Aeon

Aeon is a 30 year old ex-assassin who works for the Shadow Syndicate. He was an assassin from the age of 20 up until he turned 29 which was when his husband convinced him to stop doing that work, out of fear of him getting killed while out in the field. His ability as an assassin was truly remarkable, being an expert marksman, but he didn't want to worry his husband any longer so he decided to retire.

Aeon currently works as Star's guardian while out of missions. This is due to Lumen's incredibly reckless behavior while out on his missions, which usually ends up in Lumen almost dying. Aeon personally took on this job due to him actually being good friends with Lumen's parents. It was because of him and his husband was how Star even landed the assassination job to begin with.

Aeon himself is a man that takes work seriously. He always keeps a stern face and a cold attitude when out with Lumen. This isn't because of any sort of hatred for the boy but is, in fact, meant to display to Lumen the type of attitude you should keep when doing this kind of work. He absolutely DOES hate Lumen's overly cocky attitude and uncanny skill of pissing people off, especially when Lumen does it on him. He does care for Lumen though and he owes to himself to make sure he at least walks out of his missions alive.

While he does care for his work, the only thing above that and all other things to him is his husband, Sebastian.
