Love it because each character is so adorable; hate it because of its limited release^^;
Konata and her friends were cast to cosplay their respective Macross Frontier character probably based on their hair length and color. But it's great to see that Miyuki gets to cosplay Sheryl Nome. Both of them are voiced by the same seiyuu.
Hobby Net has this entire set up for pre-order (not applicable for international buyers I think).
All 7 types:
Type A: Konata Izumi (Alto Cosplay) Premium Figure (all 1 type x 4)
Type B: Kagami Hiiragi (Klan Cosplay) Premium Figure (all 1 type x 4)
