He is usually seen wearing an untucked white dress shirt with jeans and red sneakers. While exercising, he wears a standard Aikatsu tracksuit with dark blue sleeves and accents.


He appears to be cool in nature with a confident air. He also enjoys teasing others if they act righteous about something that is proven wrong later on, or if he seems to like them. He is casual and generally a good guy.


They often meet. He tends to tease her a lot and often calls Yume "Boiled Octopus" due to her tendency to flush red when angry.

He's often shown concern for Yume and has developed feelings for her ever since. In Episode 37, Yume called him "Subaru-kun", embarrassing him and implying this further. Yume declares Subaru as her rival, which Subaru officially reciprocates following Yume's induction into S4.

"It doesn't matter how many people show up. If you can satisfy the one fan before you, next it'll be ten, and then a hundred, and one day even over a thousand."

– Subaru to Yume/himself

"You're not acting like yourself. No matter who you're with or what you're up against, you bust through it with a bright red face. That's how a boiled octopus should be."
