These are pills in a capsulated form created by Magire and Kido Tsumiki. After the consumption of this drug the user gains a heightened transformation.
Overview
By collecting DNA samples left by Naruto Uzumaki after his battle with Sasuke in the Valley of the End, Kido and Magire were successfully able to create this drug. When activated the user gains a chakra cloak with tails that can range from one to nine tails. The tails are capable of being used as a shield deflecting kunai, taijutsu or ninjutsu. These tails are also able to manifest into Tailed Beast Chakra Arms.
Drawback
Though the tails can be used defensively the cloak that embeds the body leaves the user just as vulnerable with it as without. If the user is rendered unconscious the cloak will disappear.
