Just recently watched the movie, and wanted to help out :D
So far I've tried my best to improve the look of the Wiki, by adding a better suiting background and colors that fit the series. I also edited the templates to fit the theme, and created new ones as well.
I added those templates to character pages to replace the old and broken ones.
I also made a page for the movie since it didn't already exist.
And lastly, I made pages for all of the soundtracks and songs in the movie, and added lyrics to the song pages as well.
There isn't much else I can do on this Wiki until the movie releases in HD, but I don't know when that will be.
When the film does eventually release in HD, rest assured I will be making gallery pages for the film and characters.
Until then, I may not be much use here, as the only other thing to do is add information to character pages, but sadly, I'm not the best at typing/writing out information.
However, I may make pages for the manga series if I can find enough information about it, as well as pages for the light novel.
