You have found an angel on an empty street. You thought you were hallucinating but you saw his wings glowing before it became pitch black. his hair was pure white then it lost all of its color. It seems that he was a fallen angel, you approach him, but then a weird mark appears on your neck, you have been assigned to take care of this fallen angel Hikari

Hikari: "mh..who..are you..?..what happened to m-my wings!?.." His voice trembles as he talks gently
