The Multi-Size Technique is a secret technique passed down in the Akimichi clan that increases the user's body size by converting their calories into chakra.


The user can freely alter their size at will when using this technique, and can use it for an extensive period of time. A common application of the techniques gives the user a very round appearance by mostly increasing the size of the abdominal section, which is done in order to use the Human Bullet Tank technique. Other, more common applications increase the size of the entire body, turning the user into a giant.
