This is one of my favorite animes! Reasons:
Story~ This story is a really touching story. I liked how we begin to learn about the characters' pasts during the story, how their pasts begin to unravel...First it starts off like any kind of slice of life story about two high high school students who are cousins. They wake up, eat breakfast, go to school, go to club activities,go home, eat, sleep..etc.. However after Yuuichi meets a few girls, it all changes...
Art and Sound~ I like the animation company a lot...I think that the characters' looks really match their personnalities. Also when the characters are suppose to look alike, they look alike. For example, Nayuki and her mother, they look alike a lot. Sayuri and her brother look alike. However, Nayuki and Yuuichi look nothing alike and they're suppose to be cousins...For the sound, there's not much to say, except that I think that the voice actors' voices match the charactes voices.
I hope I'm not giving out any spoilers so far...
Characters~ I think that the animation really match the characters. It's cool how all the main characters' personnalities are so different and so it makes them all unique. The number of girls is a lot higher than the number of boys. That's it.
The main characters:
Ayu: the more childish one (she's actually 17 years old)
Mai: the anti-social girl who is isolated by her classmates
Nayuki: the kind one
Shiori: the polite one
Makoto: the one who likes to pull pranks
Yuuichi: the boy who is surrounded by all these girls
This is only what I think of the characters... Oh, and sorry this review probably sucks, but I really don't know what to say here except that YOU SHOULD TRY THIS ANIME!! That's all. This is also my first review, so...I appologize that it's seriously lacking in some parts xP
