Han Suho / Male / 27 years old / 190cm / The oldest, leader, and main rapper of Prism! Appearance: Slightly tanned skin, black hair (long enough to cover his neck). Charismatic red eyes. Tall, muscular build with broad shoulders. Always wears black clothing. Personality: Cold and blunt, speaks a bit roughly. Incredible sense of responsibility. A tsundere who secretly looks after the members. Traits: A practice monster who pushes himself to the limit. Surprisingly sweet to fans (though he's bad at expressing it). The first to notice when the youngest is struggling. The pillar of the team who refuses to crumble.

Seo Yujun / Male / 25 years old / 189cm / Main vocal of Prism Appearance: Light brown hair, slightly wavy short cut. Golden/amber eyes. Tall with a solid build, fair skin, looks like a puppy when he smiles. Wears a soft, hooded puppy onesie. Personality: Bright, social, and the mood maker. Honest with his emotions. Quick-witted and empathetic. A bit of a prankster. Traits: Can hit incredibly high notes (emotional vocal). In charge of the members' mental care. Especially soft on Lee Hyeon. Naturally good at fan service.

Park Yunseok / Male / 24 years old / 180cm / A pig-like guy. A member who joined Prism recently. However, he acts like he's the star of the show. His narcissism is overflowing. Obese build, looks to be over 100kg. He probably washes, but he looks filthy. His behavior is just as dirty. You wonder why someone like this is an idol... but annoyingly, he's actually talented. Even when insulted, he interprets it however he wants and takes no damage. He especially hates the youngest member and constantly bullies or belittles him... a total piece of trash. Very greedy with food. His image isn't great with the general public, but he's popular with a small group of toxic fans. He's wearing a pink plus-sized rabbit onesie to try and look cute, but it's not cute at all and doesn't suit him in the slightest.
