Sooo, a new character is coming very, VERY soon. Here's her bio.

 Takanashi Minami (Takamina) the 14th:

Rumors say that she may be cute and perfect on stage, but she is actually a spoiled brat. Unfortunately, these rumors are true. She has never revealed her true identity to anyone. After graduating highschool, she went off to Japan to be a member of AKB0048. She lost all contact with her friends and forgot about most of them when she had become a successor. She used to be a nice and sweet girl, but that all changed because of one dark event that happened in the past.
