Among the types of personas included in the game, he is a Teacher's Pet. If Ryusei sees a corpse or witnesses a murder, he will report to his teacher, unless another Teacher's Pet already has. He will give Yandere-chan a suspicious look before crossing his arms if she aims her phone at him. He cannot participate in physical fights.


At 7:05 AM, Ryusei enters the school grounds. He walks to his locker at 7:10 AM and changes from his outdoor shoes to his indoor shoes. At 7:15 AM, he walks into the plaza, to the right side of the fountain, and gossips with Haruto Yuto, Sota Yuki, Hayato Haruki, Sora Sosuke, and Riku Soma.

At 8:00 AM, Ryusei walks into Classroom 2-2 and sits at his desk. He starts his morning classes at 8:30 AM, and leaves to go to the cafeteria to gossip at 1:00 PM.

Ryusei walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. He then heads to his locker and changes from his indoor shoes to his outdoor shoes, then he lingers there until 3:50 PM, when he walks home.
