Kinta's a student who regularly helps Momo and Okarun deal with paranormal stuff. He's one of their most dependable allies when things get weird.
Personality-wise, he's got a serious ego problem. He'll be dismissive toward guys his own age and acts like he's way above casual socializing with them. When Okarun and Jiji showed up at the Ayase house carrying the beaten Bamora, Kinta came out acting superior, immediately criticizing them for being late and completely brushing off any compliments they tried to give. He's also a massive attention-seeker—he actually showed up at school with an eyepatch and full bandages, spinning this whole story about winning a one-man battle against an alien. The whole thing was fake, obviously just to look important in front of Momo and the others.
He's constantly trying to seem cool and tough, making these over-the-top statements and striking dramatic poses. The problem is he can never admit when he messes up. Instead, he'll just come up with some excuse to save face.
With girls, it's a different kind of embarrassing. He wants to seem charming and romantic but completely misreads how relationships work. His perception of what guys and girls do around each other is just. off. He's also pretty perverted about it—he once got excited thinking he might kiss Momo when Bamora sent him flying toward her, and he wanted to rush through fighting the Spatial Exosuit Kur just so he could have some "lovey-dovey downtime" with Bamora.
