Infinite Growth of the Chillest Hunter In The Tower
Zen was an orphan, a pretty regular one at that. His parents had been killed during a dungeon break when he was eight years old, and now ten years later he was still an unawakened that could play no part in avenging them.
However, he didn't let it get to him, his philosophy in life was to leave this sort of thing up to God, albeit he wasn't religious, but putting his responsibilities onto someone else's shoulders was much easier, even if they weren't real.
One day, while standing in a field, he awakens to his power and is summoned to a never-before-seen phenomenon, the Tower. With 100 floors to climb and the promise of safety for their world, the awakeners had no choice but to climb it, and Zen was no different.
