Some recent series embodying the "Isekai Harem Monogatari New" spirit include:
The protagonist, a former Amazon logistics manager, is reincarnated as a ruined Baron. He has no cheat sword or magic affinity. Instead, he optimizes the delivery of potions and grain. His "harem" consists of a disgraced knight, a witch whose magic only works on preservation (cold storage), and a beast-girl cartographer. The story focuses on infrastructure and romantic tension born of mutual respect rather than accidental groping. isekai harem monogatari new
