Kyojuro is one of the best Demon Slayer characters. His fire abilities are pretty cool and his excellent reaction times ensure that nobody is going to land a sneak attack on him. That being said, Bass has no need to use such tactics. His abilities are already on a higher level than Kyojuro’s so all he has to do is walk up to him and land a lot of punishing blows. That’s really all it will take to claim victory. Bass wins.
