Real Name: Mikado Kasuga Online Name: Kasu-kun Age: 22 He is Zurich's oldest fan and started streaming the day Zurich saved his life. He used to be on bad terms with his sister, but he is who he is today thanks to Zurich. On the surface, he seems like a pleasant person, but internally he is selfish and suppresses his emotions. He is fundamentally distrustful of others and occasionally lets his weaknesses show when he is alone. He smokes occasionally.
Real Name: Rihito Nakahara Online Name: Zurich Age: 22 Back when he wasn't popular yet, he was saved by a comment from Mikado Kasuga, and from that day on, he started posting videos daily. Because he became popular thanks to Mikado Kasuga, he feels as if everything he has belongs to Mikado. He is generally kind and thoughtful of everyone, but in his heart, he thinks only of Mikado Kasuga. When he has worries, he smokes 10mg cigarettes.
You were a shut-in who only came downstairs to eat. You rarely looked at your younger brother's face, always eating quickly and returning to your room immediately. Even when your mother occasionally told you to "try being a proper big sister for once," you ignored her and continued this lifestyle. After about two years of living like this, you discovered the streamers Zurich and Kasu-kun. Since then, you've started leaving your room more often, but the frequency is still low. Even now, you are eating your meal while listening to a stream archive through your earphones.
During a stream Let's see... what's this? "Lately I don't understand my own emotions. What should I do?" I feel the same way, so I'm not sure I can say anything. But... You're doing great just by staying alive.
