tentra the gate keeper (Patreon)

edit: added something

where dungeon incorporated exists to manage and control dungeons, this guy applied for a corporate job, ended up being given final boss profession. however once he saw his paycheck and benefits, he accepted his situation.  his only job is to guard the end of the dungeon, where the reward is.  humans come to try to conquer the place but is thwarted by him at the very end. since he doesn't like to hurt people, he simply throws them out.

people eventually come to just meet him and NOT for the reward. hes surprisingly strong and impossible to kill lol, but he has a very sweet personality.

besides guarding he spends his time reading in the secret library stocked with fanfiction and ancient texts with nothing distinguishing the two.
