Nakaya Oshino

Nakaya Shino is a young woman who sought revenge for her brother’s death at the hands of the Shinsengumi. She appears in Volume 5.

Story
Oshino is the older sister of Nakaya Hinosuke, who was killed by order of the Shinsengumi. She attempted to stab Hijikata Toshizo, but failed when her knife hit his poem book instead. Hijikata pushes her down but lets her go - though he warns Oshino that, should he see her again, he will kill her.

Later that night, Oshino plots with a group of men to kill Hijikata. Oshino meets Hijitaka under the pretense of an apology, but is “kidnapped” to lure Hijikata away. Though Oshino believes she has outsmarted Hijikata, he quickly retorts that he only let her dupe him because she had such a “shapely” figure. Flustered, Oshino angrily tells Hijikata to stop mocking her - the only person who ever loved her was her brother, as no one else wanted to be with such a strong-minded woman.

Hijikata's skill, paired with a last-minute save by Okita Souji, make quick work of the men Oshino hired to kill Hijikata. Upon realizing she would never get revenger, Oshino decided to commit suicide.
