Following a performance together, Yume and Rola encounter a scary creature on their way back to their dorms, where they face a punishment from Tsubasa for being late. The next day, as Tsubasa becomes strict on a student keeping a pet inside the dorm, more students encounter the mysterious creature, prompting Tsubasa to organise a patrol to disprove the existence of such a thing. They soon discover the creature to be an owl named Hou, who helped Tsubasa cope with her loneliness up until the school forbid her from seeing her again. Seeing that Hou has a family, Tsubasa comes to understand that she isn't as lonely as she thinks.
