No you haven't, because that's insane. It's not insane if it's in an anime though.
Story: 8/10
The story is very interesting, mainly because it has some mystery to it. Scavenger hunt-type anime are very interesting and that's why I like this anime. Sometimes, there would be scenes where there would be just people talking for about half an episode, which dragged the anime out even though it was 11 episodes. It wasn't that funny to me, but that doesn't matter mainly because the mystery in the anime overpowers the comedy. There's also romance in the anime but it was very slight. Though there is action, it's quite boring but adds to the mystery side of how each of the 'Nanana's Collection' works.
Art: 10/10
The art is magnificent and I have never seen any illustrator draw eyes that colorful. The animation is really smooth, for example the gears in the ruins or the chest animation. I would even say that this anime has one of the best art in all of the anime I have watched.
Sound: 8/10
The OST fit each scene nicely and the sounds of the gears or magic weapons being used is quite nice. To me, even though the OP and ED was nice and catchy, it didn't quite fit the theme of this anime. The OP and ED had more of a slice-of-life vibe to it, rather than a supernatural/mystery vibe, though it doesn't affect the anime that much.
Character: 9/10
When I first heard Yama Juugo's voice, I instantly recognized it as the voice actor of Kuroko no Basket's Kagami Taiga. I saw the list of characters and their voice actors and boom, I was right.
Yama Juugo, the protagonist of the story. I would think that he is a very overpowered character with that 'cool' vibe, but he's somewhat weak and is a pervert, but he can control himself most of the times. He's very kind and always thinks of others before himself.
Ryuugajou Nanana, a ghost NEET who has been living on pudding for a decade (or maybe even more). She's a very famous figure in Nanae Island, as one of the Great 7s who planned the island, though Nanana is bound to room 202 and is forever stuck in there, until she can move on. She's a very cheerful girl and would help Juugo whenever he is depressed.
Ikkyuu Tensai, the master detective and probably one of the smartest people in all of the anime I have watched. Once she finds clues, she will figure the problem out instantly. She cares for Juugo and is good friends with Nanana.
Enjoyment: 9/10
I really would like to see more anime that have a story like this. I really like mystery, because that would make me watch the anime more and wouldn't bore me.
Overall: 8/10
Even though this anime ended on a cliffhanger and it was 11 episodes short, I still give it an 8 mainly because it was an original story and it intrigued me.
The anime can be violent, so this isn't for the light-hearted. Would I re-watch this? It's only 11 episodes, I probably would be bored re-watching it as it's a short anime.
