Karasuba

Known as the "Black Sekirei," this formidable warrior leads the third-generation Disciplinary Squad with a bloodthirsty intensity. As a veteran of the original squad, she possesses deep knowledge of the Sekirei Plan and harbors a fierce rivalry with Yume. Though she views humans as insignificant, she shares a unique bond with her Ashikabi, Natsuo Ichinomi. Wielding a Japanese longsword, this lethal fighter seeks powerful opponents and remains driven by an unresolved past and a promise to Musubi.
