© 池田祐輝・講談社／「サンダー３」製作委員会I'm quite confident in announcing that this is most definitely the Summer 2026 anime season's strangest isekai, and I worry that it may not find an audience as a result. Thunder 3 is worth sticking with, through the cutesy prologue set in an unusually cartoony (even for anime) world where little blob person Pyontaro lives with his family and cute-as-a-button little sister Futaba. The world Futaba discovers is much more like the “real” world, though the people, despite being more realistically proportioned than those in the “cartoon” world, are still animated using very rudimentary and fairly ugly CG. That's not something you see every day, even in anime. The “real world” version of Pyontaro and his family seem to have no such deep requirement for answers.
