Mogami-kun said: For some reason I thought this was already confirmed, must have mistook it for KinMoza or something. Not as huge of a fan of the show as others, but more Sharo and Rize are always nice.
There were 2 announcements that turned out to be fake then this official one.
LN_Author said: With light novels there are two factions:
younger girls versus older girls, or little sisters
versus big sisters. Childhood friends aren't
really that popular when they're around the
same age as the protagonist. So we're faced
with the prospect of choosing between one
of the main factions.
