I love touhou and all...but Yamamoto could beat Youmu in a sword fight. Maybe not in a danmaku battle...no wait yea he could just slow the bullets down. Yea Yamamoto could beat Youmu.
But I want to see a pick with him and Sakuya for some reason.
I wouldnt mind seeing a fight between Hyper mode Tsunayoshi and Mokou myself. I think i'd be pretty even between Yamamoto and Youmu. It depends if we're talking pure swordsmanship or if Yamamoto's is gonna use box weapons and Youmu is going to use danmaku to supplement their sword fighting.
