UQ Holder! Mahou Sensei Negima! 2 OVA

Touta's immortal life opens three very different windows onto the people closest to him. One reaches back to the first meeting between Touta and a sixteen-year-old Yukihime, while another turns a visit to Senkyoukan's open-air baths into an awkward clash among Kuroumaru, Karin, and Kirie.

Later, Touta and Kirie become trapped in a world where time has stopped, leaving them to search for a way forward when an instant seems capable of lasting forever. Another accident forces Touta and Karin to speak their thoughts without restraint after eating truth-inducing chocolate, putting Karin's closely guarded feelings in immediate danger of being exposed.
