final hadoukyu shot
This is a form of Hadoukyū that hasn't actually been officially named by Takeshi Konomi. Kawamura has only used Final Hadoukyū once, during his match with Ishida Gin. After losing 23 points in a row and getting down 5-0 40-0, he uses this shot with the inspiration of Akutsu. "Final Hadoukyū's" true power level is unknown, but it was said by Gin himself that it was greater than his 108th style Hadoukyū. When Kawamura used this shot, he injured Gin's wrist and forced him to forfeit. This form involves using the tennis racquet frame, similar to Wild Ball,and it was also thrown further away than normal serves, due to his unconsciousness.
