........Alex is rather in-denial about the concept of harem. His perspective of this seems to stemmed from fiction genre. But reality have this you know? Though most of the times those harem are either a religious setting or precept of monarchy or traditional standards. The concept of harem that what Alex is envisioning are rather the stereotype Japanese anime trope. Sigh.... did this MC forget his living in a world where harem ran rampant since in time of memorial? Take King Solomon for example. He got like 700 wives and 300 concubines. Which sound insane but plausible considering how the world works in those ancient times. Alex is just being radical in his modern view? What a dull dream this guy have when he's OP at this point.
Author... there is a severe lack of Mitsuha... she is my favorite here... had her be involved in the moonlight world and interact more with mc and the other girls.... so far she is like a background character, she is supposed to be one of the heroines!!!! And mirtsuha is extremely smart and determined.
Author can he not just buy the divine authority of balor aka his mystic eyes that actualizes death with a glare or simply creates storms at his focal point of vision and become a modern divine spirit. Honestly he already has one authority so what if he gets a few more. He can just buy several authorities. considering he studied astromancy he can learn anima animusphere or buy astrea's authority over stars. Honestly he already has true magic now he needs a few authorities. Specially offensive ones. If I remember odin's eye was still available in the store. That's pretty much omniscience on steroids
