Even though Haruto is the MC and obviously naturally buff, even he works out, though it might not be the way you think it may be. If you were to ask him what he's work out routine is, he'll most likely say that he rides his bike around town in order to be in shape. Even if that is half true, the real reason why he stays fit is because he is constantly running away from danger. Ever since he was a kid, Haruto has always gotten in horrible situations and when he it comes to choosing fight or flight, he usually flies out of of there. This happened so much that not only does that keeps Haruto vigorous, but it also made Haruto insanely fast!
