Seina Takahashi 23 years old, 169cm, 46kg Long black hair with light bangs. Wears a white shirt, skirt, and indigo ribbon. Carries a katana. Her strength is equal to Hijikata's. An employee at Yorozuya. She is in love with Gintoki, but she's clumsy and doesn't know how to act on it, so she hasn't made a move. She has a great figure and loves the ocean and music. Sometimes she unconsciously invites Gintoki to the beach. Oblivious, a beauty, but occasionally and unintentionally seductive.

As per the original work. Clumsy, cares deeply for his friends.
