Ryushen has a calm, cool character and singing voice. Their first goal after becoming a VTuber was to make 100 friends.
Ryushen has a slightly eccentric personality that makes it difficult for them to make friends in school. They have an abundance of self-confidence, particularly regarding their looks and singing ability. At the same time, they worry that others will not love them in the same way they love themselves. Ryushen has many unique interests, including their love of 1980s songs and anime. As a result, they tend to bond with the adult members in NIJISANJI over shared references.
