I picked up this anime since it was so highly rated, and it looked like a harem and I kinda like harems so yeah.
Unfortunately, after watching all the 15 episodes, I can say that this is one of those anime that is not for everyone. It's hit or miss. For me, it was a huge miss.
It's unique. Not like any anime I've seen before. The format is that the anime frequently flashes words and phrases in the screen. I don't know if it appeals to people but I didn't like it. It's kinda annoying and I can't believe I endured it to the end and didn't drop the anime. And the way it focuses toooo much on the conversations. Ugh.
The fanservice. My god. There's good fanservice and bad fanservice. For me the fanservice in this anime is bad. A fking panty shot as the first scene in the anime almost made me want to drop it already. It didn't get any better.
The characters. I hated the main female character. She's a, how do I say this, dan-yan-dere claiming to be a tsundere. Without the dere part. I can't believe that I'd find a character more annoying than those wimpy loser male MC protagonists. The other characters aren't much better. One is a pedophilia grope machine who's only memorable trait is stuttering the MC's sentence, the other is a generic "I have feelings for onii-chan" girl with a unsightly character design, another is a generic big-boobed cat-eared fanservice girl. Only that lesbian girl was decent for me (I still don't like her though, just that I don't hate her unlike the other girls).
And the male MC is a raging perverted man who seems to be lusting for just about everything and everyone. Including the younger characters. I haven't seen an anime with worse pedophilia than this anime (there probably are, but this anime is popular.) Come on, stop groping and harassing that elementary school girl already!
The story and plot. If you thought that if you ignore the powerpoint presentations and shitty characters and pedophilia the anime will at least be decent, you're wrong. The monsters and myth aspects might be slightly interesting, but they were executed poorly. I didn't have any times where I wasn't bored when watching this anime, but there sure are a lot of times where was disgusted. No where in the genres did I find pedophilia and gore.
The sound is the only redeeming aspect for me. I loved all of the opening songs. I liked listening to Staple Stable, Sugar Sweet Nightmare, Kaerimichi, and my now all time favorite opening music is Renai Circulation. Kana Hanazawa really did good with that one.
Unfortunately, outside of the great music, it just doesn't click for me. It's unique but that doesn't mean it's good. I suppose some find the "flash words in the screen all the time" great, some like long conversations, some liked the grills and their personalities (I didn't), some have different tastes in fanservice, and some like openly perverted and pedophilic main characters . But not me.
Man I'm glad I wasn't interested enough to watch the next seasons. It now includes more child-y characters. It now includes incest, with the male MC's two little sisters. Yay for pedophilic incest.
