Yeah so for this show I feel this was a decently low-quality show but tbh I'm saying it's a 7 because it was decent and the ecchi was pretty good too. Ok fine maybe the ecchi is what is bringing it to a 7 for me ok.
Story; well it started off well enough I liked it in the beginning and thought it was pretty cool, but then around the last 3 or 4 episodes it felt like wtf? the last episodes just came out of nowhere and didn't really make a whole lot of sense to the rest of the show. It also made me dislike the MC which sucks because I kinda liked him at first and I think if the show took its time getting to those last few episodes id like it a lot better.
Art; Yeah it looked pretty decent. I think a lot of the designs for stuff were pretty good not the best ever but above average.
Sound: Ok the OP doesn't need to go nearly as hard as it does especially for a show like this like the op is actually really good and this show kinda sucks in terms of quality, idk it's weird but I guess it's a good thing.
Characters; eh most of them are just alright. I like the main girl that's always naked the best, the blue-haired girl is cool too. The MC was fine in the beginning but I kinda started to hate him by the end it just seemed weird and out of character a lot of the stuff he was doing. Also didn't like how OP the MC was like I get he was supposed to be but like it was just too much I wasn't really a fan I wish he'd have to earn the power more. But yeah overall the characters were just kinda meh I did like the one girl tho I thought she was fun and interesting.
In terms of quality, id say this show is like a 6. Like it has some cool things going for it but tbh that's about it all the other stuff is just pretty average and I feel those not as good aspects really just keep the show at about a 6.
In terms of me liking this show yeah it's like a 7. I mean it might be low quality but it's still fun for me to watch and like I said the ecchi is pretty decent IMO and that automatically is always a good thing to me. So yeah the show might not be great but I still liked it a lot.
