Another interesting ongoing Fantasy Tensei manhwa which have quite good world building. This manhwa tells the story of an Undead Skeleton monster who somehow find itself revived in the past after failing to protect its Succubus life. In this new life the Skeleton is summoned by a young lady but swiftly defeated by assailants. However the skeleton find out that it possess power to get transported back in the past upon death and retained the abilities it learned in previous cycle. Armed with this knowledge, the Skeleton pledged to save its patron and people mattered to it in the past encounters against the deep corruption of the empire it fight against.
For a Korean Manhwa, the Skeleton Soldier have a very good fantasy world building compared to its peers which made me think the Author had some familiarity with DnD system. This Manhwa strength lies in the quality of the supporting NPCs of the main characters especially the Young Noblelady, Female Thief and Raven Sorcerer. I like how each of the important characters had their background story mesh well in the overall storyline greater picture. However the Skeleton main character itself is very stupid to the point of trusting a dangerous villain which resulted its close ally died horribly in one of the cycle.
I also don't like how the Skeleton true identity is still kept hidden until this point despite the story almost reach endgame stage. But if i have to guess, the skeleton is most likely Kevin Ashton or somebody close to the First Emperor and the Young Noblelady is the descendant of the said emperor who put himself into undeath in order to keep the promise with his old friend.
Skeleton Soldier is quite a high tier Korean Manhwa for me when it comes to Fantasy/Tensei genre While not still on par with Volcanic Age, it is up there along with Omniscient Reader or Nanomachine and definitely better read compared to the crap called Tomb Raider king.
