Honestly, I don't understand why this anime is getting so much hate. It's not bad but not a masterpiece. It's something to watch when you have nothing else to watch.
The story itself is pretty bland but not in a bad way. More or less you can pretty much predict what's going to happen but again its not bad. If it had a little more oomph in it it would be pretty good.
The Art style is pretty basic too. But it's not horrible. Like I always say it could be worse. also boobs ( ͡° ͜ʖ ͡°)
The characters in my opinion are really likeable characters, main chick is kind of bland and annoying but still likeable in a way
(boobs ( ͡° ͜ʖ ͡°) ). Main character is a funny perv (like issei from Highschool DxD) and he is hella op (if you like OP MC's this is a anime for you). Finally, all the side characters are very likeable, no issues with them.
Again, this isn't a masterpiece anime, if you have high expectations, don't bother watching it. If you're someone who has nothing to watch and you wanna watch something that has, boobs ( ͡° ͜ʖ ͡°) , strong MC, somewhat decent story then I feel like you will watch it. Gonna read the manga.
