Cursed Ability (Jutsushiki):
"Dismembered Sanctuary"
Allows the user to manipulate Ryomen Sukuna's "slicing and dissection" technique, but with a different name and approach: instead of causing chaotic destruction, it creates cuts with refined, surgical precision.
Its cursed blades are generated in the air, in any direction and shape, and can even heal minor wounds by reversing the cut-a technique refined compared to the original style.
Advantages: Great versatility in mid- and long-range combat, precise damage control, and medical support.
Weaknesses: High cursed energy consumption with continuous use and difficulty dealing with defense amplification techniques.
Cursed Reverse Technique:
Yes-Used to heal both one's own and others' wounds. Its control is as refined as Shoko Ieiri's, making it one of the few capable of rapidly treating extensive internal damage.
Domain Expansion:
Name: "Silent Garden of Judgment"
Description:
Upon activating your Domain Expansion, the environment transforms into a silent field of white stone and red flowers, with floating blades slowly hovering around.

Unlike the chaos of Sukuna's Malevolent Shrine, here time seems to slow down, and any enemy within the domain is cut by imperceptible lines of judgment-each strike is based on the sins or curses of the target's soul, becoming unavoidable if the enemy has hostile intent.
--
Combat Style:
Melee, medium, and long range with cursed technique.
Balances precise attacks with mobility and support.
Cursed Weapons/Tools:
Gloves cursed with runes that amplify the precision of cuts and allow the conjuration of blades with the movement of the hands.
Barrier or Curtain Technique:
Yes - Can create camouflage curtains and defensive barriers with great efficiency, used to protect civilians or keep battlefields isolated.

Cursed Ability (Jutsushiki):
Name: "Nullification Absorption"
Description: Riku can absorb cursed energy from the environment or directly from any cursed being (including sorcerers and curses) by touching them.
This energy is converted into physical strength and endurance.
When absorbing energy directly from an opponent of the same or lower level, he can temporarily neutralize the enemy's active cursed technique.

Weaknesses: The technique requires contact or proximity and does not work against higher-level techniques without strategy. It can overload the body if absorbed too much.
Reverse Cursed Technique:
Yes.
He uses the reverse technique to heal internal injuries caused by energy overload and strengthen his muscles, remaining in the fight even after significant damage.
Domain Expansion:
Name: "Crushing Void Core"
Description: A dark, enclosed space with crystals floating around that gradually drain all cursed energy from the opponent.
Within the domain, Riku can freely absorb the energy drawn, making the opponent unable to use cursed techniques, becoming easy prey for physical attacks.

The environment is suffocating and gives the sensation of being crushed by the sheer pressure of cursed energy.
