Story: 7
According to some of my friends and online reviews, K project lacked plot. However, I found the story rather enjoyable. Shiro, a boy with amnesia, gets blamed for doing something he has no memory of doing and goes in search of the truth. I liked the idea of the swords and the clans, but some of it was very confusing. It's not bad for a short anime but others like No.6 explained things a lot better with short amount of episodes.
Art:9
Now here's something the anime did really well. The art was fantastic - one of the best I've seen. It had a different feel than other anime.... Kind of a "tropical" feeling, with all that blue. Backgrounds were really well done, not crap quality at all.
Sound:7
The opening and ending songs were great, not the best though. I don't have any problem with those. One thing I just have to mention are the soundtracks, especially those played during fight scenes. Can't they have something more... Intense? It doesn't really suit the mood of the anime.
Character:8
I didn't like how Shiro was actually someone else, but that aside, this anime had good characters. I started watching this anime because Shiro and Kuro look like Kanda and Allen from DGM, however Shiro and Kuro were unique in their own way. I love Shiro's personality, especially his cleverness.
Enjoyment:9
I enjoyed this anime. The art, the characters, and even the songs... They were well done.
Overall:8
Pretty average, definitely worth watching.
Well, I'm not so sure how to end this review... So uh the end? XD
