Who Is Saiken?

Registry summary

Saiken is the Six-Tails, a tailed beast in the shape of a vast, slime-covered slug. Kinder than most of the nine, it gave its jinchūriki Utakata his power willingly and never fought for control — a gentle creature dragged, like all its siblings, through the long story of capture.

Dossier · 03Origins

Background & Origins

Saiken is one of the nine tailed beasts, created when Hagoromo Ōtsutsuki divided the chakra of the Ten-Tails into nine creatures and named each.

Its form is an enormous bipedal slug — white with a faint blue tint, its whole body covered in a thick, slimy substance, with six long tails and optical tentacles for eyes.

Saiken is among the kindest of the nine beasts. Where many of its siblings are malicious or self-serving, Saiken is gentle — and it speaks, oddly, in a distinct regional dialect.

Saiken: Story Arc

  1. Born of the Ten-TailsDebut Arc · Kazekage Rescue

    Named by the Sage

    Saiken comes into being when Hagoromo Ōtsutsuki splits the Ten-Tails into nine beasts. Like its siblings, it is given a name and a self of its own.

  2. The gentle slug

    Kind among the fierce

    Saiken takes the shape of a vast slime-covered slug — and, rarer than its form, it is gentle. It carries none of the malice or self-interest that drives several of the nine beasts.

  3. Sealed into Utakata

    A willing bond

    Saiken is sealed within Utakata of Kirigakure. The two keep a decent, willing bond — Saiken giving Utakata access to its power, and never once fighting him for control.

  4. Utakata's exile

    A wanderer's road

    Utakata leaves Kirigakure a missing-nin during the Bloody Mist era. Saiken shares the long, drifting, homeless years of a host with no village left to return to.

  5. Captured by the Akatsuki

    Taken with its host

    Utakata is caught by the Akatsuki. Saiken is extracted from him and sealed into the Demonic Statue — and, with the extraction, Utakata's life is lost.

  6. Freed at last

    Out of the cycle of capture

    At the end of the Fourth Shinobi World War, Saiken is freed — released, at last, from the long cycle of being sealed, used, and taken.

Dossier · 05Combat

Abilities & Signature Jutsu

Saiken fights with what its slug body produces — corrosion. It can emit acidic substances, as liquid or as gas, that disintegrate whatever they touch, and it has an affinity for Water Release. It is also the source of the Soap Bubble Ninjutsu its jinchūriki Utakata built his whole style on. Beneath it sits a tailed beast's vast reserve of chakra.

Debut

Kazekage Rescue (Shippūden Start)

Saiken's Tailed Beast attribute is the giveaway — a column hit that only the nine tailed beasts on the board share. Its Village column reads None and its Ninja Rank reads None, and it has no clan and no Kekkei Genkai, so four columns turn grey at once. Its Nature Types column pairs Water with Yin. It debuts in the Kazekage Rescue era, mid-series, so the Debut Arc arrow can point either way.
