Invincible Rainbow Arrow (JP) AI: The Somnium Files (Grand Finale Ver.)

AI: The Somnium Files is an amazing game, and what better way to end it all off but with a musical number? I saw that no one had uploaded the video along with the JP track, which I love just as much as the English, seeing as I went through the game in Japanese. And obviously, I own none of the audio/visual elements featured in this video.
