Platonic Harem Isekai

Harems have become too powerful. Heroes fall prey to temptation and poor relationship development, and no woman is truly safe from a life of emptily yearning for one man. When the Goddess of Reincarnation is taken out of the picture, her sister Vice-Goddess summons a new champion, a man who she hopes will resist the blight of haremhood, emaciate the men of Gaia from their self-deprecating stupor, and overall just be a decent guy for once in this world.

Watch as he walks into a female companion in the middle of changing, then promptly turns around, apologizes, and leaves without being magicked in the ass because it's not really that big of a deal.

There's only one bed? No problem.
Need some personal space? Gotchya.
Developing mutual feelings? Let's talk it out.

In this tale, the true fantasy is the fulfilling friendships and mutually-assured relationships along the way.
