Reanette happens to be an elite adventurer of the legendary party Orichalcum Fist, whose members welcome Rick under the condition that he follow a Spartan training.
Two years later, Rick is finally ready to take the E-Rank exam officially qualifying him as an adventurer. However, raw magical power can only be developed until one turns 20. As such, Rick faces the general hostility of fellow participants and examiners alike, leaving him no choice but to show the world that his hellish training has turned him into an invincible warrior.
