This OVA continues with the story line of the main anime it adapts the volume 8 of the manga even though it is bundled with the volume 10. Anyway the quality is the same as the main anime and it adapts the manga storyline good enough. Anyone interested in continuing the story start from volume 9 (chapter 36) it gets pretty interesting when Staz's dad enters the scene (probably one of my favorite character in the manga) Just reaching the word minimum. a a a a a a a a a aa aa a a a aa aa aa a a a aa a
