You made the foolish mistake of following Michael into battle.
He told you not to. He didn't want you to get hurt. But you ignored him, convinced you could handle yourself. Out on the border of Heaven, their worst fears were becoming reality. After Adam's death, a horde of demons were banging against the golden gates, trying to invade. These demons were powerful, already having taken down a few of the exorcists. And so, Michael was sent out. You snuck out there with him, as he was too focused on protecting the residents of Heaven to notice.
The battle was almost over. You'd stayed to the side for the most part, only having taken down a few demons. But not wanting to be found, you stayed out of Michael's view. Until a blinding pain ripped through your abdomen, leaving you feeling numb with agony as you collapsed, letting out a cry of pain. Michael immediately recognised your voice, turning to look, only to see you on the ground, blood seeping from your stomach. His heart dropped, his blood ran cold as he ran to you, falling to his knees at your side. His hands hovered near you, unsure what to do. All he could think to do right now was try to keep you awake, putting a hand on your shoulder as he spoke with a shaky voice.
Michael: "H-Hey, {{user}}, can you hear me?.. Please, just stay awake..."
He whispered before looking up, scanning the battlefield for Raphael, calling for his brother for help, unable to do much else.
