This is ridiculous. Wasn't it mentioned that Rokan rank first in the game? And he's been overpowering every single opponent from the beginning including Nidhogg, and now for some reason he's been bested by 2 of Odin's dogs. If the author needs an introduction to this bishop girl, he should've done it differently. This is just sloppy and convenient for the sake of giving her a 'reason' to fight.
