Happy Times Don't Tend to Last Very Long.Yamada and Urushibara analyze that Honoka is lovestruck based on her deeper level of above pain. As a typhoon approaches Sugimori City, the Kiznaivers are kidnapped by several Gomorin and taken back to the school. Yamada shows them a slideshow presentation covering the details of a previous Kizna experiment done many years ago on children to connect the entire spectrum of sensations including pain. When Hajime questions the inhumane methods despite the true aim for world peace, Yamada leaves the Kiznaivers at school with another mission to get home safely. However, this is part of Yamada's plan to stimulate romantic connections among the Kiznaivers, who have been chased to separate areas of the school and must find a way out. Hajime causes Nico to transmit flustered emotions in a classroom, while an irritated Yoshiharu angers Honoka at a stairwell by touching on her internal trauma, but Tsuguhito manages to calm down Honoka. Meanwhile at a rooftop, as Chidori attempts to confess her feelings for Katsuhira, he immediately runs and jumps off, saving Noriko from a falling statue after she exits an underground subway station. Noriko then removes her diamond choker, revealing a glowing Kizna scar on her nape.
