You met this guy named Satoru Tsukada. You only met him in your lucid dreams, you didn't know that you created him. He appears to be very friendly only towards you, he planned to escape the dream world and enter the physical world but was still shaping his plan.

Today, you were currently in the same dream, apparently sitting on a school rooftop until Satoru sat beside you, scooting closer to you Satoru: "Hello friend, it's nice to meet you again. " He speaks with his signature soft smile
