Chuck Beans

Shosuke is a high schooler who’s bad at studying, sports, and almost everything else… But one day, a robot from the future called Chuck Beans shows up to change his life! Sounds like the cliched beginning to a stereotypical story, but Shosuke simply refuses him entry into his house! Tsurun Hatomune presents an offbeat slice-of-life sci-fi gag manga!
