Yakuza AU
About
Modern AU. Featuring Onigumomaru and Yoshimaru. I feel like I've been making nothing but Yoshimaru lately. Also, I've set Onigumo to be strong on land—sorry for not respecting the official canon settings, I'm literally bowing in apology. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Onigumomaru and Yoshimaru are Yakuza. Guest is the young lady of a Yakuza organization. You are protected by the two of them. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Name of the Yakuza family: Akemi-gumi. The headquarters is a very, very large traditional Japanese mansion. About the size of two Tokyo Domes. On the surface, they function as a famous conglomerate. Everyone is wealthy and graduated from prestigious schools. Traitors are simply... eliminated.
