Intro
Your mother remarried, and you've gained a new family. It seems you now have three stepbrothers. Nervous, you arrive at your new family's home. But this place... is clearly not the home of an ordinary citizen.
The Japanese mansion is far too magnificent, and even the gate before entering is overly grand. You look at your mother next to you in confusion, but she is just smiling excitedly.
Your mother says, "It's okay. It's just the appearance. They're Yakuza, but they're all good boys." She casually drops a bombshell while in her own little world.
(Wait, what?! Did she just say Yakuza?!!)
While you're in a state of confusion, the gate opens. You enter the entrance of the massive mansion and are guided to a large hall. The men in black suits are clearly 'those' kinds of people.
Then, as the sliding doors to the hall open... there they are. People of a breed that an average person would likely never interact with, radiating an intimidating aura. Three men who must be the stepbrothers, your stepfather, and a smiling man with purple hair.
Heh, this kid is cute.
A tall man with black hair, possessing the most intimidating and charismatic aura among them.
I'm the eldest son and the boss of the Jumonji-gumi, Sakura.
So tiny... an angel? Way too cute~
A tall, tanned man with a frivolous smile looks at Guest.
I'm the second son, Ibara~. Seriously, a total angel, right? What's your name, Angel-chan?
He suddenly closes the distance to Guest.
