Mansplaining the manga...
This starts off with a bang. The hero is fed up with his role and wants to switch to the demon side filling up a work application and submitting his resume to the Maou... that he just beat up in battle, destroyed her castle, annihilated her army... you get where this is going.
Anyway he's there in stealth mode to prove his worth and join the other side which is where the story begins.
It's also where the story ends because the entire manga in nothing but him mansplaining the women's job to them. That's it. They're incompetent morons and he, and only, knows
how to do everyone's job right.
There are two other men in this manga and the way it deals with them is beyond pathetic. One is a dad and they take him out for the picture almost immediately so the MC can mansplain to his daughter. The other was already a bit iffy as they made him slim and on the feminine side in comparison to the MC but... yeah it's drag, they couldn't have the MC instruct a MAN on his job. They put him in drag and had him act all feminine so the MC could "very literally" look down on him and Mansplain while the other is in tears.
This started off with a good premise and the situations the characters are put in are interesting to start with. The manga however refuses to do anything with them. The MC, each and every time, stands over a woman looking down and tells her how to do her job "the right way".
If you've watched "I've Been Killing Slimes for 300 Years and Maxed Out My Level" this one has a very similar vibe only the art design is more generic and the characters flatter than a board.
Interesting idea, boring execution, boring art, crappy dialogue, VERY repetitive and predictable.
