Mythical Beast Amber

**Mythical Beast Amber** (幻 (げん) 獣 (じゅう) 琥 (こ) 珀 (はく) , *Genjū Kohaku*?) is Hajime Kashimo's innate technique, later copied by Oboro Mu. When activated, it transforms his body in order to manifest any phenomena that can be created by electricity, which he converts from cursed energy.

## Description

Once activated, this technique reconstructs the user's flesh in order to manifest phenomena that can be created by electricity, which is converted from the user's cursed energy. However, since the technique causes the user's body to surpass the limits of a human, it can only be used once before their body collapses following the technique's conclusion. Though Reverse Cursed Technique can deal with the symptoms of the backlash, it cannot fully heal the effects of the technique, with Hajime callings the technique a “double edged sword”.

## Usage

### Hajime Kashimo

Hajime Kashimo released his innate technique when he confronted Sukuna to battle him after Satoru Gojo's death. The technique gradually transformed him, initially morphing his hair buns into horn-like hair buns and causing electricity to seep out of his eyes.

The technique continued to reconstruct him, coating his upper body and mouth in flame-like cursed energy while transforming his hand into sharp claws. This transformation granted him enhanced agility by increasing the activity of electrical signals in his brain, the ability to emit sound waves that are optimized and tuned to match the natural frequencies of materials to cause damage, and the ability to generate electromagnetic waves capable of vaporizing irradiated objects.

As the transformation progressed to fully transform his face, Hajime grew a third eye on his forehead that allowed him to analyze Sukuna's true form using X-rays. Later in the fight, after being launched away by Sukuna's strikes, Hajime demonstrated the ability to fire a beam of energy from his hands, though it was easily overpowered by an incantation-enhanced Dismantle from Sukuna.

### Oboro Mu

Prior to the Shinjuku Showdown, Oboro had patted Hajime on the shoulder, mimicking the ancient sorcerer’s technique, and having gained Kashimo’s 400 years of knowledge on the cursed technique, called it “exquisite”. Maki later scolded him about copying the technique.

After witnessing the demise of Hiromi Higuruma, and the less than stellar effect of Petty Decree on Sukuna, Oboro added a rule to Petty Decree, allowing him to activate the technique while still using Petty Decree. Upon activation, the technique gradually transformed him, initially morphing his king hair into spike-like hair and causing electricity to seep out of his eyes. With his cursed energy reinforcement, Oboro easily speed blitz the King of Curses, sending him flying as Oboro ordered Yuki to back Yuji up. The technique continued to reconstruct him, coating his upper body and mouth in flame-like cursed energy while transforming his hand into sharp claws. Oboro sent multiple electromagnetic waves capable of vaporizing irradiated objects at Sukuna, heavily damaging him and forcing him to use maximum Reverse Cursed Technique output to heal, only to be blitzed again by Oboro, with Sukuna realizing that not even reverse cursed technique could fully heal the damage he had taken.

As the transformation progressed to fully transform his face, Oboro grew a third eye on his forehead that allowed him to analyze Sukuna's true form using X-rays, calling the Calamity disgusting to look at, to which Sukuna replied the same went for Oboro, crediting Oboro’s use of Hajime’s technique was far better than the initial user.
