Shinobu Kamizono's model from Gal*Gun: Double Peace can be found within the game files, likely having been ported over for testing purposes. Comparing it to her model in Gal*Gun 2 reveals various subtle changes made to the character models in the game:

• Due to shoes now being treated as a separate piece of clothing, the "Body" models are now barefoot by default.
• Skirts and ties were made looser in order to show off the cloth physics.
• "Face" models are simplified, being flatter and smoother with rounder ears.
• The overall polycount of the models are generally lower than before.
