It's just as bad as the anime it comes with. This time I was actually ok with it because my hatred for people who praised the series has finally passed. I read the manga, and my opinion had not really changed.

Story: It had many plot holes, and was a general crash fire. So this yandere girl, Satou finds/kidnaps a young girl, Shio. If you dive deeper into the story, you find out that Satou is completely deranged, killing people and harming them just to have her "lover" to herself. Shio is under 10 I presume, so so far it seemed like yuri trash. To explain Satous actions, the story proclaims she was abused and mistreated by her guardian, but it never justifies why she is passed off by judge, who ever she gives the death sentence to, they probably deserved it. Even though she is a mindbroken teenager who doesn't know what she's doing, and is most likely in a weak mental state. Shio can't really have much character, as she just serves as another clarification for murder. She has no character, besides how pure and sweet she is. The story convinces you to fall in love with the character Satou, even though she's a murderer who is completely out of her mind. It's because of this that the story does not understand that placing a young individual child in the care of a psychopath usually doesn't end up well. As you can see clearly, the story acts like the child is completely well and nurtured because Satou cares about her. Satou has to face many other characters and defeat them just to remain with Shio. It doesn't particularly strike me any emotion, rather than disappointment and boredom. The story doesn't really tie together many of their plot points and it just ends up having one character going on a murder spree and never really seems to take advantage of the idea that a high schooler is allowed to kidnap children and murder other characters even though they basically had nothing wrong with them besides one or two creepy factors. The story is pure shock value there's no way and you don't get what's going on most of the time. The police don't play much of a part, and there are many cliche moments of justice, even though that's not the case. It's ok to have an insane character in your story, you can put them in a situation of any kind, and the basic lines of using love as an excuse can be a very chilling story, but you have to have realistic characters that also have a sense of quirk to them, or else they'll be so comically stupid that you realize the story was just for the wow parts. It shows buildup that has a weak foundation because of the way the story is loosely jangled together, when it shows powerful scenes, it often overestimates its own intelligence and punctures holes in its wobbly base. The whole mess afterwards is sugar coated and presented on an edgy storyline.
Characters: Let's start off with our main protagonist. Satou is a young teenager who is presented as an attractive and easygoing girl who sleeps with many boys which is later explained by the fact that she may have been sexually abused by her aunt. She then acquires a young little girl and is convinced that they belong together. Although this may be fiction. If you don't like like title girls being groomed, which I think everyone can agree on unless they are out of their minds, then this relationship has its flaws, Satou being in complete control over their romantic situation. Daichi, is a character who's only purpose is to get in Satous way, he is a pedophile masochist who wants to do dirty and dangerous things with Satou. He loves and maybe has a weird fetish(masochism) towards almost being caught by the police, etc. This is mainly for Satou to show her independence and badass side, although Satou is super two-faced. He doesn't pose to much of a threat, and is just a weak character for us to hate. Mitsuboshi is a young boy who works at the same job as Satou. In the beginning he is just a sweet attractive person like Satou herself, but Satou already loving another person(a small child, mind you) rejects his confession. He is left heartbroken and goes to his boss, but gets raped/sexually abused by her, he ends up being insane afterwards. His character showed promise but then was turned into an edgy, crazy boy who's main purpose was to target Shio, because of her "pure and heavenly" side. He is much like Daichi, from an analytical standpoint. Next, we have Shoko and Asahi. They are good and well meaning characters, even though Asahi may seem a little mind broken because the abuse he suffered, but more on that later. The only reason that these characters didn't really have an affect on my opinion is because they didn't play too much of a meaningful part. Shoko was a nice and simple character, she was the voice of reason and a girl who really cared for Satou. Asahi was Shio's older brother. He wanted to find her after he escaped his abusive fathers grasp. He was separated from her when he decided that Shio and her mother should run away while he dealt with his father. He was broken a bit, and convinced that his mother was a nice person, even though she abandoned Shio. Asahi and Shoko would make a great couple, and me saying that is pretty surprising in this type of trash manga. Too bad I know Shoko gets killed.
Art: It was effective and simple, there wasn't much to note on it. It makes use of its decency to show characters state of being, but it didn't do anything clever.
Enjoyment: I don't mean to be rude, like what you like, but my standards can't deny that this manga was so painfully dreadful, instead of being invested, and was laughing my ass off at how stupid it was. Everything came out in the wrong emotion, disappointment, anger, laughing, and face palming. If you're like me who watches simple shows, comedy, slice of life, some horror, and romance, then you already knew this wasn't your show, but you could still dissect every scene into its basic form, and find out that it tries to make it's already weak points, into a masterpiece. It's like they didn't think of anything before they just sat down and started drawing on a piece paper after watching Mirai Nikki.
Overall: ...It's trash. Go look for another anime, don't waste your time on this one! It's a crash fire. If I could describe this in only one word it would be, A Painful Boring Disaster Waiting to Fall Apart. Did I say one word? Well it's disappointment brought me much more to the table. Go watch Higurashi, both seasons. It has shock value with some meaning to it. Wonderful story. Basically, WATCH HIGURASHI INSTEAD, IT'LL SAVE YOU A FEW DAYS. I read it so you don't have to.
