I got more info on Nanaca crash. It turns out it's based on an ADULT anime called Cross Channel and they even have an import game of it out on PC & PS2!

And I found a great site in english (hells yeah!) that explains the instructions in good detail

plus I also discovered special Cosmic Force Field moves:
1. Hit the "purple" girl to initiate "block" status, then land on the "green" girl when the block status box flashes "VS. C.F.F(C.osmic F.orce F.ield)" to trigger Type-A double impact. this will propel you twice as hard when you land on a boost character. your guy will turn green.

2. Hit the "purple" girl to initiate "block" status, then land on the "red" girl when the block status box flashes "VS. C.F.F(C.osmic F.orce F.ield)" to trigger Type-B charge blast. This will in turn break you from the grasp of the "green" girl for one time instead of stopping you immediately (the elusive *teleport* I was speaking of earlier). your guy will turn red.

3. Hit the "purple" girl to initiate "block" status, then land on the "blue" girl when the block status box flashes "VS. C.F.F(C.osmic F.orce F.ield)" to trigger Type-C parachute death sentance. This will boost you directly above everyones head for approx. 1000 meters or more! your guy will turn yellow.

4. Hit the "purple" girl to initiate "block" status, then land on the "yellow" girl when the block status box flashes "VS. C.F.F(C.osmic F.orce F.ield)" to trigger Type-D bound boost. you get a boost everytime you hit the ground. your guy will turn grey.
