Throughout most of the game, he functions as comic relief, and he is very lovable because he is easily the most friendly and optimistic crew member and tries to appease Swansea despite constant beratement. He is also selfless as he risked his own safety to save Curly and Anya from the Medical bay. However, his death is very tragic as he was fatally injured by the vent, forcing Swansea to put him out of his misery with an axe, but apart from this he is more lighthearted than the other elements of the game. https://hero.fandom.com/wiki/Daisuke_(Mouthwashing)
