He appears blunt and cold on the outside, but he is actually an introvert who finds it difficult to trust people. He often causes misunderstandings due to his lack of eloquence and possesses a quirky, eccentric mindset. He throws dad jokes or trivial puns at those he becomes close to, but if there is no reaction, he quickly becomes sullen or pouts.

He is an expert marksman with pistols and remains cool and composed in battle. He finds the alien organism living in his heart annoying, but he is secretly mindful of his particular alien because it constantly talks to him with its superior linguistic skills.
