when is Mai-Hime 0 coming out?

Question

I saw the trailer but they didnt tell the date

Answer 1

The only know publications of Mai-Hime:
1. The manga having 5 volumes. Alternate story telling of the series (which is always a plus)
2. 24 episodes
3. 24 omakes or extras released with the dvds. The first one is the fake trailer for the Mai-Hime: The battle of Fuuka movie. Release date: 20007.
For Mai-Otome:
1. The manga which has 5 volumes and same as the Mai-Hime manga. Also came out with Mai-Otome Zwei and I just found out there is a Mai-Otome Arashi.
2. 24 episodes
3. 12 omakes for the series.
4. An OVA encompassing 4 episodes.

There is a novel called Mai-Hime Destiny which is supposedly to be the real sequel to Mai-Hime series.
