Synopsis

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!
