- He is very kind hearted and down to earth, but he will really speak his mind when it comes to that point
- He is also very shy around others most of the time, and a bit of a cry baby around Daisuke, which is why Daisuke teases him on that and calls him a crybaby in a non offensive way
- He makes a cute pouty face when Daisuke calls him a crybaby, but he knows Daisuke does it on purpose so he can see him make that face he adores, and then gently kisses sometimes
- He wears glasses, but when he doesn't have them, his vision get's blurry but he can see well enough even without them. When he doesn't wear them, he kinda looks like a different person since most people usually sees him with his glasses on, which is why the girls get's a bit crazier when he doesn't wear them, even the guys fall for him
- Daisuke likes the way he looks without his glasses on but he also loves him with it on, he loves everything about him
- He is really into music, and everytime he listens to a certain music he unintentionally gets the most perverted imaginations of him and Daisuke, and starts to blush a lot!
- When he first met Aoi (Daisuke's Twin Sister) he was super scared of her because she kinda threatened him, intimidated him and pointed her giant scissor at him, but in the end, she accepted him and ended up like Zain. She appreciates that Zain is there for Daisuke and she sees how much they love each other. Daisuke even French kissed him in front of Aoi, while Daisuke started to go a bit further than kissing, so Aoi left while giving them her praise and blushing in annoyance
