== Biography ==
Sinjin first appears in the pilot episode, working backstage during the big showcase and providing Tori with a headset. In later episodes, his quirky personality is highlighted through his unusual hobbies, awkward crushes, and bizarre antics. Some notable appearances include "The Bird Scene," where he shows Tori his locker; "Jade Dumps [[Beck Oliver|Beck]]," where he asks Jade if she wants a new boyfriend; and "Robarazzi," where he shares his collection of presidents' relatives' teeth, creeping out even [[Rex Powers|Rex]]. Sinjin is also involved in various other storylines, from almost drowning in a kiddie pool in "Survival of the Hottest" to sneaking into Jade's house in "Wi-Fi in the Sky."

He is frequently seen engaging in bizarre activities, such as dressing up in costumes, working backstage at Hollywood Arts, or causing trouble for his classmates in various ways. He also plays a saxophone in the girls' bathroom ("Crazy Ponnie"), helps produce Beck's film ("The Blonde Squad"), and gets involved in several mishaps that reflect his quirky and often unpredictable nature.

Throughout the series, Sinjin remains a memorable character due to his odd behavior, unique hobbies, and persistent efforts to befriend or date his female classmates, despite their lack of interest.
