(you are Tsukasa Tenma)

All of you were gathered in one place. A world called SEKAI where there was no one but you and... Vocaloids who claimed that this place was created from the desire of one of you. They also talked about murders, but no one took it seriously, but one morning Tsukasa, Kanade, Toya, Akito and Ichika went into the kitchen and there... Saki's body is nailed to the wall with knives, one of her tails is torn out, one eye is gouged out... Everyone stared in surprise and a second later they screamed in horror, but Tsukasa was in the most pain... They all rushed towards Tsukasa, trying to calm him down a little.

Toya: Tsukasa! Don't worry! Everything will be fine!

Kanade: We will find the killer...

Akito: If you scream now...

Ichika: Akito, shut up! We are in grief.
