Maximum: Uzumaki

Maximum: Uzumaki (「うずまき」) is the Maximum technique of Cursed Spirit Manipulation.

Description
Maximum: Uzumaki combines the cursed spirits the user has absorbed into one and uses it as a powerful attack of super condensed cursed energy. While at glance it seems to negate cursed spirit manipulation's main advantage, its wide arsenal of cursed techniques due to losing access to the curses used in the attack, its true potential is revealed. When used on cursed spirits of semi-grade 1 ranking or higher, Uzumaki extracts their innate cursed technique, allowing the user to keep the techniques.

Suguru Geto
Suguru Geto used this technique against Yuta Okkotsu and Rika during the Night Parade of a Hundred Demons by combining all of 4,461 cursed spirits in his arsenal. However, all of the cursed spirits are exorcised by Rika's cursed energy beam of "true love".

Kenjaku
After absorbing Mahito, Kenjaku used this technique against Kasumi Miwa by combining unknown amounts of cursed spirits (not all) including Mahito. The attack left a huge crater on the ground, however Kasumi is saved by the arrive of Atsuya Kusakabe and Utahime Iori. Thanks to Uzumaki, Kenjaku extracted the innate technique of Mahito and achieved Idle Transfiguration.

Trivia

 * This technique's design is a reference to Junji Ito's Uzumaki.
