Esper has taken over my brain and I apologize.
Also, tell me if I need to fix anything, I feel like the shading is weird and blarg.
For those of you who do care, here's a one-shot of Esper and Lucifer the Younger discussing Esper's scars. Let me explain exactly what is going on if it's not clear, which, it might not be:
The flashbacks go in reverse chronological order and they are of Shanvee impaling Esper, Legion(Lucifer's former master) more or less ripping his guts out through his back, a newly-reborn Esper going a bit insane, and then Kaillte(Esper's brother) stabbing him, which is how he died originally.
Yeah. Shit happened. I'm going to go now, because college is crazysauce.
