[@BurningDaisies]My character is hopefully going to be a Devilslayer, learned hius magic from his mother, who ended up turning into a Demon and trying to activate this change in her son as well(hewas around ten-ish when it happened), cutting off his arm in the process. He was saved by a Cloud Chaser mage and has been with them ever since. His arm got replaced by a robotic prosthetic that helps him with his secondary magic, which I'm planning to be some form of illusion magic. Not sure how yet.

Personality is not set in stone, but his current motivation is to find his mother and help turn her back from the insanity she's currently found herself in, while also being terrified of becoming that way himself. I'm thinking he uses illusion magic to hide his true feelings, similar to the one guy in Kagerou Days(if you've heard of that anime), making him appearto be a more happy-go-lucky guy then he is, but still not sure about it yet. 

For possible connections, Rhett could've saved him with Spatial magic to getthem both the hell out of dodge(depends on age though, as my guy is currently 19) while with Nemu, they could be good friends perhaps have a sort of sibling-esque relationship? My slayer constantly being on the lopk out for Nemu in ordsr to keep them out of as much trouble as possible.
