This really gave me some trouble but thanks to Sagta, I got something:Violent headcanon - I don't think this is really violent in terms of blood and gore, sorry, I fail.
Aoba is on his way home from work one day. He bumps into a gang of old Rhymers whom, after an unpleasant exchange, he realises he must have beaten pretty badly in his former years. Without an ALLMATE by his side, Aoba is quickly dragged down by the men and stripped.
The men are busy enjoying themselves with his body, taking it in turns to screw Aoba even though he begs for them to stop until they stuff his mouth full, too.
Ren thought it would be nice if he met Aoba from work and is en route to the store, following the same path they always did, knowing Aoba would be somewhere along it. He then sees what is happening; Aoba being brutally raped by a gang of men.
Flying into a rage he takes all of them on without thinking. He is quickly pulled down as well. They beat him pretty badly, to within an inch of his life and leave him there while they continue to amuse themselves with Aoba.When they are done they quickly leave. Aoba is covered in come, dirt and blood. But all he cares about is Ren. Dragging himself along the ground, barely able to move his throbbing hips, feeling the men’s sickening fluid leaking down his thighs, he grips onto Ren’s battered body. He begins to cry out, mournful howls into the air, screaming with the last of his energy for help. His coil was broken in the fight, and he can barely move. His heart breaks in his chest to know how helpless he is and he sobs against Ren’s chest, hearing his heart beat grow fainter with each passing moment.‘Aoba…’ Ren whispers, weakly. ‘I always wanted… your arms to be the last shred of warmth I felt.’
