For those of you that enjoy WWII, alternate history, and maybe some military action, this is a decent anime. The biggest drawback is the fact it was never finished, they just dropped it on a cliff hanger, forcing you to read the manga. It's an anime about individuals from the Japanese navy that, for unknown reasons, randomly went back in time during the WWII era. Upon trying to be neutral to avoid changing history, the inevitable happens that escalates to them getting in battle. They rescue a man who was very cooperative and kind, but it was decided to allow him to read history booksthat essentially predict the future. Upon doing so, he was inspired to create a new future, a new Japan, which the rest of the crew had mixed feelings about. The rest of the show's drama revolves around that and it's incredibly interesting for it.

It's a shame too, because it was really good, but it ends on a nasty cliff hanger that will never be satisfied without research.
