Afterwards, this hissatsu tactic was seen yet again in episode 32, but only in a flashback where Tenma, Shinsuke, Shindou, Aoi, Akane and Midori were thinking of the past matches, and it was not used in the episode itself.
The power of this hissatsu tactics in the Chrono Stone game is 40.
Four team members pass the ball to each other; each time they do, the energy gets transferred with each member's pass into the ball until it gets fully charged and gets a glowing appearance. They then pass the ball to the last striker who has a high enough shooting power to volley the ball on the opposing side, causing the energy to explode directly at the centre of the opposing team's defence, which makes an opening for the upcoming striker to try to score a goal.
