After Bloody Roar faded into the ether, Eighting didn't give up on fighting games, they just started making licensed ones. Naruto: Clash of Ninja, Tatsunoko vs Capcom, MVC3, and as we can see here, The Mightiest Disciple Kenichi. It's actually about as faithful of an adaptation as you could ask for, and is surprisingly grounded in reality for a fighting game based on a shonen manga. It's slightly disappointing that you can't play as the masters, but it makes sense, and there's still a solid roster here including favorites like Valkyrie and Siegfried, not to mention Niijima as an unlockable.
A cool little bonus is an 8-page manga by series creator Syun Matsuena about his experience working on the game. For one, he apparently got the call from Capcom before talks of making an anime even started, and the voice cast was actually chosen for the game and kept for the TV series. Matsuena found out who the cast were after voice actor Tomokazu Seki called him one morning in character as Kenichi, confusing the hell out of him. It's also got an evil-looking Yoshinori Ono telling Matsuena "Panty shots are a no-go! Do you want to get an 18-rating?!", Matsuena begrudgingly agreeing to do a huge number of illustrations, and a picture of Renka with the caption "If there's a sequel, I might show up too!" Too bad that sequel never happened...
