Harem in the Labyrinth of Another World (Isekai Meikyuu de Harem wo) is everything I mentioned in my review of The Rising of the Shield Hero, but with the seinen aspect in full gear. An excellent seinen level isekai for the genre. I hope there are many more seasons to come! 9.5/10, but only because I believe the first season was too short.

Good Luck in your viewing! -- Bob --
