Details of 18th single was actually release some time ago...
But here is a full one,those who are playing Ameba Pigg...
Your chance is here to vote for your favourite units that are in the 18th single plan...in Ameba Pigg.
All you need to do is to get the flower of the different unit and plant it around the 3 different maps of AKB48,i think the more number of flower an unit have will win.
Now i just wonder why Sayaka is alone in a group...but she is going to sing Enka,which is seriously interesting.
