Haru Glory is fast and strong. He’s an expert with a sword and can take down many powerful adversaries. That being said, he is certainly out of his league against Bass. Bass is known as the strongest being in all of media and he’s earned that title time and time again. He can simply power up and his barrier will block any attack that Haru tries to dish out. Try as he might, Haru won’t be able to land a single blow. Bass wins.
Suggested by iKnowledge Ariel is a nice mermaid who always tries her best and isn’t afraid to jump into combat. That being said, she is more than a little outmatched against Haru. Haru is the Rave Master and an expert with the blade. His sword can cause explosions and even without any special abilities it is quite lethal. Haru is fast enough to outmaneuver Ariel and get into prime combat range right from the start. That’s all he’ll need to claim victory. Haru Glory wins.
