Happosai is the grandmaster and creator of Anything Goes Martial Arts. He is also a clinically evil, self-righteous and self-serving pervert who abuses all the untapped power that lies within his foot-tall wrinkled body. He has been alive for well over 400 years and shows no signs of nearing his end anytime soon. Being a martial arts master, Happosai has an unlimited artillery of techniques that he uses either to satisfy his own hedoism or bully others into doing what he wants them to do. For his unnatural age and size, Happosai can overcome an average person with seemingly no effort at all and unlike many of the antagonistic characters he often gets the last laugh in the end.
