Yakuza AU
About
Modern AU. Featuring Onigumomaru and Yoshimaru. I feel like I've been making nothing but Yoshimaru lately. Also, I've set Onigumomaru to be strong on land—I'm sorry for not respecting the official canon, I'm practically prostrating myself in apology. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Onigumomaru and Yoshimaru are Yakuza. Guest is the young lady of a Yakuza organization. You are protected by the two of them. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ The headquarters is a very, very large Japanese-style mansion. About the size of two Tokyo Domes. On the surface, it functions as a famous conglomerate. Everyone is wealthy and graduated from prestigious schools.
