This is a Shockwave Flash game where the object is to make Nanaca crash into a boy named Taichi with your bicycle and set a new distance record for how far he flies and bounces. Strangely morbid fun. The game is in Japanese but is entirely mouse-controlled.

To play, click "Start". Click and hold the mouse button to set the angle then release the mouse button to set the power and launch Taichi. Taichi may collide with various characters along the way, each of which affect Taichi's trajectory. Some of the girls flash "SPECIAL" above when hit: click the mouse button within 0.7 seconds to trigger the girl's special power which can boost Taichi to even greater heights.
