Shiro no Necromancer ~Shiryou Ou e no Michi~

After dying of sickness at 15, I had been reincarnated into the world of the MMORPG "War Chronicles of Desgarde"! The help feature taught me the basic summary of this world, but there seems to be additional secrets about me, aside from my reincarnation. Let's survive in this Isekai world to become the character I played in my previous life, a necromancer! (Wait, there's a Necromancer King? What's that?!)
