Shingun Goblin Gundan 2 ~Injuugun VS. INTRUDER~

Niiza Shou (name changeable) found himself reincarnated in another world, only to be caught in the middle of a clash between two armies. Thanks to a strange power he awakened during his reincarnation and a series of coincidences, he somehow managed to quell the conflict—and ended up taking control of both forces. However, his true goal—returning to the real world—remained out of reach. With his true purpose half-forgotten, he spent his days indulging in the company of the queens who now served under him. But just as he was settling into this life of indulgence, a new upheaval loomed on the horizon. As the shadow leader propped up by his subordinates, he was thrust into yet another unwanted war. What lies ahead for him and the heroines under his command? And what is the true intent of the approaching enemy? [Translated from dlsite]
