She passed to Tsurugi Kyousuke and he passed to Nishiki Ryouma, who passed to Nishizono Shinsuke. Shinsuke passed to Shindou Takuto and Shindou passed to Amemiya Taiyou, who passed to Kirino Ranmaru. As Kirino passed the ball to Zanark Avalonic, Zanark passed the ball to Fei Rune and he made the final pass to Tenma again, creating a lightning mark. Due to the several passes which were made, the ball became very strong, and Tenma was able to score his team's second goal using God Wind.
Usage in-game
After the cutscene ends, the receiving player can start passing the ball to each of the 10 other players on the field, including the Goalkeeper. The more individual players are reached via passing, without losing the ball or getting an offside or throwing it out of bounds, the stronger the first shot performed by the player will be. It's still possible to pass the ball to players who had already received, although the ball will not accumulate any extra power (signaled by the lack of sound and visual effects). It's also still possible to shoot, albeit with much less power, without passing the ball to some or any of the other players.
