Sam

Sam is a tactical planner, a natural leader and excellent at critical thinking. Quinn and the whole Cursed Faction relies on Sam's ability to make decisions in hard scenarios with Quinn commenting that he wouldn't have been able to make choices as good as Sam. Sam does question his decisions in hindsight when things go wrong and blames himself for errors. When he is in a panic he over plans. Sam is kept busy dealing with the Cursed Faction that even when he finally has everything done he looks for more work believing that it can't all be done.

Sam's parents had originally spent a lot of money on ability books in the hope that Sam would provide benefits to them and be able to earn money. However, Sam reached his limit with the wind ability at level 5. Despite having a level 6 ability book he would feel pain trying to evolve his ability.

He was turned into a vampire in chapter 602. When the Cursed faction was created Sam became the main leader and decision maker of the faction with Quinn often performing other duties entirely. The control became so much that when the vampire leaders joined the Cursed Faction they were confused as to why the faction would have a weak person as such a leader.

When Quinn met with Logan for the first time after the time skip he explains that Sam went missing and nobody knows what happened to him and that it was the indicator that something was wrong and the system got out of hand. The cursed faction lost hope, and understanding of their goals and fell apart.It was later revealed that Sam had secretly joined Bliss
