Skeleton Knight in Another World Season 2

One day, a gamer played video games until he fell asleep…and when he woke up, he found himself in the game world–as a skeleton! Equipped with the powerful weapons and armor of his avatar but stuck with its frightening skeletal appearance, Arc has to find a place for himself in this new, fantastical land. All his hopes for a quiet life are dashed when he crosses paths with a beautiful elven warrior, setting him on a journey full of conflict and adventure.

Getting isekai’d to a magical world and developing incredible powers is every otaku’s wildest dream, but for salaryman Yuuji Sano, it’s the stuff of absolute nightmare! He’s in the middle of a mountain of work when he gets unwillingly pulled into a fantasy realm, where he accomplishes the enviable feat of developing a second character class by making the most of his Monster Tamer abilities. Now he’s traded the office for adventuring to make a living, but he keeps getting roped into major events because his powers are unmatched, second to none — and he doesn't even realize it yet!
