Kono Boukensha, Jinruishi Saikyou desu: Hazure Skill "Kantei" ga "Keishou" ni Kakusei shita node, Amata no Eiyuu-tachi no Chikara wo Uketsugi Musou suru

Lacking any combat skills, Eustus was just another adventurer stuck at the bottom. That is, until the day his life changed forever when he awakened "Inheritance," the power to gain the memories and abilities of anyone, simply by touching something they once owned! He starts by tapping into the legacies of the heroes who once saved the world: the unmatched Sword Saint, the far-seeing Archer, the god-speed Lancer, the miracle-working Saintess, and the prodigy Archmage... inheriting their very lives and skills! With the strength and spirit of legends flowing through him, Eustus's journey from zero to the strongest in history begins!
