Cursed Spirit Manipulation

Cursed Spirit Manipulation is a type of technique where the user can summon and manipulate naturally formed Cursed Spirits for a desired purpose or purposes. The Cursed Spirit Manipulation user cannot create Cursed Spirits, but instead relies on a pool of Cursed Spirits they capture. Known possessors of this technique are Suguru Geto and an unknown individual that is currently possessing Suguro Geto's body.

Description
Cursed Spirit Manipulation requires that a Sorcerer capture, exorcise or purify, and then store and collect the Cursed Spirits they wish to use. The Sorcerer first must exorcise or purify the Cursed Spirits by defeating it. Once the Cursed Spirit is defeated, the sorcerer forms a black ball in their palm, which sucks in the Cursed Spirit. They then orally consume the ball through their mouth. The Cursed Spirit Manipulation user can then summon and control this Cursed Spirit at will.

Strengths

 * The user is able to use a variety of different Cursed Spirits, making them incredibly versatile in all areas of combat.
 * Given that the only prerequisite for the technique is that the sorcerer must exorcise and then consume the Cursed Spirit, provided the sorcerer sufficiently outranks the Cursed Spirit, they can take on a Cursed Spirit with virtually no conditions.
 * There appears to be no limit on the amount of Cursed Spirits a Cursed Spirit Manipulation user can collect. The maximum amount seen stored is 4,461 after Geto released 2000 to attack Tokyo and Kyoto

Weaknesses

 * The collection process is disgusting, as the black ball containing the Cursed Spirit is said to taste like a rag used to wipe up vomit.
 * Where there is no significant rank difference between the Cursed Spirit consumed and the sorcerer consuming it, the sorcerer may have to take on conditions of some form in order to obtain the Cursed Spirit. It is unclear what these conditions are or how they form.
 * The Cursed Spirit Manipulation user can only consume and manipulate naturally forming Cursed Spirits, not any Cursed Spirits created by other sorcerer's Cursed Technique, for example like shikigami.

Side Effects

 * The Cursed Energy of Cursed Spirit Manipulation users is markedly different from other sorcerers. It is theorised this is due to the cursed energy of the various different Cursed Spirits they have consumed, but no further evidence has been provided to support this.
 * It is unclear what happens to the Cursed Spirits collected by a Cursed Spirit Manipulation user when that user dies.

Suguru Geto

 * Cursed Spirit Manipulation Technique Maximum Uzumaki: The Maximum technique of Cursed Spirit Manipulation, it 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, it's versatility 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 or higher as their technique gets extracted.
