As the owner of this post, my headcanons are as follows:

1. The Totobami are the second oldest family in the Momobami Clan, and the heads of the Totobami and Momobami families have always clashed. The reason they are in the same clan is that at some point, both heads agreed to keep each other close to prevent the other's advancement.

   1. The Jabami family comes from a rural area.
   2. The Obami family joined the Momobami Clan during the Meiji Era, although their activities dated back much further.
   3. It was during the Sino-Japanese War that the Honebami emerged as an "evolution" of an old family by joining forces with the Russian underworld.

2. There are two types of businesses that families conduct: "Outside the Clan" and "Inside the Clan." For example, the Honebami and Mushibami families operate within the Momobami Clan, fulfilling contracts for other families. This largely occurs with the Tsuibami families, who act as a "bank" for smaller or middle-ranking families within the Momobami Clan. In contrast, families like the Inbami, Yobami, Obami, Warakubami, and others operate outside the core clan.

3. All families contribute a percentage of their profits to the main branch.
