This is another first riichi mahjong speedrun (that I know of after extensive searching for anyone who has run this game before) featuring a game that may be even more obscure than Akagi!

This is the Capcom Kumite, or Capcom Side, or Capcom% (take your pick). It is the easier of the two sides in this game, as it allows you to continue from the same opponent you were on if you lose a round. (Psikyo can set you back several.) Definitely not a bad first stab at it. In the future I need to try not to tunnel-vision so much and keep an eye on the opponent's discards to make more calls.
