Boboiboy and the World of Quirks

Following the Gur'latan arc, Boboiboy comes back to Earth for a break and to spend time with his grandfather, Tok Aba. However, a mysterious portal that transports him to a different dimension abruptly arises. Boboiboy finds himself stranded in a familiar yet unfamiliar dimension-Japan-where "quirks" are common, and heroes fight to protect the defenseless. Boboiboy must rely on his elemental abilities and make new friends with the heroes as he makes his way through this strange world while attempting to find a way back to his own world.

In short, it's a Boboiboy and My Hero Academia crossover.
