The life with bones in another world

A man finds himself in a world similar to the MMO he was playing... but he's just a guard with no dialogue! Moreover, when he rolls for support classes at the Divine Blessing ceremony, he gets nerfed instead and is fired from his post?! Left indignant by this turn of events, ex-guard Nemo decides to become an adventurer and throws his whole self into researching the three "blessings" he did get: "Sculptor", "Alchemist" and "Necromancer". Maybe if he could combine the three, he could make a summonable skeleton familiar...?
