I see Kaito as a Vegeta-type of character.
He knows that Kouta is as strong or even stronger than he is, and while he finds him annoying, he also respects him and wants to be the one who takes him down in the end.
When he saved him from Zangetsu-Micchy, I could almost hear him say Vegeta's line: "No one kills Kazuraba Kouta while I'm around... Destiny has reserved that pleasure for me"
I find it interesting that they are holding back on a Gaim vs Baron fight.
I wonder if they want to save it for the final episodes.
Any thoughts on this?
