Resonance

Resonance (り) is a move used by Nobara Kugisaki utilizing her Straw Doll Technique.

Description
This technique applies cursed energy to the user's target using the straw doll as an effigy.

The user will generally use one body part of their target to create the link and then use resonance to apply damage to more critical appendage of the opponent's body. For example, by placing a curse's severed arm on the straw doll and striking it with a nail using a hammer, the nails can be used to pierce the targeted curse's heart.

The effectiveness varies depending on the opponents skill level, the targeted body part, and the strength of the connection to the user's target. If a link is made to multiple opponents, Resonance will injure them all at the same time. It is also works on inanimate objects and can disrupt someone else's control over them.

Usage
Resonance is Nobara's signature move and her go to when exorcising weak curses. She uses it to stop curses from fleeing, as she can exorcise them no matter where they are as long its connected to her straw doll.

Using a single line of brush from Momo's broom, Nobara was able to use Resonance to disrupt the third-year girl's control over her flying broom.

While infected with Rot Technique Maximum: Decay, Nobara could pierce herself with her nails and inflict damage on both Eso and Kechizu. This was due to their connection to her blood via the aforementioned Rot Technique.

Resonance proved to be the perfect countermove for Eso's Decay, as she used it over and over again to stun both brothers until Eso was forced to deactivate his technique. When Eso attempted to flee, Nobara used Resonance on his severed arm to injure him and stop his escape.

Mahito initially believed Nobara would have no way to hurt him in their fight, as traditional techniques cannot injure his soul. However, by striking Mahito's body with Resonance she could attack his soul directly. This greatly injured Mahito, who immediately considered her his natural born enemy just like Yuji Itadori.
