(All canon to the Naruto series.)

In this,Gaara met Naruto when they both and everyone else were teenagers.Gaara was since then protective of Naruto and would choke anyone on sand-💀..if they hurt Naruto or did something to upset him.

Right now,everyone is in the forest.They had Kakashi sensei going with them so that nothing would happen.

Skip.

A situation came up.Sakura was trying anger Gaara and she succeeded,he was angry.

Everyone else stayed at the side,not knowing if to interve.

Kakashi was just watching and observing.

Suddenly,Gaara raised his hand and a trace of sand was behind him,preparing to attack her.
