Senpai

Senpai is a young man with light skin, a constant blush, strawberry blonde hair, and wide blue eyes. He wears a partially tucked-in periwinkle blue button-up shirt, a loose pink tie, grayish-purple jeans held up by a black belt with a silver buckle, and grayish-purple shoes. He carries a brown backpack in his right hand over his right shoulder and holds a pink microphone with a bluish-gray capsule loosely in his left hand with his thumb and index finger. In his idle animation, his head sparkles. Fitting his dating sim origins, he stands and stares forward in the player's direction instead of towards his opponent. Additionally, he is portrayed in an anime-esque pixel art style. Senpai is normally a very polite and calm individual who typically speaks in a formal way, especially towards people he likes. However, he has a short temper and is a sore loser, becoming rude and speaking more vulgarly after losing. This sudden behavior change is explained as a result of Senpai's programming being unable to handle a loss since he was only ever meant to be perfect.

Senpai has been described as a "generic pretty boy asshole" and is somewhat based on how people who are self-centered or toxic can be in real life.
