To begin I love love LOVE this anime so far!
I was hooked after the first episode; thought the whole mood really changes after the first episode. Ledo is such a great character and his changes and progression throughout the series is really fun to watch. The series starts off on a really serious tone but eventually get light and more comical in some episodes.
I would recommend this anime to anyone even if you dont like this genre much (personally I really dont like mecha type animes)
Definitely give this one a chance; you wont regret it!
