In 2014, Rokudenashiko was arrested twice after she used crowd funding to create a Manko-kayak(giant vagina boat) by converting her own Manko (female genitalia) into 3d data. After eight years, she was able to transform her 3d vagina data into a patrol car using 3d computer graphics. The driver of the car is Manko-chan, a character of vagina, made by Rokudenshiko. The background is the Koiwa Police Station.
