-Short Answer-

Well... As a One-Shot Manga "Shikkoku Shoujo to Shiro no Doukei" is quite a wecloming read as it doesn't overstay its welcome, and gets its message across very quickly. I will say I am left with wanting more from this after I completed it, but I highly doubt anything will ever come up again about this manga. If I had to summarize what my thoughts on this manga are in a sing'e sentence it would be "Everyone should give this One Shot one chance".

-A Little Bit More In Depth Look-

Well... I will say the story has been seen alot, but it has a much better take on the subject matter than any works that would be considered similar to it, and the characters also fit that description as well. The outcome of the manga though easy to predict leaves the reader coming away from this manga feeling in my opinion refreshed and ready to delve back into other works. Now as I type this I see this is almost as short as the top paragraph so you will have to forgive me mainly because I am lazy.

Anyways that concludes my review of "Shikkoku Shoujo to Shiro no Doukei".
