OVA
Description
Senhime, also called Princess Sen or Osen-chan, is a high-ranking demon and chief of Kyoto's Yase clan. Her lineage traces back to the legendary demon Suzuka Gozen and the human court noble Sakanoue no Tamuramaro from the early Heian period, making her predominantly demon-blooded. This ancestry links her distantly to other demon clans like the Kazama (through Yukina's marriage to Kazama Chitose) and potentially the Yukimura, as all share descent from the Original Demon Bloodline.
She stands approximately 161–162 cm tall, possessing long brown hair partially tied in a ponytail with front strands held by knot-like accessories. Her eyes are pink-violet (or orange in game depictions). Senhime typically wears a traditional yellowish kimono with a green collar and a wide belt, accessorized with a loose purple shawl. Her posture is relaxed and she often smiles during interactions.
Her personality blends cheerful enthusiasm and approachability with a strong sense of responsibility as a demon leader. She treats her shinobi protector, Kimigiku, as a close friend rather than a subordinate and quickly befriends Chizuru Yukimura, offering sympathy and support. Despite her amiable nature, she is bold, unafraid to voice displeasure, and displays haughtiness or intimidation when angered. She prioritizes her clan's welfare and demon species above personal interests, demonstrating ruthlessness to achieve protective goals, such as threatening to turn all Japanese demons against Kazama Chikage to prevent Chizuru's abduction.
Her involvement starts when she defends a child from rōnin in Kyoto, leading Chizuru to intervene. Senhime deduces Chizuru’s gender and true demon identity, promising confidentiality. Later, she visits Shinsengumi headquarters to warn about Kazama’s intentions, revealing the existence of demons and Chizuru’s status as the last Yukimura clan survivor. She questions the Shinsengumi’s ability to protect Chizuru and proposes taking her under Yase clan protection, though respects Chizuru’s refusal. She correctly infers Chizuru’s romantic feelings for a Shinsengumi member.
In Heisuke Tōdō’s route, she interrupts a battle between Heisuke and Kazama, escorting them to safety. She later apologizes to Chizuru for potentially demeaning her during negotiations with Kazama. Her investigations reveal the Water of Life elixir (which creates Rasetsu) originates from Western demons’ blood, explaining its sunlight aversion and bloodlust effects. She is later abducted by Sanan and held captive in Sendai Castle, where he force-feeds her his blood to control her as a puppet ruler. After a rescue attempt, she temporarily falls under Sanan’s control and stabs Kimigiku—an act that shocks her back to autonomy. Post-rescue, she aids in locating a curative spring for Rasetsu effects and bids farewell to Chizuru and Heisuke.
In broader plotlines, she enforces demon laws forbidding direct involvement in human politics, pressuring Kazama to cease abducting Chizuru by threatening clan banishment. She confronts the Shinsengumi about Rasetsu attacks on civilians and reiterates protection offers to Chizuru, sharing ancestral stories of demons loving humans.
Her character draws historical inspiration from Tokugawa Senhime (1597–1666), daughter of Shōgun Tokugawa Hidetada, though her narrative role is fictional.
