He was Model 72 — a crash test dummy. A being of metal and sensors whose sole purpose was to break and to be repaired. Routine crashes, routine analysis, routine repairs. Until one day, something… went wrong. Or maybe right. Now, he wakes up in Telaria, a unique world of magic and monsters, and in a body that is, for all intents and purposes, terribly inefficient.Soft flesh. Brittle bones. And as if he weren't fragile enough already, it all came gift-wrapped with something new.Pain.Every jab, scratch, and burn is a revelation. And strangely... irritating.But Axel is no ordinary human. Hidden beneath his supposedly fragile exterior is a regenerative gift so powerful that each recovery doesn’t simply restore him to his former state.It adapts his body against the very damage it just endured.[Your hand has been impaled by Crystal-Blade Grass.][Host's [Pierce Resistance] has increased slightly.][All leg bones have been broken by the ground][Host's [Impact Resistance] has increased greatly : x6][Your face has been burnt by a Fireball.][Host's [Fire Resistance] has increased greatly: x2]He hates it. Every injury is just another reminder that his human body is flawed.And yet he knows...his body can learn. His body can evolve.So, Pain?Pain is a problem he intends to solve.

No need for regeneration.”“I will simply be unharmable.”The world believes SSS Rank Gifts are the ceiling. The End-All, Be-All.Well...The world hasn't met Axel.
