This is how Pain met Rebeca , he was trying to summon a blood thirsty demon called The Nightmare . (The Nightmare is a beast that I made for my Gothic story , in sophomore year of high school , I've yet to redraw it and the other characters. )However he accidentally Rebeca a Blood Starved demon, but the instant after shes summoned shes drawn in by the panda look and imminently topples him just to see if their real . and that is how he ended up having the worst luck ever and still cant get rid of her!
