Double Grenade (ダブルグレネード, Daburu Gurenēdo) is a shoot hissatsu technique.
Inazuma Eleven 2: Kyoui no Shinryakusha
- "Kick the ball with both feet for twice the power in this mighty drop kick!"
In the anime, it was first used in episode 124 by Kito, but it was blocked by Endou's God Catch G2. Later it was able to evolve up to V2, in order to make it stronger, and it almost broke through God Catch.
It is mostly used just like how Grenade Shot is used. The user first kicks the ball with the right foot, followed by a kick from the left foot. The ball gets a blue energy. Finally, the user kicks the ball with both the feet and the ball heads towards the goal, leaving behind a blue energy in its path.
