In the secret rooms of the basement of the Tsuchikage's building, is where the ANBU holds there secret headquarters.
In one of the rooms, Naito has found to be a good spot to train in. The room is empty except for a bunching bag in one of the corners and a plant in the other one.
Naito moves slowly his limbs around in a specifik pattern and cordinates. He is trying to train chakra control and improve his bug techniques.
The bugs becomes restless pretty quickly beneath the clothings, due to the chakra which is being produced by Naito's movements.
