Kyoutarou Ichikawa may look like a shy and reserved middle school student, but deep within his heart is a bloodthirsty killer. His ultimate desire is to see his classmate Anna Yamada's beautiful face writhing in pain before he ends her life. But this fantasy may never come to fruition, as Ichikawa starts to see an entirely different side to Yamada.

Often seeking refuge in the library, Ichikawa frequently runs into Yamada. It is during these encounters that Ichikawa realizes his model classmate is actually an airhead who can never read the room. As they spend more time together, the boy cannot help but feel not only a sense of endearment toward the very girl he wishes to murder but also a desire to protect her at all costs. Is it possible that this sudden change in Ichikawa's perspective could lead to something more?

This show, like the title did say was quite ~yabai~ in the first few episodes but trust me it does develop fairly well in the later episodes.

I thought this was just gonna be a chunni freak show with weird fanservice which it manages to fit in quite a good amount of, the boisterous and ultra well endowed little giant of girl yamada anna , (who we are somehow supposed to believe) is a middle school student and a model is alarmingly unaware of her antics of overeating and accidental fanservicing which are fueled by the chunni and Perverted delusions of our main lead ichikawa who ...

You know, I don’t really mind when a show divulges (or better yet evolves) from its premise, even if it was character based. Of course as the character grows, motivations change and the circumstance changes with it. Like in Love is War, the whole premise is trying to get the other to confess, but when they get together, that premise is gone, but still because of how the characters were developed, there was still a lot more story to tell. The premise evolved and changed. That is a good series. But I’m sorry, you cannot just forget your premise of, oh yeah, your main character ...
