Nostalgia is a video project that I did my senior year of high school. It involves Rika and Ryu in a somewhat out of character search for him in the present.
The following videos are both DRAFTS of a "what if Kurokenshin was an animation" idea- compiled in Windows Movie Maker.
The first is a preview of the opening, and the song used is Just Melody by UVERworld.
The second video goes into episode 1, which is the first few pages of Volume 1. Of course there are minor changes from the book-to-video adaptation :)
