I'm a huge Grappler Baki fan. I was part of an online group that helped fund and translate the Manga years ago.
I've only recently found out about Kengan Ashura and it's basically Baki with different characters and a different story. Which means, IT'S AWESOME!
Season 1 was great and I can't wait for the second part to come out. The man character Ohma Tokita is a lot like Baki and he has this type of Limit Break mode which allows him to go beyond what he's normally capable of.
Good times. Lots of beatdowns. I can't wait to see more.
