Ryouji Matsubara  

, 松原 良治

Recently, Ryoji, also known as Ryo, moved to live with his uncle and his family, which includes his wife, Kasumi, and their daughter, Mio. Although he is not as close to Kasumi as before, they both understand each other well. However, Ryo's relationship with his uncle is more challenging due to the fact that his work often keeps him away from home. This could be why Ryo's uncle suggested living with them so that there would always be a male family member present who can take care of the two ladies. Despite this, Mio, the small million, adores Ryo and is almost constantly around him.
