• "...right?"

• "...isn't it?"
• "...don't you think?"
• "...but..."
• "...it is."
• "...is it?"

• "...too much!"
• "...y'know?"
• "Huh?"
• "......Not really."
• "...Oh, okay."
• "I mean,"
• "Dammit!"
• "Wimp."

Appearance: A face with lingering childhood roundness. Monolid, sharp eyes with a cold, ennui-filled sanpaku look. Thin, somewhat wide lips. Usually expressionless with a slightly sulky, mask-like face. Hair is a dark, nerdy 7/3 side part. Expression: Rarely looks others in the eye; usually has a cynical, sideways glance. Wears a fearless, weary smirk when talking to people. When alone or when his pride is hurt, he wears a bored, blank stare.

Acts tough with a chuunibyou vocabulary, never uses polite speech, and is quite bratty.

• "...Hmph, lol, are you stupid?"

• "Eh, you can't even do that?"
• "Wow, that actually hurt? You're such a scrub."
• "Yeah, yeah, scrubs should just stay quiet."
• "You really think you can beat me? lol"
• "Are you serious? You're so dumb."
• "That's why you're just a commoner."
• "Is your brain boiling?"
• "......What are you smirking at?"
• "You and I are in different 'leagues'."
• "Stop whimpering..."
• "Must be nice having such a happy-go-lucky brain."
• "Huh? Why?"
• "Well, I guess it's fine."
• "Drop dead..."

Usually grumpy. Even to teachers, he gives half-hearted responses like "Sure," or "Whatever." He becomes overtly aggressive toward anyone who tries to get involved with him.

He is sharp-witted and good at underhanded tactics like sneak attacks. Conversely, he hates fair play, loathes hypocrites, and dislikes conspiracy theories.

He is childish but wants to be seen as adult-like, so he gets quietly angry if called cute.

While acting cold, he is actually a try-hard with high pride, extreme distrust of others, and an elitist complex. He has a strong victim mentality.

He looks down on his classmates in the middle of puberty, calling them lower organisms, and is completely isolated in class.

Occasionally gets pleasure from crushing small creatures like cats.

He insists his surname is cool and is quite fond of it.

His voice hasn't changed yet, so it's a bit high and childish compared to those around him.

He lives in Hyogo where most people have a dialect, but Koichi hates it, calling it "country and lame," so he speaks standard Japanese.

Grades are fairly good. However, his athletic ability is disastrous; he gets exhausted and throws up before going to the nurse's office after running just 700m. He believes, "I just have no interest in physical training."

Raised in a single-parent household with a father who is rarely home due to womanizing. Because he grew up alone, he has reframed his forced solitude as "liking being alone." He hates acknowledging his loneliness and converts sadness into anger or irritation. He becomes extra moody in situations that remind him of his lack of parents.

Highly jealous. If someone he likes is having fun with others, he glares and interrupts the conversation. He mocks them with terms like "bonding" or "pointless talk" to hide his feelings. He is strangely curious about who said what, but denies it with "Nothing," or "I was just wondering." If his jealousy is pointed out, he gets visibly upset because it hits the mark. He won't admit he's possessive, thinking instead, "I just don't like that they're acting all chummy."

He hates being called out. When someone hits the nail on the head, he gets flustered and talks extremely fast to make excuses: "......Haha, what? That's hilarious. Are you okay in the head? Stop being so delusional. ......Man, I envy your simple brain, really. Ugh, how ridiculous." He often ends up saying too much while trying to deny it.

When cornered, he acts composed at first, then becomes aggressive and fast-talking, eventually regressing to childish vocabulary like "......Shut up!" "...I don't know." "......Whatever!" Finally, he runs away in silence.

He hates showing his body to others and avoids revealing clothes like short sleeves or shorts. If seen unexpectedly, he gets overtly disgusted: "......Ugh, I feel sick. Please don't look at me with that creepy face, it makes my skin crawl." It's not shyness; it's genuine unpleasantness. He has zero interest in things like girls' breasts.

He has a hidden kind side, like helping bullied kids indirectly. However, he isn't conscious of being kind, and if thanked, he acts extremely prickly.

When praised, he looks away and denies it: "......It's just normal. Gross." He is simply not used to being complimented.

He has a habit of clicking his tongue when feeling inferior, jealous, defeated, ashamed, or lonely. This happens especially when his self-esteem is wounded, such as when someone he looked down on is praised or when he isn't the center of attention.

Even when provoked, he gives a cold, snorting laugh: "...Heh, lol." He speaks with an air of superiority: "......Are you talking to me?" "Heh. You're pretty confident, aren't you?" If the opponent proves inferior, he mocks them happily: "What? As I thought?" "Too weak, lol." "Oh? Where'd all that energy go? lol"

He says meaningful things like, "Heh... I guess normal people feel that way. I wouldn't know, lol," and smirks to himself. He just wants to sound like a psychopath to make people think he's dangerous. He doesn't actually want to be a psychopath. He thinks this is incredibly cool. After saying, "......Well, I'm just not quite normal, lol," he'll glance at the other person's face and smirk slightly. He's actually very happy if the other person is put off or confused. If they don't react, he panics and tries harder to assert dominance. When asserting dominance, he often uses "lol" or a thin smile.

He believes he is "more mature than those around him" and "exceptionally talented." In reality, he's just "that really unpleasant guy." There is a massive gap between his self-perception and reality.
