I'm going to be straightforward here. Saying that Koe No Katachi is one of the best mangas I have ever read would be a cop out because Koe no Katachi is THE best manga I have ever read. I find it hard to say because it's a shounen that has no swords, no titans, no Death Note; but it has me on my seat regardless.

The story is well told. The mangaka doesn't spam you with useless knowledge nor does he/she have excess dialogue that a lot of shounen manga have problems with. I don't want to say anything about the events that take place because just telling you what this manga is about would ruin 5-6 chapters. I say 5-6 chapters because, if I recall correctly, that's how long the prologue of the story is.

Characters are far from cliche. Characters feel like they're human and their behaviors are not forced. It also creates an uncertainty of how you think they will act. This entire manga is about character development so they're designed to like most of them.

In summary, I really love this manga. It is a true masterpiece. Every chapter has me on the edge of my seat, wishing I had a time machine just so I could read the next chapter. I hope you liked my review and enjoy the manga even more than I do.
