Harvest (ハーヴェスト, Hāvesuto) is a block hissatsu technique.
Inazuma Eleven AC: Dream Battle
It was first used in episode 77 in order to steal the ball from Toramaru and it was used successfully. Harvest is originally a hissatsu of Senbayama but was never used in the anime. Makiya probably learnt this hissatsu from his teammates when he came to Neo Japan.
Inazuma Eleven 3: Sekai e no Chousen!!
The manual for Harvest can be bought for 3800 Nekketsu points at Cotarl's hissatsu store.
The user and their teammate are sliding to the ball. When they come close, blue lines appear and steals the ball from the opponent. Then the user leaves with the ball.
