The anime does have a few good ideas on paper, but it's like the skin of the body, but nothing on the inside. There isn't any bones, no muscles, and no organs. The show doesn't really dedicate itself in digging deep into any aspect. The characters are barely serviceable and what you know about these people from their introduction is largely the same by episode 12.
Yuuki, the main character, lives in a world where women have power by eating "peaches" from another realm, but men can't access this power. The reason why men also can't be empowered is never explained.
Yuuki really does make Deku from Boko no Hero seem like deep character. Yuuki likes cleaning and wants to be a hero....and that's the "be all and end all" sum of his character. He eventually gets transported to Mato and is rescued from monsters by the female MC, Kyouka. They find themselves in a bad pinch and she tells him that the only way that they can be saved is if he becomes her slave(relating to her power). Somehow and without an explanation, Yuuki understands that to accept this offer he has to lick her finger.
No, you did not mis-read that. He licks her finger.
When the contract is complete, he becomes a huge white monster. It is never explained why he changes form. It also never explains why other creatures that are slaves of Kyouka don't change into another form.
Yuuki is later introduced to Kyouka's military division members. These are girls who barely have any background info and the show doesn't really explore these characters. So, we have a male with a complete surrounding cast of females......can you guess what happens? If you guessed that there is a harem trope then you would be correct. What makes it bad though is that the girls in this show want Yuuki for little to no reason. What a cliche.
Now, all of this is bad and I can mention other bad things about the show, but I will skip to the end and just tell you how this anime insults your intelligence and disdains you, the viewer. Whenever, Yuuki transforms to a creature by Kyouka's power he eventually has to be "rewarded". This is the requirement for Kyouka to use her power. It is never explained why she's the sole person that has such a stipulation to use her power. In any event, Yuuki's "reward" is always something perverted....and it feels like the show is trying to cover up it's shortcomings and laziness by adding these perverted things.
Of course there are perverted anime out there, but this show tries to represent itself as something serious.....but will try to distract you by such an easy way "out" to avoid from taking time to think about it's faults. That's insulting.
