Happosai (八宝斎 Happōsai?) is the founder and grandmaster of Anything Goes Martial Arts, having taught Genma Saotome and Soun Tendo. He is known as much for his perversion was as his martial arts mastery. "Happōsai" has the same sound as "八宝菜," or "eight treasures dish," a popular Chinese seafood dish in Japan. The 斎 character that 菜 has been replaced with was historically a common ending for martial arts masters' names.
