Construction

Construction is Mai Zenin and Yorozu's innate technique. It allows to construct something from nothing using vast amounts of cursed energy.

Description
Construction allows the user to conjure an object from nothing. Unlike creating objects within a Domain, things constructed by this technique will not disappear once the spell has finished. However, creating something from nothing uses an immense amount of cursed energy, which results in harsh backlash on the user's body.

Mai Zenin
Mai developed this technique and hid it from her twin sister, Maki during their upbringing. She used a revolver in battle, so after shooting six shots against Maki it appeared that she had ran out of bullets. However, the construction allowed her to load another cursed energy charged bullet into her revolver. This surprise attack was meant to take her opponent off guard and finish the fight.

Mai's limit was one bullet per day, but this drained what little cursed energy she possessed, resulting in physical backlash such as a nose bleed. After being cut open by her own father, Mai decided to use construction to give her sister Maki a fighting chance. Mai was aware the backlash would kill her, but she used that opportunity to take all the cursed energy between the twins with her. Mai sacrificed her life to give Maki a body of steel that has escaped from cursed energy by utilizing construction to create a large broadsword.

Yorozu
Yorozu was a Jujutsu Sorcerer from ancient times and was born in the same era as Sukuna. Much like with Mai, Yorozu’s Innate Cursed Technique allowed her to create any matter by using her Cursed Energy as long as she has some understanding and information on whatever matter she desires to create. As shown Yorozu uses this technique to create Shadow Metal, a liquid like substance that possess the quality of liquid, metal, and shadow that Yorozu could control and shape at will to take on various forms for both defense and offense.

However, much like with Mai’s, the cursed energy efficiency of her technique was severely lacking and was not energy efficient for battle despite her own cursed energy reserves not falling short to the other most powerful Sorcerers of that era, with the rate of her cursed energy consumption eating more of her reserves than necessary and put her in many difficult situations in numerous battles.

This caused Yorozu to feel great frustration as she tirelessly researched to resolve this problem. Eventually upon hearing of a rumor of how a butterfly could fly across the sea and how a hornet is able to to fly 25 Li(100 Kilometers) in a single day, Yorozu slowly started to get a hint to solving her cursed technique’s weakness. Realizing the energy efficiency of a insect’s body, such as their ability to lift something several times their weight and mass and the immense jaw, jumping and speed strength some insect species possessed that should be impossible by their small sizes, Yorozu came to believe that creating an Insect Armor that incorporated the physical aspects of various insects using her cursed technique more than resolved the energy-inefficiency of her Construction Technique. Allowing her to fight on par with and overpower some of the most powerful Jujutsu sorcerer’s of the Heian Period, with her successfully defeating the Five Void Generals, a subjugation unit on par with the Sun, Moon and Stars unit led by Takako Uro using her Insect Armor and thus causing the Fujiwara Clan to begrudgingly acknowledge her power.
