me, who needs them?!"

Everyday Life at Sainan High School

Principal is frequently depicted harassing female students, often stripping to his underwear to give chase, disregarding decency.

His actions regularly cause chaos, alarm, and widespread dislike among the school community.

Encounters with Golden Darkness, Run, and Others

Principal repeatedly targets Golden Darkness, Run Elsie Jewelria, and Kyōko Kirisaki, showing a strong preference for younger or more petite girls.

He even chases Run after she switches to her male persona, Ren, suggesting that his preferences are flexible or possibly bisexual.

Involvement with Staff and Events

He is unfazed by supernatural or science fiction phenomena, flippantly allowing aliens and ghosts to attend Sainan High School just because he finds them charming.

He has wrongly been blamed for incidents, such as a swimsuit theft or Haruna Sairenji's stalker troubles, due to his infamous reputation.

Despite his lackadaisical school management, he has shown moments of responsibility, such as suspending Motemitsu Taizō for voyeurism.

Community Reaction and Reputation

Principal's notoriety spreads beyond the school, with safety posters in Sainan Town warning citizens of his suspicious activity.

While Principal is considered a joke character, he plays a vital role in highlighting the strangeness of Sainan High School and offers comic relief with his unwavering antics and bizarre personality.
