Latest news: there are 3 achievements (as said in the staff anouncement) and the 'converted' counter helps us to see how close we are to the last one.
Achievements:
Magical girl - being a magical girl at least once
Hero - for making 25 converts
Hotblooded hero - For being a Sentai at least once
There was a bug where the Hotblooded Hero wouldn't grant properly (and may have been mutually exclusive with with Magical girl. But it's fixed now.

If you don't have an achievement yet it might simply be server lag.
Anyone else have any useful information? Please PM me (cause the quoting is getting wild)
