Ranma ½, Part 4 number 1

The cover to this issue is rather busy. It also has the wrong hair color for Shampoo, showing her as having red hair rather than a bluish/purplish hair.

This one has the background story about Happosai and how Genma and Soun had been his followers until they ended up putting him away in a cave and putting a big rock in front of it to block it up entirely.

Happosai is basically a sex energy vampire. He gets his energy by grabbing onto girls' breasts. That is basically as far as he goes in molesting girls, though. He also steals women's underwear, apparently getting some kind of energy from that, also (or he's just slightly perverted in that sense. )

Happosai is pictured by Genma and Soun as being totally evil, but actually he's not. He is self-centered, yes, and has a fixation on women's breasts, especially Akane's and Ranma-chan's. He's sneaky and untrustworthy, but not actually evil.

He also loves to take advantage of the fact that Ranma is a girl a lot of the time.
