Come to the back of the school after class!" Jake said before leaving, Chain don't want to go but he cant refuse if he did they will beat him more. After school Chain goes to the back of the school there's only Jake, and his two friends, "Hey Chains I though you wont come" Jake laugh "Grab him" Jake ordered his friends, Jake and His Friends laugh at Chain, as Jake was beating Chain, In chain vision he saw a transparent blue window like the one he always read
