A seal placed on the Fire Temple's gate, in order to defend against intruders from the outside world. The two statues placed on either side of the gate form a barrier. The seal can only be canceled by pouring in the Gift of the Hermit Group (仙族の才, Senzoku no Sai), special chakra peculiar to the shinobi monks (忍僧, ninsō).
