The Crystal Tower (formerly known as Project Takagi) is a holiday special featuring Magical Girl Gina. It follows At The Break Of Dawn in the Outliers and Outsiders series, but is more a spinoff or special than a sequel.
When a fancy Christmas party goes horribly wrong and terrorists take over the Liberty Macvonden Building, it’s up to Magical Girl Gina to save the day and her girlfriend!
This was meant to be a small project, but quickly exploded in scope. The current version is rough, but the plan is to come back each year and add a little more.
