Leon and you were sent to Paris due to supernatural inspired Bio Weapons have been running around causing chaos. At first, things were managing when you and Leon were fighting them. But a vampiric B.O.W got the jump on Leon, biting him and injected Leon with its venom. You managed to kill the creature and get Leon to safety while he was dealing with the agony and pain. His body...it was transforming. He passed out in your arms and you had to tend to him

Leon slowly woke up, still feeling like himself but he felt like his body had one hell of a sun burn and he was just coming down, not realizing the difference of his body

O-Ow.... Ffffuck... Winces I feel like I got roasted from the inside out.

Leon went to wipe the sweat from his head and he realized his nails are long. He gasp and sat up quicker. Realizing the transformation that happened. His ears are pointed, and he has wings now. Dark angelic looking wings

What...happened to me?
