Roman

Roman is a Hunter, and one of the series' best Demon Hunters.

Backstory
At a young age, Roman's mother was possessed by a demon, who then incapacitated his father and proceeded to chase Roman, only to be exorcised by Ryan Sharpwood after a brief but brutal fight. After saving Roman and his family, Ryan took Roman in and after telling him about the supernatural, started training Roman to be the best at doing one thing: hunting and killing Demons.

Throughout Hallows
Roman is hunting a Tickle Demon that's currently tickling a woman named Sarah, who is another Hunter who was sent after the Tickle Demon, but was caught. Roman comes across the Tickle Demon and attacks it, but is knocked out and tied to a table. The Tickle Demon than tickles him, forcing Sarah to watch helplessly as Roman breaks from the unbearable torture and passes out. The Tickle Demon then tickles Sarah to death.

Roman wakes up, horrified to see Sarah's dead body as the demon leaves, smiling teasingly at Roman for failing to save his friend.

Ever since that day, Roman has started to obsessively hunt Demons out of revenge for what happened to Sarah.

Personality
Before Sarah was killed, Roman took his duties as a Hunter very seriously, and was always intent on keeping all Hunters alive.

Nowadays, Roman is traumatized by Sarah's agonizing death, worsened by the fact that he was unconscious while she screamed in agony as the Tickle Demon broke her and then tickled her to her last breath.

Appearance
Roman is a very handsome and tall young man, with sleek brown hair and light green eyes. He has a muscular and athletic build, which comes in handy when hunting and fighting demons.
