Dandadan, Vol. 9 (manga)

A seemingly unbeatable kaiju is on the attack! Okarun hits on the idea of revisualizing the nanoskin that repaired Momo’s house into a form they can use to counterattack, but he lacks the visual abilities needed, so it’s Kinta Sakata - aka Erosuke - to the rescue! The nerd uses his vast knowledge of sci-fi to transform Momo’s house into… a giant Buddha robot?!
