Summoning: Snakes (Fire)

Before a summon can be performed, a prospective summoner must first sign a contract with a given species. After this, they need only perform the hand seals, offer an additional donation of blood, and use the same hand they signed the contract with to summon the creature. The amount of chakra used during the summoning determines how big the summoned creature can be. Koharu can summon Kondai (Fire)
