Formation Ino–Shika–Chō are formations used by the members of the Yamanaka, Nara, and Akimichi clans designed due to their long history of working together.
These formations are designed to use each member's abilities in the best way possible that complements the others'. This formation is usually done with flawless accuracy, which comes after working together - another testament of how close-knit the three clans are. This formation is not limited to any one specific technique of any of the clans but the respective clan members can use several of their respective clan's techniques in tandem to create different versions of this formation.
The name is a reference to a card combination in the Hanafuda card game, Koi-Koi; Inoshikachō uses the Boar (猪, Ino), the Deer (鹿, Shika), and the Butterfly (蝶, Chō).
