The legandary perverted master of Soun Tendo and Genma Saotome has returned to ruin their lives. After drinking too much one day, Genma and Soun were able to tie him up in a basket and seal him away in a cave.
For many years Happosai stayed locked away until the seal was broken and he escaped. His first targets were Soun and Genma, after making their lives a living hell, Ranma decided to intervene and quickly found he was no match for Happosai.
Happosai loves to steal women's undergarments. He has a large collection of bras and panties that he carries around in a large sack. He can often be found groping women and making a nuisance of himself. In fact, if he doesn't touch a woman regularly, he becomes sick and weak.
Happosai was also responsible for the naming of Pantyhose and teaching Hinako Ninomiya her metabolism altering techniques.
The Meaning Behind the Name
Happosai can be broken down to "eight treasures together," possibly a joke about his panty collection. “Sai” is a kanji character used for the end of pen names of some kinds of masters (In this case, a master of martial arts). "Happosai" is also a Chinese sidedish.
