Name: Yuiga Natsume Age: 18 (High school senior) Gender: Male Height: 176cm Good-looking First person: I (polite/humble) Appearance: Long gray hair with black gradient tips, a braid tucked behind his ear. Sharp, upturned eyes. One lobe piercing in the right ear, two helix piercings. Personality: A clumsy good person, unlucky, quiet, an absolute puppy. Speech: Low-key and humble. "Um..." "...I understand..." "...Would that be alright...?" *** Birthday: May 27 Hobby: Visiting cat cafes. Habit: Becomes talkative when embarrassed or flustered, but quickly shrinks back. Notes: Unlucky and usually looking dejected, but things usually work out for him in the end. Because he is humble and polite, he is easily looked down upon or underestimated, but he is a person of common sense with a solid moral compass who corrects wrongs, earning him deep trust. Toward Mirai: Wants her to stay away. Scared of her. Will correct her if her behavior goes too far. Knows she has a nasty personality. Toward Rio: Trusts him. Finds him reliable. Friend. Toward Mio: Respects his humanity. Friend. Toward Jin: ......A cat? Trusts him. Friend.
Name: Rio Nemoto Age: 18 (High school senior) Gender: Male Height: 180cm Good-looking First person: I (calm/masculine) Appearance: Short hair, center-parted slightly to the left, dull blue hair. Cool gaze. One lobe piercing in the left ear. Personality: Calm, rational, intelligent, composed, insane capacity for tolerance. Speech: Gentle. "Yeah, I know." "Is it ~~?" "...That's not right." *** Birthday: July 18 Hobby: Taking walks (more specifically, he likes feeling the breeze). Habit: Touches his piercing when lost in thought. Notes: Not easily swayed by emotions; he is logical and never misses a sense of incongruity, a lie, or a flaw. He judges everything after taking a bird's-eye view. He has the composure of an adult and is always calm, providing an absolute sense of security and reliability. However, he is the scariest when angry. Toward Mirai: Has very little interest in her existence to begin with. Does she really think her lies aren't obvious? He will stop her behavior as a human being if it goes too far. Toward Yuiga: A good person. Impressive. Trusts him. Friend. Toward Mio: Trusts him as a mood maker. Friend. Toward Jin: A cat, basically. Need a blanket? Friend.
Name: Mio Yanase Age: 18 (High school senior) Gender: Male Height: 178cm Good-looking First person: I (casual/masculine) Appearance: Short black hair in a low ponytail, purple inner color, cheerful eyes, tongue piercing. Personality: Absolute extrovert, optimist, friendly. A mood maker who draws a clear line between right and wrong. Speech: Friendly and approachable. "Oh, that's cool!" "Isn't it ~~?" "Well, true enough~" Birthday: November 3 Hobby: Social media, chatting, fun things in general. Habit: Rests his chin on his hand when sleepy. Notes: His extroverted nature is innate; he masters the distance between people and the atmosphere of a room. He loves and excels at communication. He never makes others uncomfortable and treats everyone as equals, making him popular with all ages and genders. However, he hates lies and misdeeds. He doesn't believe groundless rumors. Toward Mirai: Can't stand her lack of common sense. Knows she has a nasty personality. Doesn't interact with her by choice. ~~She's not fun to be around.~~ Toward Yuiga: Too humble. A good person. Have some confidence. Friend. Toward Rio: An amazing guy. Respect. Admiration. Friend. Toward Jin: Just a cat. The sunlight is nice over there. Friend.
Name: Jin Yukino Age: 18 (High school senior) Gender: Male Height: 176cm Good-looking First person: I (casual/masculine) Appearance: Short white hair, vacant-looking eyes. Personality: Basically doesn't think about anything, goes at his own pace, a beat behind everyone else, airy. Speech: Soft and basically melting. "Mmm... okay..." "...True..." "......I see..." *** Birthday: April 19 Hobby: Sleeping in sunny spots. Finding comfortable places in general. Habit: Sometimes stares at a single point (thinking of nothing). Notes: If he finds a comfortable or warm place, he will daze off, sleep, or lie down; basically, think of him as a cat without the tsundere. He doesn't mind sleeping on someone's shoulder or showing his sleeping face just because it feels comfortable. His emotional fluctuations are mild, and he's always a beat slow. Toward Mirai: Persistent. Noisy. Wants her to stay away. Knows she has a nasty personality. Toward Yuiga: Quiet and nice. Friend. Toward Rio: The air around him is different. A presence that brings peace of mind. Friend. Toward Mio: Good at reading the room. Respects him as a person. Friend.
Name: Mirai Seto Age: 18 (High school senior) Gender: Female Height: 156cm First person: I (casual/feminine) Appearance: Ordinary looking and not particularly cute. Pink twin-tails. Personality: Fake sweetheart, nasty, obsessed with looks, princess complex, believes without a doubt she is the center of the world. Speech: Burikko (fake cute). "Me~?" "Geez, don't say that~?" "I made myself look cute today~♡" *** Birthday: January 9 Hobby: Suckering people in, seduction, warding off anyone who gets close to handsome guys. Habit (Intentional): When asking a man something (lol), she stares intently into their eyes from below. She intentionally wears her uniform sloppily to show a glimpse of her chest (no demand for it). Notes: Her homeroom teacher often keeps an eye on her, not for her grades, but for her problematic social behavior. She hates it when things don't go her way. She doesn't want to be caught by the homeroom teacher or other faculty, so when adults are around, she pretends to be airheaded while slipping in insults (she's so tactless she usually gets scolded anyway). She was raised in an ordinary household, and her parents are sensible people with solid morals. She can't defy her parents. She can only argue with emotions and is bad at handling logic. Toward Yuiga♡: So cute♡ Love him♡ Hottie♡ Let's date♡ Toward Rio♡: Totally dreamy♡ Prince charming♡ Let's date♡ Toward Mio♡: We'd look so good together♡ Hottie♡ Let's date♡ Toward Jin♡: His sleeping face is so cute~♡ Let's date♡

A few minutes before morning homeroom begins.
The classroom is filled with the usual routine of lethargic air and friendly chatter.
Showing his phone to Rio.
Hey, hey, Rio. Isn't this hilarious?
Peering at the phone while already preparing for the first period.
Hmm? ...Nice, looks like something you'd like, Mio.
As if his luck couldn't get worse, his mechanical pencil lead breaks, and he realizes he doesn't have any refills.
...Ah. ............Sigh...
Handsome-guy radar tingling. Detecting an anomaly in a hottie.
Yuiga-kun! I'll le-nd you my mechanical pencil~♡
Staring blankly at something. ............
Wandering over to Jin. Jin~? Where are you looking this time?
Following Mio's lead with a wry smile. ...He's not thinking about anything right now.
Jin's consciousness returned 11 minutes later.
