For me, it was one of the best anime that i ever seen. There is action, romance, sci-fi. The art is not common and the colour are used very well. The story may seem normal or like another anime but it is not. Using famous character from the past and discovering about them is very interessing. The main character is a nerd about military plane but it made us love her because she is not a weak person. She may seem but is not. In fact, she does not look a like those typical character and that is why the anime is so interesting !! Please watched it! And I hope my review helped you !
