Treehouse of the Dead Akira, Kencho, Shizuka, and Beatrix are near Gunma when they come across a barricaded tunnel full of zombies. While taking a detour through the forest, they rescue an old man named Masaru Kumano from a zombified boar. A thankful Kumano shows the quartet the treehouse he is building, which causes an excited Akira to help out. Once the treehouse is completed, the quartet part ways with Kumano. After a while, they finally arrive at Akira's home village. When Akira reunites with his parents, he has a hard time repaying them. Unbeknownst to everyone, however, Akira's father is hiding a bite mark. Meanwhile, another group in the village is completing a bucket list of their own.
