Koukou Tekken-den Tough v12p102
Power-chan #1 is an apparatus created by Seiko Miyazawa to increase impact power. It is a series of springs attached to Kiichi's limbs and body and connected to the wall. This provides resistance for punches and kicks. But that's just the first part. There is a long heavybag about twenty feet away that he has to get to before he can actually throw any of those strikes.
