Tetsu-Fuma Formation

This is a defensive collaboration technique developed by Hiroki and Minato in order to protect Yanoi or other injured shinobi.

Hiroki and Minato stand almost back to back on either side of the person they're trying to defend. Hiroki deploys a detection barrier around them in order to sense incoming attacks or enemies. He then relays the information to Minato to either send an attack at the approaching enemy, or to intercept the attack. However Hiroki also uses his chakra shield jutsu to block the opponent's attacks.
