@ Oikaze: Maybe it's the magic of the Gokkies ;). But I've changed my avatar now, it matches better with my username.
I remember the extra scenes of the Mechaike Okajo special very well. The scenes where they had lunch with their "parents". Konkon was the first who met her "parents". She got delicious lunch and looked exactly like Erina here.
Erina is currently on rank 2 in my personal Kyukki ranking (behind Zukki :). I didn't like her so much at the beginning.
