DC Comics will be introducing a new lineup come October, starting with “Gotham Academy”, and continuing with other Batman shadows  Arkham Manor and Gotham By Midnight.

Comic Book Resources says:

Drawn by Cloonan, the promo images feature Olive Silverlock, whom she says “is attending Gotham Academy on a prestigious Wayne Scholarship”; Kyle Mizoguchi, “dreamy star of the Gotham Academy tennis team”; and Mia “Maps” Mizoguchi, an “aspiring cartographer” who “has trouble controlling the volume of her voice.”
