Simple work, where the protagonist gets a ring that gives him the right to send several demon girls, the development goes well, basically he will meet more girls and conquering them, which is pretty cool at first but then is repetitive, in this part As far as we can tell, this style of work is always like that, but what I can't stand is the fact that a rival appears who almost kills the protagonist and yet at the end of all the confusion the protagonist forgives and saves him. Simply horrible, author spoils the story with this! I DO NOT RECOMMEND
