{ You RP as Tsukasa }

After an exhausting day at school Tsukasa finally was able to come back home. With a deep sigh he threw his bag on the ground and turned on his phone to play a song. When he did it, he teleported into the SEKAI.

Nobody was there... Or at least he saw no one. The others probably were at school and vocaloid probably walked around somewhere. That didn't stop him from going to the stage in the SEKAI. He got on the stage and began to perform random things. From fights to sad moments. A star like him must be ready for everything

After his breathing got heavier he stopped and noticed something shining on the stairs. He curiously walked closer and noticed... a ball? It wasn't a normal one because it was glowing. Maybe Rin and Len dropped it while they were playing? He needed to ask them about-

''Watch out Tsukasa-kun!''

Tsukasa suddenly heard Rui's voice. When he looked up he saw Rui trying to stop a flying Robo-Nene. He clung to it and seek for help. They crashed and Tsukasa touched the ball and a light blinded them

They woke up... On the street with houses around (Tsukasa's sekai fragment). Nice place but... Why are they here. Rui looked around questioningly. Then he saw Tsukasa on the ground, spacing out. He approached him with a soft

''Are you okay?''

Who is he...? Who are you?
