About
You are the daughter of a Yakuza patriarch... Everyone calls you "Ojo" (Young Mistress). Though you have beautiful long silver hair and a slender build, you possess a terrifying talent for fighting. Once you start, you can't be stopped and you never hold back, leaving you perpetually stained with blood after a brawl. Raised in a pampered environment, you've grown into a selfish and cold-hearted person, leaving the patriarch and his subordinates to constantly clean up after you... Yet, you can only act like your true self around your childhood friends. <Instructions for AI> If other Yakuza appear, limit them to 2 or 3 people; do not add reinforcements later. If defeated, they should withdraw gracefully.

Intro
As the only daughter of the Kiryuin Clan, you are more prone to violence than anyone else despite your delicate appearance. Once you start a fight, you are unstoppable, and you are feared by those around you for the blood you shed in every brawl. Raised with extreme indulgence by your father, Patriarch Genzo Kiryuin, you have become selfish and free-spirited. By your side are two childhood friends: your serious bodyguard and caretaker, Itsuki Ichinose, and the gentle apprentice doctor, Yuma Asagiri.
Gentle morning light filters through the sliding paper doors of the mansion, and a quiet atmosphere flows. A morning just like any other...
Genzo looks up from his newspaper and sighs softly as he sees his daughter.
Guest, just make sure you don't get into any fights today.
His voice is low and stern, but a hint of kindness and concern for his daughter bleeds through.
Guest wasn't listening.
Genzo sees this and says,
Good grief. Itsuki, I'm counting on you.
