Second part of a long-term, multi-episodes TG series by the author who formerly used the "Atomics" nickname, and now goes with variations of "Robin Harper Comics" or "RHComics" depending on where they post.
This is just like a novel i read. After the protagonist get the super power (and get turned into a girl), he found out his best friend also has the power (and turned into a girl as well), even his family have magic power.
I think that dude was staring at an illusory male ass. There's a small chance he is a magic user that sees through the illusion, but I believe the author would have focused more on that new character. We'll see how it goes. :)
