This video from Super Dimension Game Neptune is all about transformations. Watch the heroines of Neptune change from everyday girls into console goddesses.
Did you see the sprites for IF-chan and Compa-chan? Graphics from Idea Factory and Compile Heart games like Octomania are used for their transformations in Neptune. Since Compile Heart and Idea Factory are under the same umbrella that wasn’t too hard to pull off. Nippon-chan, the mascot for NIS, has a fan service-y newscast reminiscent of Pleinair’s TV show in Disgaea.
The console goddess also… ahem… grow a bit after they transform.
Look at Neptune / Purple Heart’s measurements again…
