Yeah i think there are only two natural Magic Types? Kuko and Detective-Chan.
Kuko is really helpfull on some EX Aqua Shadow Maps. Especially the one with the Saboten Twins.

Yep the activitiy is rather low the last few days to be honest (The Forum lurkers are an exception though. Sometimes more people viewing that Forum instead of the Nutaku one).
I hope the Devs release the Mobile Version on the 30th of this month so we can claim our Rewards. That should help make the forum more lively
