The Human Bullet Yo-Yo is the technique derived from "Formation E" (フォーメーションE, Fōmēshon Ī) used by the 16th generation of the Ino–Shika–Chō trio.

The mechanism behind the technique.

In performing this technique, Chōji firstly increases his size, while Shikamaru connects their two shadows. At the same time, Ino detects any enemies in the immediate vicinity and transmits this information directly to Shikamaru. As Chōji begins to attack with the Human Bullet Tank technique, Ino continues to track their opponents so that Shikamaru can perfectly direct Chōji's movement by manipulating the shadow. How this formation functions and its overall appearance is akin to a person using a yo-yo, albeit in a destructive manner.


  • In the telepathic dimension of Ino and Shikamaru, this technique when shown as a silhouette looks similar to Ultraman, a superhero who controls a huge yo-yo which is connected with his middle finger and uses it to smash his enemies.
