Soul Press

Soul Press (ソール・プレス; Sooru Puresu), also known as the Spirit Breaker is an unique technique developed by Kazuma Itori prior the events of The Worst Invader. First used against Koneko following her defeat at the hands of Ryuuta Bellemonth, it is the first and only display that supports his statement of being capable of using Senjutsu.

Summary
Once Koneko returns after her fight against Ryuuta on the house she finds that the invader has killed Raynare and is gone, with only Kazuma and Kaede Shirakawa remaining in the park. She tries to confront them, but seeing her in such a weak state Kazuma decides to put an end to her defiance by using Soul Press.

Abilities
This technique was created in order to prevent Kazuma's targets from keep fighting back and subdue to his desires. By channeling his life-force to the target's body, presumably via Senjutsu, Kazuma stimulates the nervous system of the said target, inducing a physical reaction which causes either intense pain or pleasure. For this ability to work, Kazuma has to make physical contact with the target; the kind of contact deciding which kind of sensation is triggered.

Soul Press causes the affected target to be unable to use any kind of special skill they possess for a a few seconds, as their magic reserves have taken damage too.

Trivia

 * The images used for the skill were taken from the manga Kono Shima ni wa Midara de Jaaku na Mono ga Sumu
 * Soul Press can be considered Kazuma's counterpart to Ichijou Tsukino's "special" spells (a.ka. Evil Aim, Level Zero, and Rule Breaker)
 * Its original concept was taken up from the anime and manga Soul Eater; a technique called Soul Menace. Usually used by Franken Stein or Black☆Star
