Natsu no Arashi (summer storm) is not like your average drama/slice of life series.
It started the series by some complicated things like time travel and no character introduction at all, somehow this will give 2 kind of impression for the viewer :
1. This is a "boring" anime.
2. This is interesting, must watch the other eps.
And if you choose the 2nd option (recommended by me), you will eventually enjoy the series.
There story revolves around some boy named "Yasaka Hajime" spending his summer time in his grandfather house. There he met with a sixteen years old girl name "Arashiyama Sayoko" who claimed to be
a ghost. From here on the adventure between hajime who knows nothing about the world (world war, etc) and arashi who try to help the people by traveling through time begin.
The art of Natsu no Arashi is a little different from another shaft work :), it present you with a bit old style drawing of character (but the cute eyes remained) and enjoyable environment, yeah it's summer afterall.
The seiyuu was very great, I always know that Shiraishi youko(hayate the combat butler seiyuu) was a great seiyuu. The way she say "hajime-chan" is great!
Great! The opening give you this "past" feeling :p you will know when you hear it.There are also some great insert song too.
The character cast was very good!
The main male protagonist give you a good male impression at making decision and also the ice breaker at some moment, the main female protagonist is a caring person and easy going. There are also another character that goes with complete different personalities with the main character. Cross-dressing character also exist in this anime. These character cast make this anime lively.
This is an definitely an exciting anime, as it cover some slice of life/drama about world war and peaceful time, and also some scientific comedy about time travel.
And you'll eventually realized that the character draw you to love them even more.
"No matter how many years pass, the warmth of summer never changes.
So, when this season comes around, I remember the summer of my thirteenth year my day as younger boy, when i know nothing at all
Even now, it remained unchanged within me."
