This is the unofficial sequel/alternate ending to You're just so pretty in your pain by Muffinsama. I don't exactly have permission to continue and start this story. But I can't not. My pain is too great and I need to somehow make it better myself. So let's make it better, shall we?
...
It was almost too late when Shizuo found him, and it looked like he was. The raven was lying there, naked, bruised, and bleeding. A gunshot wound on his thigh still running with blood pouring out profusely. Some white, sticky substance was caked onto his skin and was dried in his black locks. More red trickling out of multiple wounds on his back and trailing gracefully down his spine. A singe mark on his inner thigh. Purple, ugly bruises dotted all over him, he looked like he was a painted canvas. Painted with pain, and yet he lay there so peacefully, his eyes shut.
The blonde stood and stared in shock for a moment, the flea was hardly even recognizable at this point. His trademark jacket lay next to him, bloodied as well. The only thing illuminating the warehouse at this point was his flashlight. Dread filled the debt collector, settling in the pit of his stomach. He couldn't tell if the flea would make it through the night.
"Dammit flea, look at what you've done to yourself..." Shizuo hated the worry laced in his voice. He pulled out his phone, flipping it open, and called Shinra automatically. His hands were shaking slightly as he waited for the doctor to pick up, listening impatiently to the dial tone. Fear that the flea's life would be lost poured more adrenaline into his veins. But the fury and anger was even more powerful. Shizuo had to restrain himself from punching the wall or something. He had better uses for his strength.
"What is it, Shizuo?" Shinra's voice was somewhat husky, like he had just woken up. It would only make sense, considering it was past midnight.
"The flea. Hurt badly, I don't know if he's even breathing, Shinra. Be expecting me and get ready because I'm on my way now." He hung up without waiting for a reply. Shinra would understand the seriousness of the situation.
He picked up the flea without hesitation, using the blood coated jacket to cover him up. One might think it was for the better that Shizuo didn't see the gruesome bloodstains splattered all over the wall across from where they were. It was just more evidence of what had happened in his absence. Shizuo was glad for the darkness that shrouded Ikebukuro at night. He didn't need any questions. For some odd reason, he was truly worried about him. About Izaya. His mortal enemy. Shizuo never thought there would be a day where he would actually feel so scared for him, but this night proved him wrong.
In fact, he wanted to kill whoever did this to the flea. Cause them to die a thousand deaths. Make them feel a million more times than all of the pain Izaya had suffered because of them. No one deserved this. Not even the flea. Shizuo knew in his gut that this had been going on for a long time before the informant had come to Shinra the first time.
And that gave him more resolve than anything else. He was going to find who did this. And they were going to pay. Not in money, this was so different than his life as a debt collector. This was something new. He swore under his breath. There was no way he'd let whoever did this get away with it. Last time he had, and now the blonde regretted it greatly. Felt remorse for letting the dumb flea leave. Shizuo growled as he ran through the streets, darting around corners and jumping across rooftops, his parkour skills coming into use as his vision turned red.
...
The door was already open when he arrived. At least this time they didn't have to fight Izaya to get him treated. But this time was much worse than the last; the wounds were clearly more severe and they had been festering for at least a few hours. Celty had already prepared the guest room, and Shinra had gotten IVs ready, his first aid kit opened. Shiner refused to let surprise show on his face at how beaten up the poor man was. Instead he went straight to work, having Shizuo lay him out on the bed.
"I can't say if he'll wake up or not, but he's a very lucky man if he does," the doctor stated, hurriedly patching him up. Cleaning the wounds, applying ointment, wrapping him in bandages, the night was long and exhausting for them all. And in the end, they didn't even know if the raven would wake up.
