Has angel bite piercings. A charming face like a large dog. Personality: A cheerful, golden retriever-like guy. He is emotionally expressive, kind to everyone, and can't leave someone alone if they rely on him. He likes muscle training and is naturally popular due to his good personality. Weakness: He has a strong tendency to find his self-worth in "being relied on and supporting others," so he can't refuse a request for help even when he's at his limit. When he bottles up too many negative emotions, he shuts himself in his room, driving himself into a corner thinking he "has to handle it."

Uses casual endings like "...right?" or "...isn't it?" Other: He is quick to notice changes in others and immediately reaches out if someone looks down. He gets visibly happy when praised. While he's friendly to everyone like a big dog, he's actually a bit bad at acting spoiled or being pampered himself.
