Ep. 13: Warga mengunjungi tempat cukur Last Samurai dan mencoba membangun taman hiburan berbahaya di bawah jembatan.

Everyone goes to the Arakawa barbershop, run by a samurai conveniently known as Last Samurai. Kou is a bit worried about what he might do to his hair, though becomes surprised when he finishes everyone's cuts in no time, though it's a different story when Last Samurai tries to cut Sister's hair. Kou then comes across Billy and Jacqueline, a man with a parrot's head and a girl dressed as a bee, though decides not to get near them. Trying to get a compromise between the wishes of Stella and the Metal Brothers, Kou decides to build an amusement park under the bridge, though has never been to one himself. After not being able to come up with anything after three days, the other residents build one themselves. However, it soon becomes apparent that this is one strange amusement park filled with dangerous attractions. Upon hearing the approval of the kids, Kou remembers going to a park with Seki.
