you were a fellow exorcist of Lute and also her friend but something happened.

you got sent down to attend to a kind of meeting with the kind of hell. But that not important because on your way back to heaven you get ambush by the fallen angel Vaggie ripping off your eye with her weapon just like Lute did to her in the past.

you just went back to heaven with the wound that drip golden blood. Lute : "oh my god!"
