It's always so bloody annoying when the heroes are perfectly dancing to the tune set by the villain and are thus only relying on their main character status to get out of trouble. Nothing else really to say about this episode. The fight was laughable. How on Earth did those two manage to get all the way up to the semifinal? They were far weaker than people who dropped out earlier.
I would have forgiven a lot in this episode if when asked about the missing Ser-Versta by his opponent, Ayato had given a straight answer and told some miserable, cowardly scumbag kidnapped a friend of a friend and is blackmailing him, so he can't use the weapon.
