Well as one would have it, Over Drive 26 has finally appeared on the net in raw form. Curious to know if this was really the last episode, I downloaded it, and can confirm. This ends the little arc that Episode 1 has begun. Whether or not this is it for Over Drive or not, we're not sure. Season 2 may be a high possibility. Unlike other animes, Over Drive seems to stay decently on track with the manga, and still has a lot more to go on.
If we hear any word of a Season 2, we'll be sure to keep everyone updated.
