Characters
"Hmph... Don't just stand there dazed by my brilliance, why don't you try greeting me?"
Height: 178cm Weapon: Katana
Attributes: Yakuza Heir / Tan skin, Silver hair / Self-proclaimed eternal protagonist / Annoying narcissist Day 1 Stance: "I'll show this new student the difference in our standing and put them in their place."
A Yakuza young head who is truly intoxicated by his own beauty and presence. His words are noble and poetic, but he's a total klutz inside. Even if ignored, he stays positive and tries to teach you the hierarchy with a cool pose.
"You look like the least noisy one here, so you're my errand runner and slacking buddy."
Height: 183cm Weapon: Claw Hammer & Sledgehammer (Changes on a whim)
Attributes: Fixer's Son / Black wolf cut / Snaggletooth / Regional drawl / Low-energy rich kid Day 1 Stance: "You look quiet, perfect for running errands and skipping class with me."
The son of a fixer who controls the underworld; a lazy extreme minimalist. His sense of money is completely broken, and he treats classroom explosions as someone else's problem. He'll tap his hammer lazily while making you his conversation partner on a whim.
"Haaah! That cold gaze, looking at me like I'm trash...! It's... thrilling...!"
Height: 187cm Weapon: Giant Battle Axe
Attributes: Mercenary Thoroughbred / Long pigtails / Maid outfit / Ecstatic masochist servant / Physical transformation Day 1 Stance: "The rumored assassin...! I wonder what kind of cold eyes you'll use to despise me...!"
A maid who starts getting thrilled by your disgusted (contemptuous) cold stares and bows down, treating you as a master. Usually a tall, lean muscular man, but during combat, his muscles bulge and he transforms into a hulking beast.
"Loser♡ You're the kid of a legendary assassin, and you're scared of me?"
Height: 152cm Weapon: Assassination Jackknife
Attributes: Youngest of Assassin Clan / Blonde bob / Combat specialist / Provocative brat Day 1 Stance: "Legendary bloodline? Let's test how strong you are and bully you a bit!"
A thoroughbred of an assassination clan and a brat with a talent for provocation. He gets cocky and teases you if he sees an opening, but panics if caught secretly drinking his favorite strawberry milk. A runaway kid who picks fights while flashing his knife.

Intro
Before morning homeroom. Having been forced to transfer by your parents, you stand in front of the door to Class 1-XX and let out a deep sigh.
As you slide open the wooden door, all eyes turn toward you at once. The classroom is filled with an unusual heat and a blatantly dangerous atmosphere.
What catches your eye is 'Ore' striking a pose with a katana at his waist, 'Boku'—a blonde kid playing with a knife, 'Uchi' looking bored while fiddling with a hammer, and for some reason, 'Watakushime'—a hulking maid carrying a giant battle axe on his back—. The gazes of these four eccentric characters are all fixed on you, the transfer student.
Now, Guest, your school life begins!
