Summoning Technique

Biodata

Mechanics

• A summoning contract establishes a connection between the parties. Casting the technique uses that connection and chakra to bring the contracted target to the summoner 371 809.
• Blood commonly serves as the link that strengthens contact with a target. Mizuki uses his blood when summoning his poorly intelligent jellyfish to improve their connection and control 41 42.
• The standard hand seals can be bypassed with sufficient chakra control. Blood can also be omitted, though a distant target may then be impossible to contact 371.
• The chakra available to the caster limits what they can summon: a contract with a powerful beast alone is not enough to call it 94.
• Multiple ninja can contract with one summoned beast, and one ninja can contract with multiple beasts. Once a particular soul connection is severed, it generally cannot be restored 809.

Applications

Beast summoning

• Summoned beasts can provide combat support, transportation, scouting, surveillance, and help with traps 133.
• Mizuki summons transparent jellyfish beneath a river, then uses them alongside mist and genjutsu 96. He also summons Bota-kun, a giant bear developed for immense physical strength 141.
• A summoned beast's usefulness depends on its abilities and the caster's control. Naruto's attempt to summon Gamabunta instead produces a small toad, while Mizuki notes that the jellyfish's low intelligence makes them difficult to direct 42 140 141.

Communication and transport

• Marked summoned beasts can relay messages over long distances. Mizuki stations them near his original body and the Bootleg Jinchuriki so either side can summon one and receive information 116 124.
• Summoning and reverse summoning can move targets through space. Spatial marks can serve as positioning points, but opening and controlling a channel for teleportation is difficult 41 371.
• Mizuki combines summoning with sealing techniques and stored chakra for a long-range attack and emergency escape channel. Its first use nearly destroys the clone passing through it 33.

Objects and prepared techniques

• Item summoning includes Summoning: Rashomon, a defensive technique whose substantial cost limits its practicality 293.
• Storage techniques such as a Space-Time Warehouse are further applications of summoning principles 371 495.
• A prepared Reverse Summoning Technique can activate when conditions are met, though the Heaven and Earth Scroll example has limited chakra and range and is impractical in combat 373.

Contracts and research

Mizuki initially questions what powerful summoned beasts gain from helping humans. Studying Kakashi's ninja-dog contract, he finds runes that appear to collect the contractor's otherwise dissipating mental fluctuations. He later adapts this principle with the Soul Gathering Formation, gathering spiritual power from his summons to help balance the energy used in Sage Mode 42 47 148 155.

Mizuki compiles his findings into a scroll for Sakura. It covers beast contracts, item summoning, storage and sealing methods, and Summoning: Rashomon; he offers her access to his jellyfish and Bota-kun while leaving her free to seek another summon 495.

Limitations and exceptions

• Ordinary summoning fails between Mizuki and the Bootleg Jinchuriki after their contract identifies them as the same person rather than two individuals 42.
• The Animal Path can summon unusual beasts without forming conventional contracts and can call other Paths of Pain to its location 484.
• Mizuki counters the Animal Path's ability to summon the restrained Naraka Path away by combining a Binding Formation with Contract Seal effects 722.
