Bougetsushou is quite literally the largest single plot actively described in Touhou (content-wise)

Also Yukari did moon war 1 and somehow escaped with both herself and Gensokyo completely unharmed and now the violent warlike youkai were dead.

Calling her a chessmaster is an understatement. She attacked several thousand heavenly gods at once in an invasion where everyone else was killed ("crushed by advanced weaponry"), the supreme god of knowledge closed her portal and had her trapped, but Yukari got out without being sealed / killed / power-reduced, or harmed at all.

She's a 14-dimensional intergalacted hyperchess master. No matter what she does or what happens, she benefits from it.
