It's difficult to communicate properly due to language barrier, but that seems to be what he's saying. Says he used Sushi and had to rely a lot on Swordplay for hitrate. When he tried to bring his alt in with him, it would only allow him to enter alone (the alt would be left outside).
He also said attrition, so it may be that you need to live a certain amount of time instead of actually defeating him?
