I keep breaking my thumb no matter where I go and what I do, even Hentai Kamen can't help me anymore! WHAT SHOULD I DO?!

You're not calling Hentai Kamen the right way, he demands a certain kind of panties to ease your pain. As evident, he will come to you neverthless, but he's too nice of a guy to leave without trying to do something with his limited powers. It's like equal exchange except with underwear.
