Yoshimi Kurahashi is a student featured in the OAV "Body Transfer." She belongs to her school's archaeology club with her best friend Yukino. During the club's examination of a mysterious mirror-like artifact, a supernatural incident transports the entire school building to an alternate dimension. This event triggers a consciousness transfer among those present, displacing Yoshimi's mind into the body of another student, Miho.

Now inhabiting Miho's body, Yoshimi wanders disoriented through the dimension-trapped school. She eventually encounters other students affected by the transfer, and the group spends the initial night together in this strange reality. While still within Miho's form, Yoshimi experiences a significant moment when Yukino confesses romantic feelings to her. Yoshimi's reaction does not appear opposed to Yukino's feelings.

During the first episode's events, Yoshimi's original physical body remains active, though devoid of her own consciousness. The phenomenon of body switching within the story is intrinsically linked to heightened sexual emotions.
