Greg heffley meets his favorite superhero and gained his quirk. His friends and family has a cool ability called quirks. 85% of the population has it while the 15% doesn't. He was bullied because he has no quirk.
After gaining his quirk, he went to an academy where you can be a superhero and his bestfriend is also there.

I don't own Diary of a wimpy kid and My hero academia. Credits belong to Jeff Kinney and Kohei Horikoshi. I own the plot but not the characters.
