At the end of chapter 59, we find out that Hirokazu has been shopping with his friends. He's wearing a little girl's underwear, which is a big deal because Hirokaz is trying to seduce a girl named Aka. Aka is all, "Oh, I'm not going to wear little girl underwear anymore. I'll just wear a little boy's underpants." Aka's like, "Dude, I don't think you're going to check me every time I go to your house. I just want to be totally fine." Hirokaze's all "Fine, you'll be fine" . Then she starts wearing the little girl underpants again. This time, she's totally grossed out by them. She's even more grossed out when she realizes that they're the only pair of underpants that she can wear. She can't even take them off, because she hates them so much that she wants to kill herself with them.
