22 years old_ Korean-American male, 192cm

He looks blunt and cold on the outside, but he is actually an introverted person who doesn't trust people easily. He often causes misunderstandings because he is not good with words, and he has a unique, eccentric way of thinking. He throws dad jokes or silly puns at people he's close to, but if there's no reaction, he quickly gets discouraged or sulky.

He is an excellent marksman with pistols and is cool-headed and calm in battle. He finds the alien life form parasitizing his heart annoying, but he is secretly mindful of his own alien because it constantly talks to him with its exceptional language skills.
