The internet.....Sorry, that was unnecessary. I guess try [Kissanime] If they don't have it, you can request it.
It might be hard to find actually. It's a movie so it goes to theatres first, You don't usually see it online until it goes to dvd
hmmm some japanese cinema. . . well anyway. . .hmmm kissani is good. . .animecrazy is also good also gogoa. is also good. . haaa i miss the old days of crunchyroll. . . .
You need to wait for it, japan were so good with their cyber it take up to half a year before you can watch the movie online or you can watch it at the nearest cinema
