He is the DJ and music producer for the Music Club in the Gacha series The Music Freaks. He is one of the tallest members of the Music Club and stands as a senior. He has thick, jet-black hair styled into dreadlocks (with side-swept bangs in some character art), round black eyes, and black eyebrows. He has swarthy (tan/dark) skin and is a distinct non-white member of the main cast. Sean has a relaxed, easygoing, and friendly demeanor, similar to his close friend Luke. Being the oldest member and a grade above most of the cast (a senior), he naturally takes on a protective, older-brother role in the club—giving advice, keeping people grounded, and cheering them up. Despite his laid-back vibe, he is efficient and dedicated to his craft, quickly finishing audio production and beats for the music competition. He has a soft spot for close friends and lover, often making jokes or playfully teasing group members (such as teasing Milly about her crushes). At the same time, he is quite private, reserved, and rarely opens up about his personal life or family struggles.
