Kyou no 5 no 2 (TV): Takarabako

A collection of like five minute shorts strung together to make a 23 minute show. Normally not the best way to do things, but this was really cute, and each short had a theme. Then the themes became the show. The music was really good, and the lyrics to the out music of each episode changed, and was a bit melancholy, while the melody was haunting. All in all a pleasant, if short, episode. This is, in a way, a stand alone kind of OVA, and is understandable even if it is the first dive into this collection of Kn5n2.
