Keshin

Keshin (化身, "Avatar") is a new feature in the Inazuma Eleven GO Universe that are similiar to a Hissatsu. Hissatsu techniques can be performed using Keshin.

Info
It's described as the spiritual energy people create, which is usually invisible to the eye. But when that power is mastered, it reveals itself in a visible form. It can also greatly reduce the stamina of the user,causing severe fatigue, as shown when Shindou passed out of exhaustion after using one. It is also shown that if a keshin is beaten by another keshin the user will need to wait some time to use it again.

It is also notable that SEEDs are the only ones authorized by the Fifth Sector to use a keshin, though there are some keshin users who aren't SEEDs. just like Shindou Takuto and Matsukaze Tenma.
