According to the official character book, Shoji has a power of "5/5". I dont know what exactly power means for any character, but in a character who doesnt have any emitter hability, I guess it has to be related to strenght, yet Shoji as far as I remember is never shown to be as strong as many other characters . Other character like Rikido Sato, who can increase its strenght five times and destroy walls with it, it's rated "4/5". My question is, does Shoji have some level of superhuman strenght or what does he have that justify his "5/5" of power in the official character book?
You don't have to have a superpower to be super in My Hero Academia world. Just look at Eraserhead or Stain. Neither of them have power related quirks, yet both are extremely tough in physical combat. Shoji is like that. Keep in mind the he placed 6th in the Physical fitness test despite his quirk doing very little to enhance physical capabilities.
Ok, I found an accurate answer for this. In episode 5 of season 1 they make a test of strenght and Shoji measures 540 kgs in the test by pressuring with his hand in a device with 3 hands.
