The Time to Start the Match

is episode 35 of the Beelzebub anime.

Summary
The volleyball game begins, with both teams proving to be competent at the sport. The Ishiyama High gang commit fouls and play dirty, gaining them enough points to make the first set a close one. Izuma starts serving using a fighting technique to power the balls towards Kunieda with such power that she's unable to dig them out. Kunieda's arms are burned badly from trying to deflect the balls, and she substitutes for Furuichi, who proves to be totally useless. A determined Kunieda returns to the court and manages to start digging out Izuma's serves. The Ishiyama High students start playing earnestly, trying their hardest at last. Both teams are at match point when Izuma hits a ball that heads right to the edge of the court, beyond Kunieda's reach. Oga jumps ahead and manages to return the ball, with enough speed and power that the 6 Holy Knights are unable to return it, causing Ishiyama High to win the match.
