Pyrolight said: Fanon - Sakuya wins for the story unless the author tosses in a twist.
Canon - Meiling more or less beats Sakuya to death with those rules.
Canon is something that no one knows or pays attention to. if this is non danmaku. Then she can stop time and stab meiling. If she cannot do that, 1 punch from a youkai, specially of the type of meiling should make sakuya's insides into gelatin.
