If you didn't pick up on it while reading Chapter 4, future Shota was actually married to the adult Mai. Did you see that coming, that is the reason why I put that paragraph at the start, so that it would act as a misdirect. I wanted to make you think that Shota and Mai were still friends, and that Mai was married to someone like Renji, but then again, that would not really make sense. I mean, Renji? Also, what do you think of Mad Gallant as the main villain of the story? Do you like how Rainbow Hero and Solar Daybreak Hero have completely different colour schemes and weapons?
