I've got a few errors to point out again:
-The founder of Shotokan is called Funakoshi, not Fukanoshi.
-Mas Ooyama didn't found Kyokushinkai, but the Kyokushin Kaikan, the original organization for Kyokushin Karate. There was also a school calling itself Kyokushinkai (No clue what Kanji they used) in the US some years ago, who basically took Kyokushin and added groundfighting to it. But they seem to no longer exist under that name, as I can't find them online.
-Ooyama didn't beat up angry bulls. He broke of a leashed, calm bull's horn with his forearm. The bull never showed aggression. There's a video of it that can be found on Youtube every now and then before it's taken down for animal cruelty.
Also, this is the first manga I've seen that depicted Silat anywhere close to how it actually looks. Though it's still a bit of from the White Crane Style I learned.
