What do te think should happen with the series?

If the Anime were to some-what continue how would like for it to continue?

1. A Season two with completely different Anime only villains

2. Restarted from the beginning and for it to be like the manga (like Full Metal Alchemist & Full Metal Alchemist Brotherhood)

3. Make multiple OVA's with the Manga's storyline (Like Hellsing & Hellsing Ultimate)

Me personally would prefer it to either Restart o for OVA's to be made
