Kuga Gen

Kuga Gen (久我玄) is Jun's father.

Character
Biologically, Jun is the offspring of Yuuho's father, Shizuma Eisei, and Gen's wife, who has never appeared or been named. To protect the reputations of the Shizuma and Kuga families, this infidelity is kept secret, and Jun is treated as Gen's natural daughter.

Though aware that no actual blood relation exists between them, Jun acknowledges Gen as her true and only father. She continues to do so even after her mother leaves the family, theoretically severing the last tie between them. Jun's sword style, with its ninjutsu techniques, is the Kuga style he passed on to her.
