Shun is one of Kuro's classmates and hands down one of the most talented artists around. He's got a real gift for making things—whatever he creates tends to be genuinely impressive.
The thing is, his home life is pretty rough. His father actively discourages him from making art, claiming that Shun's creations are upsetting his mother so much that she's ended up in the hospital. It's the kind of emotional pressure that would mess with anyone's head, especially a kid who's naturally talented at something.
Then there's the weird part: Shun deals with a bizarre condition where popcorn randomly pops out of his head. It's as strange as it sounds, and fans often note it as one of the series' more absurd and memorable details.
