Spoiler free review. This is the most amazing anime i've ever seen, the storyline is just AWESOME! I liked it so much because i love anime/manga that have time travel, they are very interesting and fun to watch. Though they do tend to get a bit confusing... Anyway, i recommend this anime for all ages, because it's great and not for a certain age. I don't know much Japanese, but i watched the raw version and understood a bit. Sadly there isn't any English subs :( I think there is in Spanish, Arabic and a bunch of others. Dunno why there isn't one for English.. The Manga is kind of differentthan the anime, just a warning.

Last but not least, even though this is an old anime, it will always be my favorite. It's so cute!
Thank you for reading this!
