Charlie!!!... xD
I've already watched the other 2 before this one and I love the series. This one in particular is a bit more random than ever (if that could be possible), the formula will get a bit old in the future if there are more (I hope there will be more).
The animation was a lot much better and it even looked gorgeous in certain parts, like underwater. The song, as always, was simply great and the reference to the ending of the first one was great!
Keep it up! :D...
