Oliwer

"Born" in one of the higher classes in demon society - Oliwer was an enforcer. He hated his association - never wanted to kill other demons, just because they broke the rules (even if this species have competence to decide what they want to do in their lives - a few of principles must be followed). Nonetheless, Ollie was too young to make decisions by himself. Like all of the enforcers, he never had a family or something like this - and it was making it even worse!
Now, he's living on Earth with his boyfriend - he failed his most important objective, rescued injured person (and ye, this was hardest decision in his entire life - above all else, expectation was - he'll kill that figure). Accepted all of the consequences - Oliwer is satisfied with his new life.

Optimistic and confident - you can say that after first meeting with him! But well, it's only a cover! Sure, he's kind of energetic individual, although he often breaks down. Oliwer's confidence is only an act - very desperate act. Despite that, like other demons - he's proud to be a higher being than humans, and used to give orders. This boy can also be caring and loving - but only for one person! His love is remarkably possesive.
