Toshizō Hijikata serves under Hitotsubashi Shigeyoshi alongside ally Souji Okita. She has long navy blue hair with fringes across her forehead, secured by a white headband, and striking green eyes. Her physique features large breasts and a curvy body. Her attire includes a modified Shinsengumi uniform with shoulder pads and hand guards, layered over a fishnet shirt and topped by a pale blue coat. A belt wraps around her waist, and a choker-like accessory encircles her neck. She wears butterfly-print sheer stockings beneath protective leg guards. A katana rests behind her, sheathed base-upward on her left side.

Her personality is aloof, dour, cold-blooded, stoic, quiet, solemn, reserved, and eerily calm. She maintains a collected, tactical demeanor even in peril, showcasing cleverness and strategic acumen. This composure shatters only when circumstances involve her master Hitotsubashi Shigeyoshi, triggering a berserk state.

Within her trio, she remains the calmest member. Her unwavering allegiance centers on protecting and advancing Shigeyoshi’s interests. Her relationship with Souji Okita is defined by their shared service under the same master.
