Tada no Shikabane no You dato Iwarete Ikuseisou, Kizuitara Saikyou no Undead ni Natteta  

After Spending Hundreds of Years as a Common Undead, I’ve Become The Strongest Undead When I Woke up

In his childhood, Zion had long been fascinated by tales of adventure and had yearned for more than his mundane life in a small town could offer. To achieve this goal, he left home and made his way to the city. There, he was able to rise rapidly through the ranks until he met with misfortune in a dungeon beyond his skill level. As he lay dying, his blood mixed with that of a fallen dragon, which would forever change him into an undead being. Despite being feared by humans for their lack of self-control and vile nature, Zion retained his memories and personality from before. He wielded immense power but lacked the will to use it. Driven by the desire to end his own life, Zion embarked on a journey through an unfamiliar world, encountering corrupt necromancers and all-powerful dragons along the way. Yet, despite their attempts, none were able to harm him.
