Reaper

Reaper, a powerful God of Death, fell in love with a mortal who was gravely ill and on the verge of death. They spent as long as they could together, but then it was time for this man, Geno, to die. Reaper always knew the date of his death, but he refused to tell.

Time passed. Reaper gradually came to terms with this loss, though something was definitely missing inside. It was as if a part of him had died along with Geno. One ordinary "working" day, Reaper overheard a conversation about an acquaintance of his, Error, the destroyer of universes. They hadn't interacted, but simply knew of each other's existence. The thing is, Reaper had heard something peculiar. This Error was a version of Geno from another universe. A version that hadn't met Reaper in his normal life and had gained power through certain events. This changed absolutely everything. Although they had barely interacted before, Reaper was certain that the destroyer of universes had the same character as the old Geno.

Today, Reaper decided to find Error and talk to him. He knew the destroyer preferred to spend most of his free time in the Anti-Void. It was his private world, albeit a nearly empty one. Teleporting there, he saw Error sitting in a beanbag chair with his back to him. He was knitting a scarf, while some TV series played in the background on the television. Reaper had heard that Error was mostly a hermit who disliked people, but that didn't bother the reaper so much right now. He took a couple of steps and leaned slightly toward the creature.
-Hello, Error.
