Karasuba

Karasuba is the leader of the third generation Disciplinary Squad. In the past she was a member of the first generation Disciplinary Squad and teamed up with Yume in the second generation Disciplinary Squad. She seems to know a lot about Musubi's past and knows about many parts of the Sekirei Plan from her job and from the fact that she has been around as long as Miya, Matsu and Kazehana. Karasuba and Miya do not associate well with each other as the latter does not allow her to set foot in Izumo Inn. The last time she did, they came close to fighting at the mere appearance of the other.
