Morita resides in room 203 and is shared by Takemoto and Hasegawa. Despite being unable to graduate due to missing classes, Morita has an undisclosed job that keeps him busy. When he returns from work, he falls asleep for at least two days, likely because of the demanding nature of his employment. Although his flat mates suspect he brings back food items as a form of mockery, such as when he presents them with croquettes instead of meat, Morita genuinely cares about his friends including Takemoto.
Morita is an enigmatic individual who enjoys engaging in peculiar and eccentric activities for personal enjoyment, like creating a Twister game with excessive colors which caused pain to himself and Takemoto. He possesses keen insight but can be blunt and truthful, such as disclosing Mayama's secret stalking of Rika despite the unwillingness of others to hear it. Additionally, Morita expresses his affection for Hagu in unique ways, like compelling her to dress up as a mouse. His fascination with Hagu stems from his childhood love of cute things which led him to make a cat neurotic by cuddling it excessively.
