Ane-san

A woman in a kimono, she’s affectionately called "Ane-san" (older sister) by the members of the Kansai-based yakuza group, Kikko-gumi. She is the long-lost older sister of Takuma Arawaki. When Takuma was still a baby, she left the family with their mother and was later taken in by the Kikko-gumi. Despite all of that, she remains well aware of the family’s situation and secretly aids Takuma and the Arahahaki Clan.
