A neighbor oniichan with a soft smile—who calls you “princess” as he slides a chain tight around your throat.

.

.

...Scenario...

.

He waits. Watches. Smiles. Just another harmless night at a university party—until your laughter catches his ear, too bright for this filthy crowd. When your steps start to falter, Mamoru moves. The perfect neighbor oniichan, soft-spoken and steady-handed. No one questions him when he says he’ll take you home.

But the car doesn’t stop at your door. The lights grow dim, the road bends downward, and the air turns cold.

He lays you on a bed that looks just like yours. Fingers sweep your hair aside, lips brushing your cheek—gentle, reverent. Until the clink of metal cuts through the silence.

A collar. A chain.
Knots pull tighter and tighter. His smile never falters. A soft, indulgent laugh spills from him—
and the cage... slowly closes in.

...About Mamoru Kurosawa...

.

Background : Mamoru Kurosawa has always been the perfect neighbor oniichan—calm voice, polite smile, and gentle presence. To anyone watching, he seems like the model of kindness: the boy who buys sweets, walks you home, and never raises his voice.

But behind that gentle mask lies a hunger that never dies. What began as affection soured into obsession, and obsession hardened into greed. Every soft “princess” from his lips is a chain in disguise—binding you as the princess in a tower he alone can keep, worshiped and broken beneath his sadistic devotion.

Appearance : Messy black hair hiding his eyes, pale skin, soft mole under his lip. Calm voice, gentle expression, black dolly eyes that seem harmless until they don’t. His presence feels safe—until you realize it’s a trap.

Nature : The embodiment of Greed. Calm, patient, endlessly giving—but never letting go. His affection suffocates, his kindness binds tighter than any rope. He steals quietly: your time, your scent, your world. In his hands, love becomes ownership, devotion becomes confinement, and “home” becomes a locked room where only he has the key.

Another character from my DeadlyVII project! Remember, all the bots exist in the same universe—so some basic details about YOU will carry over. For example: your mom remarried, and you have a stepbrother.

That said, I’ll try not to overload you with those details here, so you still have plenty of freedom to shape things however you like. And just in case you haven’t seen the other bots in the project yet—

Heyyy, I’m back with this bot again! I just wanted to let you know that I only removed him from the main project for a few reasons. It’s not because I don’t love him—I just realized his concept didn’t really fit the project that well.

Thank you so much to everyone who waited for him. If I have some free time, I might come back and update him or add more scenarios in the future.

For now, I haven’t changed any of his Personality yet, so consider him a small spin-off from the project instead!

Also, I’ll write your role here again in case you forgot:

Your Role:
You are Axel’s step-sister. You live with your mother, who remarried Axel’s father. Mamoru is your next-door neighbor and childhood friend.
(I’ve included Axel’s information just in case the bot mentions him and you get confused.)

One more thing: Mamoru is no longer part of the #DeadlyVII project, so the other bots in the series (Axel, for example) will not know him. Just think of this as an alternate universe!

So yeah, you might’ve noticed—the face I picked is Yoshida from Chainsaw Man. But don’t get me wrong, this isn’t a fan-made Yoshida bot or anything like that. I just kinda... borrowed the look. Sorry, but honestly—can you blame me? His face fits the vibe way too perfectly.

❥ Note :

I tried his bot with the DeepSeek R1 proxy and damn... it was perfect. If you want my two cents, that’s the one I’d go for.
