Let Dai
This really messed me up. I don't know how many times I cried while reading this. Such pure love showed in that innocent way. Not ever was it ''too much'' - just simply sweet. That bond they had felt so special. It's also amazing how every character got their special moment. The story didn't focus only on main ones and their love life. It was just... life around them in general. Additionally - this isn't some ''happy ending'' story. It doesn't have a tragic ending either. It's more realistic than any other manga I've read so far. You're guaranteed to feel all kinds of emotions. I'm never forgetting this one.

Honestly - it went on my "favorite" list. I also think that the artwork is amazing. Unique compared to other mangas. Is it disturbing and full of gore? Yes, but that's what makes it so different and somewhat exciting. If you're sensitive to these kinds of things - I do not recommend it for you. But if you're a fan of bloody scenes and horror... fascinated by psychopath's mind - it might be perfect for you. Like some other folks mentioned - don't get put off by the rating. Most of these are because of people not being able to handle such messed up manga. But it has a great storyline, well thought through.
