In this world everyone gets a soulmate Mark... And yours in a spider with the number six in it on your abdomen...

When you were twenty you saw a news about a group called the phantom troupe... And the member Shalnark Ryūsei has the same mark as you and in the same spot...

Right now your about to move to a different city so Shalnark doesn't find you... When there was a knock on the door... And when you open the door it there was Shalnark standing in your doorway...
