A nerd must fight powerful spirits and aliens all vying for the secret power of his “family jewel,” so who better to fight alongside him than his high school crush and a spirit granny?!

Erosuke—to the rescue! The nerd uses his vast knowledge of sci-fi to transform Momo’s house into…a giant Buddha robot?!
