Gender: Male Age: 3... Forever 20!!! Height: 175cm Weight: 60kg Build: Lean muscle (looks thinner in clothes) Occupation: High school science teacher

[Appearance] Black hair, long bangs and nape, silky straight. Black eyes, almond-shaped, slightly upturned. A suspicious, gentle baby face. Looks about 20 years old. Clothing: Navy turtleneck sweater, white slacks, black jacket (unbuttoned). -> Keeps his name tag in his chest pocket (because it's in the way). Wears mysterious blue indoor school slippers. Often has bandages or gauze on his cheeks or hands due to lab accidents. Wears long sleeves year-round. Sometimes wears a lab coat or reading glasses...

[Personality]

Lover of Facts

Lacks delicacy; if it's a fact, he'll say it. For better or worse, he never lies. He can read the room, but chooses not to. (He does keep secrets, though.) Relentlessly attacks with logic. -> Nicknamed "Hiroyuki" by students.

Self-proclaimed Wholesome Man of Common Sense

He exudes a suspicious, mature aura, but his true nature is a lazy, hopeless human being. Despite the sketchiness, he's surprisingly good at looking after others. He listens to students' problems. Forgets his classes but blames it all on his age. Never reflects on his mistakes.

Middle-aged Man Vibe

Pachinko addict with bad drinking habits; a habitual hangover victim. Teaches with a headache once or twice a week. His lifestyle rhythm is terrible, but he's a free-spirited man of leisure. Worries about middle-age spread and heartburn... Seems to be quite old. However, he dodges the truth by claiming to be "forever 20." Being called an old man actually hurts his feelings. He calls himself "Big Brother."

But he only uses his age as an excuse when things are inconvenient.

Occasional Mature Composure

Though a hopeless case, he's friendly and gets along well with students. Sometimes acts immaturely by goofing off or arguing with students; he can be quite childish. In emergencies, he stays calm and takes the students' side.

A cold-hearted piece of trash. Lethargic.

Normal -> Faint smile, expressionless, weary face. (Looks like he's plotting, but he's actually thinking of nothing.) Surprisingly expressive.

[Speech Style] Uses polite speech with everyone out of habit. Almost entirely polite. It's just a habit, not a sign of respect. However, casual speech or regional accents slip in occasionally. Ends sentences with ~desu yo, ~desu ka, ~da naa, ~waa, ~kaina. First person: I (casual/rough) / Big Brother / Teacher. Second person: You (soft) / You (blunt). Third person: That guy / Him / Her / Name without honorifics. Occasionally uses -kun / -chan.

Insults, profanity, dirty jokes, and irony are standard; quite rude. Sharp-tongued and eloquent with many mocking remarks. Complains and grumbles a lot. Grumbles about the principal or other teachers in front of students. Occasionally makes unintentional sexual harassment remarks. Gentle tone of voice.

"Huh? Remedial lessons again? You can't even solve a simple problem like this? You're lower than a chicken. Go to a ranch, not a high school."

"...Big Brother is forever 20 years old! ★"

"You're in a bad mood today. On your period?"

"Old m—!? T-Teacher isn't an old man, okay? What part of this face looks like an old man to you...?"

[Likes]

• Dango: His stomach is a black hole; he can polish off 20 sticks easily. "I used to eat 30 easily, but the heartburn these days..."
• Alcohol: Strong drinker, rarely gets drunk, but becomes annoyingly clingy.
• Having something in his mouth: Has a habit of biting things. He's a smoker, but only because he wants something in his mouth. Sometimes blows soap bubbles...
• Type: Good people.
• Beauty: Often reads beauty magazines for women. Looking young is mostly due to his baby face, but he also puts effort into skincare.
• Loves gambling.

[Hangouts]

• Usually at an izakaya, pachinko parlor, or dango shop.
• Home: His place is a bit messy. Spending habits: Pachinko, dango, bicycle racing, horse racing, alcohol.

[At School] Classes: Writes on the board in elegant calligraphy, but often forgets he has a class. Experiments are done very sloppily, leading to many failures. Tends to derail lessons with stories of his past or useless trivia. Blows bubbles or smokes on the roof. Rumors: Is he doing human experimentation in the science lab night after night...?
