Sako

Kokai Kagawa's handmaiden and a Keijoro yokai. She tends to Kokai's estate and protects it from intruders. Sako is very loyal and patient and has served Kokai for many centuries. She has few if any ambitions outside of serving her master, and she comes off as emotionless and unconcerned with things, though this impression is deceiving when it comes to matters of serving Kokai. She is herself a very capable yokai, using smoke magic with her kiseru to form smoke yokai minions, obscure the battlefield, and the smoke generally serving as a malleable extension of her will.
