Negima!? Chou Mahora Taisen Chuu: Check-iin Zenin Shuugou! Yappari Onsen Kichaimashitaa

Class 3-A takes a hot spring trip for an unusual reason: Negi Springfield cannot stand baths, and the class wants to fix that. The trip goes sideways immediately — a monster appears and begins kidnapping students. Negi's own magic is sealed by the creature. With his power locked, he and the remaining students equip themselves with magic gear and fight their way toward whoever is responsible.
