Alright, so I should first try to explain what these guys even are. So obviously they all have bells, but they're basically these shrine spirits who have become sentient and use their bells as their weapon. Hopefully Google translate didn't screw me over with their names, but here's what their names are supposed to mean: they all have "beru" in their name which is Japanese for bell, then the first stage has "sukoshi" which means little, second stage has "Ōkī" which means big, and the final has "Kyojin" which means giant (giant is more for how big their bells are, they are literal giants themselves)
Hopefully that covers enough for these guys, if not just ask down in the comments. Credit to my artist I always commission @poketrainervb on Instagram, and I hope you like how this line turned out
