→Jiraiya uses his left hand. Naruto uses his right hand for the contract. In any case, the user's blood is essential.

Through a blood contract, fantastic creatures can be called forth!!

This is a kind of space-time ninjutsu, allowing the user to summon any living being with whom they signed a contract in blood, at any time and place they desire. The summoned creature will obey the user with its life, helping in every situation, whether it be fighting or fleeing. The user smears their own blood on the hand they signed the contract with and kneads chakra by doing handseals. Then by turning the palm of that hand to the place they want to summon, they call forth a subordinate they can rely on.

Contract
↓It's not a technique someone of genin-level should use. However, Naruto successfully signed a contract.
