Earth Release: Heaven-Piercing Summoning Technique

The Doton: Tengen Toppa Kuchiyose no Jutsu (Kanji: 土遁 ・ 天眼突破口寄せの術; English: Earth Release, Heaven-Piercing Summoning Technique) is the only means through which Kamina, the personal summon of Oshiishi Kamizuru, allows himself to be summoned.

Being summoned through this jutsu allows Kamina to continuously harden himself with any chakra that happens to be transferred to him, thus allowing Kamina to augment both his already extreme durability and the unstoppability of his drills.
