I don't know why I haven't thought of this before, but:
Would Koto consider Doctor Who Bishoujos one day?
You could make adorable Amy Pond, River Song, Clara Oswald, Missy/The Master, Martha Jones, Rose Tyler. The possibilities are endless and the fan base is MASSIVE! Not to mention they are pretty free with the licensing since they have GD sonic screwdriver pizza cutters for crying out loud.
Also, any chance of us getting an Ash Williams from The Evil Dead/Army of Darkness?
