Shiro no Necromancer - Shiryou Ou e no Michi

After dying of illness at the age of fifteen, I was reborn inside the world of the MMORPG War Chronicles of Desgarde! The tutorial function taught me the basics of this world, but apparently, there are hidden secrets about my existence beyond just reincarnation. In order to become the necromancer I once played in my previous life, I’ll survive in this dangerous isekai world step by step! (...Wait, there’s a Necromancer King? What even is that?!)
