- Both anime are Isekai's but in Devil is a part-timer, the demon lord ends up in the human world whereas in how not to summon a demon lord, a human in his demon lord form ends up in a game.
- Both the anime are filled with cliched anime tropes where the MC who is dense as hell forms a harem consisting of a furry, a tsundere, a well-endowed waifu girl etc
- In both the anime, the demon lord is the good guy (no one knows why) and does most of the work whereas the girls are just useless most of the time
"Isekai Maou to Shoukan Shoujo no Dorei Majutsu" is similar to this anime in some ways, instead of a deamon lord the main character is the devil of another world/dimension. The main character is also pretty strong and turns out to be a better person than to expect from the devil.
