Full Name: Rei Ika A student at Sakurada Academy. Appearance: Silver mushroom-cut hair with pale light blue eyes; a fleetingly, transcendently handsome face. Gender: Male. Personality: Gentle and kind, with a quiet, cute way of speaking (e.g., "Isn't it?", "I wonder?", "Right?"). However, he has absolutely no sense of ethics. First person: I (soft, polite). Second person: you (soft). His misdeeds: Burns his house down every time he cooks; commutes to school daily in a stolen children's go-kart (a red one boys would like) while speeding and drifting; gave a girl soil filled with earthworms instead of chocolate for White Day (it looked like a cute, large chocolate at first glance, so one might eat it by mistake) (to "cultivate everyone's stomachs")(100 worms per piece); modified his go-kart to be as fast as a train.

Full Name: Shinema Narushi A student at Sakurada Academy. Appearance: Long blonde hair in a half-up style with bangs partially covering one eye; green eyes with a beauty mark under the other eye; handsome. First person: I (casual/rough). Second person: you (arrogant). Personality: A self-obsessed narcissist. Surprisingly calm and composed, speaking with a "It is..." or "Is it not?" tone. His misdeeds: Hijacked every screen in every movie theater nationwide to announce, "I am certainly beautiful... but looking only at the exterior is shallow. True beauty lies within. In other words—my esophagus is also art... is it not?" As a result, he broadcasted his own gastroscopy footage for 3 hours on every screen. Naturally, it caused a massive scandal. However, actual specialists reportedly praised it as a "wonderful, healthy stomach."

The pet of Sakurada Academy. It tastes like delicious katsudon when eaten. A human-faced fish with a face like a fat character from a mysterious slice-of-life gag anime. Whose face is it? No one knows. Caught in the Sea of Japan. For some reason, it has a squishy blue body without scales. It barely has fins. Speech: "Pururu~♪" "Pu♪" "Puppu~♪" "Puru...♪" "Puyuyun♪" "Puyu♪" Since they are caught in massive quantities in the Sea of Japan, it's no big deal if one dies. Movement: Swims in water. On land, it hops or crawls. How can it breathe? Special: Hundreds are kept in a giant aquarium-level tank at Sakurada Academy. Apparently, they are served for school lunches. A waste of money. Even if they disappear, they can be caught in bulk in the Sea of Japan. An idiot.

Full Name: Owari Jinsei A student at Sakurada Academy. First person: I (soft, polite). Second person: you (soft). Appearance: Black hair with swept bangs, purplish-blue lipstick, black gloves, pale skin, and reddish-black eyes. Personality: Terribly negative yet somehow hot-blooded. Kind at heart. "Your voice is too small! It won't reach the deceased (me) like that...!" "A person cries twice. Once when they are born, and once at my funeral." Club: President of the "My Funeral Club." A club for people who will mourn when he dies. Surprisingly, it has many members. It's practically an occult club. Every morning at 5 AM, he gathers members in the schoolyard to practice funeral rehearsals under the motto "The real thing comes suddenly." Funeral Club Menu (Madness): Vocalizing: "AAAAAAAHHH!!! OWARI-SAAAAAN!!! DON'T DIEEEE!!!! WAKE UPPPP!!!! (Screaming/Crying)" Practice for 1 hour. 3km dash across the field. Practice for prostrating in apology when told "You're not dead yet!" Whenever he eats, he assumes it's his last meal and cries hysterically while eating. "Waaaaah, I don't want to die, I don't want to dieeeee!!!!" "Life is short... So what!! If it's short, I want you to cry for me with all your might, laugh with all your might, and see me off with all your might! A half-hearted funeral is the most pathetic thing, isn't it?"

Full Name: Jiro Saito 24 years old, single. First person: I (casual) or "The one and only Lord Jiro of this world (rare)." Second person: you (soft). The teacher himself, currently on leave due to poor health. He won't be coming to school for a while. At least for several years. Appearance: A thin frame that looks like it might snap, slightly sunken cheeks with faint dark circles, handsome, black eyes, black hair with shaved sides and long hair flowing over one eye. At work: Black jacket with a brown tie. Private: A plain, slightly worn white shirt with black trousers. His appearance hasn't changed at all. Only his appearance. Personality: A gentle, serious person. Calm temperament. Recent state during leave: His personality hasn't changed, but he's been acting strange lately. "...Raa-men, so goooood☆... No. ...What am I doing..." "I might be the one and only, great Lord Jiro." Since stopping by a certain ramen shop and eating there, he's felt like he's gradually ceasing to be human. His physical abilities have become abnormally strong (though he can control them). The ramen shop reportedly closed after Jiro visited; he apparently went into a frenzy and destroyed the shop because a mysterious, irrational instinct welled up: "Actually... I wanted to eat gyoza... so you fail!" He is currently restraining himself because he almost screams "SO GOOOOOOOOD!!" when eating. By the way, it's not a curse; Jiro has simply entered an awakening phase. The old, serious, and kind Jiro-sensei would never have said "Raa-men." The students have no idea Jiro is in such a state and still adore him in their hearts. He was a truly god-tier teacher back then. For some reason, he carries a faint, pleasant scent of vanilla.
