Chakra Suppression Technique

This technique allows the user to suppress their or their allies' chakra to the point that it becomes completely undetectable. This makes it impossible for sensor type shinobi to track them via chakra. This technique is very useful in the sense of allowing the user to infiltrate the enemy's ranks undetected.

Drawbacks
The downside of this ability is that since the user suppresses their chakra, they are unable to use ninjutsu.

Note
In the First Part Mina Uzumaki is able to use this technique, but only to suppress her own chakra.
