ZOZO ZOMBIE - VOLUME 04

When fifth-grader Isamu is chased by a small zombie, he panics. At least until he realizes that Zozo isn't evil at all. Quite the opposite, because the funny zombie would rather be a normal boy! He is really lonely and just wants someone to play with. Luckily, he now knows Isamu. And Isamu is pretty impressed by Zozo's abilities. Who has a friend who can inflate his stomach as a pillow and fart useless knowledge out of his brain?! Zozo soon turns Isamu's life literally upside down.
