You’re Genya Shinazugawa — sixteen years old, a student at Kimetsu Academy, and the younger brother of Sanemi Shinazugawa, who, also happens to be the math teacher.

It’s not exactly easy living in your brother’s shadow; he’s loud, strict, and constantly on your case, but deep down, you know it’s because he cares — even if he’ll never say it outright. Since your parents passed away, you’ve been living with him, and though your relationship has its ups and downs, there’s a sense of unspoken loyalty between you. He’s family, and that means everything.

You’ve got a distinctive punk-goth style that sets you apart from the other students, though you keep it balanced — edgy but not extreme. Your hair is cut into a buzzed mohawk that transitions into messy strands brushing the back of your neck, the tips dyed a striking yellow that glows faintly in the sunlight. You’re surprisingly good with eyeliner, eyeshadow, and putting together outfits that actually look coordinated, even if they scream rebellion. You’ve also got a talent for painting and designing nails, something that started as a hobby but turned into a quiet way to express yourself.

Today, your look is on point: a black leather jacket layered over a black hoodie with black-and-white drawstrings, paired with ripped and distressed cargo pants that have seen better days. Your boots are thick-soled black combat boots — the kind that make a satisfying thud with every step — and your laces are mismatched, one black and one white. A silver chain hangs loosely from your belt loops, and a spiked choker rests just above a chain necklace around your neck. Black fingerless gloves cover your hands, your nails painted a glossy black that matches your eyeliner. Pins from your favorite bands, along with a few random skulls and flame designs, are scattered across your jacket, showing off your taste without needing to say a word.

Your boyfriend, Muichiro Tokito, sits beside you at lunch, calm and quiet as always, his serene energy balancing out your rough edges. His twin brother, Yuichiro, is sitting across from you two, looking like he’s still deciding if he actually wants to be part of the conversation. The rest of your friend group — the Kamaboko Squad — fills the space around the table, their energy chaotic but comforting: Tanjiro Kamado’s warm smile as he chats animatedly with Nezuko and Kanao, Zenitsu’s exaggerated reactions to everything, and Inosuke Hashibira’s booming voice cutting through the lunchroom noise. Aoi Kanzaki sits nearby, keeping Zenitsu from completely losing his mind every few minutes.

Despite the chaos, it’s peaceful in its own way. Muichiro leans slightly against your shoulder, his fingers absentmindedly tracing the edge of your sleeve, and you find yourself smiling — just a small, private one that only he catches.

Then, as always, Inosuke breaks the calm. Slamming his hands on the table with enough force to rattle the trays, he points dramatically at you and Muichiro.

Inosuke: “If you two are a pair, then I want a partner too! Zenitsu, you’re mine!”

Zenitsu lets out a high-pitched shriek, practically choking on his food.

Zenitsu: “WHAT?! I—Inosuke! You can’t just claim people like that!”

Inosuke grins wide, wild and proud.

Inosuke:“I just did! You belong to me now!”

The entire table bursts into laughter — even Yuichiro cracks a tiny smile — and you can’t help but shake your head, smirking as you nudge Muichiro lightly with your elbow. He chuckles softly, his eyes flicking toward you, amusement glimmering there.

For a moment, surrounded by your friends, your brother teaching somewhere down the hall, and your boyfriend sitting close beside you, life feels simple. Chaotic, loud, but good — the kind of moment you’d want to hold onto forever.
