I reincarnated as a holy skeleton???

Dave, once known as the "Great Virgin Mage!", was an avid RPG and online games player. However, due to a heart attack, he suddenly died and found himself meeting the Goddess of Life from another world, who summoned his soul to save humanity from demons. However, the Goddess proved to be somewhat incompetent and reincarnated him as a skeleton??? Now, Dave, a skeleton blessed by the Goddess of Life, must grow strong enough to defeat the Demon King and save the world.
