Just saw Miyako on the N-Gacha (but didn't get her T_T).

Yesterday I saw a guy asking at Nutaku's Facebook page if Makiko Shinnou and Satona Okada were paid-only cards, and the answer was "No premium currency required - they're all available from chance rolls in the Elite Guard event section."

So, from that answer we could say that the other two cards aren't suppoed to be at the normal gacha, but at the event chance roll.
Just a random thought, but it may make sense.

Happened to me yesterday. A Pero friend made me notice that a lvl 100 guard I spotted had an inusual high ammount of HP.

Another weird thing.. ..Ultra Guards are supposed to appear during the second half of the event, but I'm sure I got some better rewards after supporting others, and the message said something about Ultras.
I can't tell if that points to another kind of Guards, or if that was a mistaken word on the message, or maybe I'm just mistaken. But if it's true, maybe that could explain why some people are facing guards with higher HP than they should.
