I have watched through The Devil Is a Part-Timer! and I Couldn’t Become a Hero, So I Reluctantly Decided to Get a Job. Now I tell you something about those.
In I Couldn’t Become a Hero, So I Reluctantly Decided to Get a Job. starts with introduction of main character, hero-in-training doing... training. Then he and other heroes-in-training are told that demon lord has been deposed and heroes and heroes-in-training alike are demobilized & disbanded. To earn his everyday bread, our hero, Raul, starts working in magical item store. Well... merchandise has strong resemblance to electronic devices we know, but those are powered by magic instead electricity. Same difference. He dislikes it and is hoping to prove his worth as hero. Until new employee starts in the place: demon lord's daughter. Cute girl by the way. She has some troubles, speaks evil things, but is eager to learn to speak and behave as she should. And she is enjoying it. From her Raul learns values of life, the universe, and everything. But other heroes want her to become next demon lord so heroes would get mobilized again and get to do what they were trained to do...
The Devil Is a Part-Timer! starts with info dump and fast paced action where main character, Satan the devil, gets his army slaughtered by humans. He manages to escape with his most trusted general through temporary portal ( = stargate) to another world. Guess where did they go? To Tokyo. He and his general find themselves have transformed to humans, nobody is afraid of them, casting magic takes great effort, and they have very limited reserve of magic. Satan learns quickly, manages to get money, bank account, ID cards, apartment, and part-time job in fast food restaurant. Little later he meets his archnemesis, hero, who had followed him through the portal. She is in much the same situation. After some minor conflict they settle in with uneasy truce. Hilarity ensues when everybody around them seems to think they're (former) couple. Little later show takes turn towards harem, and occasionally other people from their homeworld come stir up their peace.
I enjoyed watching both of those. Well worth the time spent
You know what they say, don't you? About how us MechWarriors are the modern knights, how warfare has become civilized now that we have to abide by conventions and rules of war. Don't believe it. MekWars
