Cursed Energy

Biodata

Power Progression

Nature and Rules

• Cursed Energy is negative energy. Reverse Cursed Technique multiplies this negative energy into positive energy, enabling healing and purification effects 41.
• In the jujutsu world, a person’s Cursed Energy reserves and innate technique are generally determined at birth; major post-awakening growth is considered extremely difficult 2.
• Ordinary people possess Cursed Energy, though their levels may be too low to perceive or handle Cursed Spirits 4 12.
• Attacks lacking Cursed Energy ordinarily cannot kill Cursed Spirits, although positive energy produced through Reverse Cursed Technique can purify them 41 102.
• Jujutsu sorcerers and Cursed Spirits commonly judge an opponent’s threat level by their Cursed Energy output. This can be misleading against fighters such as Morien, who can convert his energy into other systems, or Maki, who possesses almost none 19 20.
• Morien’s synchronized Cursed Energy can transform into Spirituality and Path Power, while those energies can also be converted back into Cursed Energy 4 24.
• Cursed Energy and Path Power can be fused into a shared energy supply. This gives Morien effectively inexhaustible reserves in principle, though the amount he can release at once remains limited by his output capacity 93.
• This conversion does not extend to every foreign energy system. Morien cannot directly convert Path Power into Mana for spirit arts, leaving the available Lesser Spirits and their Mana as a practical limitation 137.

Applications

Reinforcement and Release

Released Cursed Energy appears around Morien as blue flame-like aura; when infused with Propagation and Elation, it becomes blue-violet and particle-filled 4 14.

• Reinforces the body’s strength, speed, reflexes, and durability 4 31.
• Covers the body as a defensive coating capable of deflecting bullets from period firearms 4.
• Allows physical attacks to affect Cursed Spirits and other supernatural targets 19 20.
• Can be concentrated into explosive movement or close-combat strikes 4 20.
• Can be discharged as destructive ranged blasts. After observing Ryu Ishigori, Morien learns to reproduce the latter’s Cursed Energy Discharge as a spell and engages him in a direct beam clash 93 99.
• Ryu Ishigori demonstrates that sufficiently refined discharge can be released from any part of the body, used for recoil-based movement, or condensed into the high-output Granite Blast 95 97.

Resonance Curse Technique

Resonance transmits Morien’s voice directly into a target’s mind. Its defining exchange is near-certain comprehension by living beings regardless of nationality or species, in return for lacking direct offensive force 2 14.

• Initially has a straight-line range of barely over 100 meters, consumes heavy amounts of Cursed Energy, and cannot be maintained for more than three minutes 2.
• Cannot create sound-based attacks or amplify speech into “sound bombs” 2.
• When combined with Propagation, Morien replicates his words within a target’s mind, flooding Haruta Shigemo with overlapping messages and overwhelming his ability to process them 14.
• Can interfere with instinct-driven Shikigami by making Morien’s words feel like their own thoughts; Dagon’s summons become confused or attack their master 21.
• Morien uses synchronized commands of “Stop” to introduce a competing instinct into Toji Fushiguro’s mind 24.
• A Binding Vow makes the technique permanently active at low power around nearby beings, at the price of continuous energy consumption and speaking without opening his mouth 45.
• Resonance can command beings beyond ordinary human targets. In Lugunica, Morien uses it to call every Lesser Spirit within roughly half the royal capital to his side without chanting 137.

Swarm-body and Distributed Existence

Following his Black Flash breakthroughs, Morien can apply Resonance to himself and treat his body as a collective of connected living parts rather than a single fixed organism 48.

• Morien can divide into butterflies, beetles, flies, bees, worms, spiders, centipedes, and other insects while retaining one unified consciousness 48.
• The swarm can travel collectively, with flying insects carrying nonflying insects, clothing, and equipment before Morien reconstitutes a body 48.
• He can disperse into mosquitoes to escape physical restraints and reform behind an opponent for a counterattack 70.
• In later worlds, Morien’s insect-composed body allows attacks to pass through him or damage only his clothing rather than inflict conventional bodily harm 136.

Binding Vows and Energy Conversion

Binding Vows exchange a self-imposed limitation for a compensating benefit 14.

• Morien can convert all Cursed Energy into Spirituality, preventing Domains that target Cursed Energy from recognizing him as a valid target 19.
• This conversion leaves allies or summons behind if they cannot perform the same transformation; Rabbit Escape remains inside Dagon’s Domain when Morien exits 21.
• Against Toji, Morien vows to reduce his Cursed Energy to zero for an hour in exchange for three minutes of comprehensive physical enhancement equal to his then-current Cursed Energy 24.
• By immediately converting the vow-enhanced Cursed Energy into Path Power, Morien retains combat output while technically paying the vow’s cost 24 25.
• Jujutsu barriers, including the Culling Game’s colony barriers, rely on the concept of Cursed Energy. Morien can enter or leave by reducing his Cursed Energy to zero through conversion 92.
• Morien uses Glintstone energy to establish a renewable power source within Rabbit Escape. The resulting Glintstone Rabbit can replenish itself without relying on ordinary Cursed Energy intake 64.

Black Flash

Black Flash is a high-level phenomenon that can draw out 120% of a user’s potential and deepen their understanding of Cursed Energy and their innate technique 24 48.

• Fortune-Collecting Mother Insect triggers Black Flash against Cursed Spirit Haruta, gaining a deeper understanding of her miracle-collection and propagation abilities 23 24.
• Morien and Toji land Black Flash simultaneously during their battle, with the collision shattering nearby windows and damaging surrounding buildings 25.
• Morien’s Black Flash in the fog-covered forest annihilates a mounted creature and creates a crater in a cliff wall 47.
• Repeated Black Flashes allow Morien to comprehend Resonance well enough to divide his body into a swarm 48.
• While battling Mr. Z and a Shadow World appendage, Morien recreates the required near-death combat state and lands a Black Flash powerful enough to blast through half of the appendage’s palm 82.

Reverse Cursed Technique

Reverse Cursed Technique creates positive energy from Cursed Energy, allowing healing and purification 41.

• Morien’s white positive-energy flames can heal wounds and purify Cursed Spirits 41.
• He uses the technique to restore Thops’s exhaustion, malnutrition, hidden injuries, and most damage caused by Glintstone research 50.
• Qiu Si develops Reverse Cursed Technique Emission through the shared knowledge of the Swarm Network 41.
• Morien channels positive energy into Mahito’s double after making contact. The double severs its own arm to keep the purification from spreading through its body 72.
• Insect Brood linked to the Swarm Network can use Reverse Cursed Technique at a basic level. Their positive-energy assault helps kill Kurourushi after Fortune-Collecting reduces its luck to zero 100 102.

Cursed Technique Reversal

Cursed Technique Reversal uses positive energy from Reverse Cursed Technique to invert an innate technique’s normal effect 43.

• Morien’s Resonance Curse Technique reverses from voice transmission into Mind Reading 43.
• Mind Reading works on targets regardless of strength, but requires physical contact rather than Resonance’s remote delivery 43.
• The contact requirement makes it impractical against stronger enemies who cannot safely be approached 43.
• Each successful contact grants Morien five seconds of access to a target’s thoughts and intentions; further contact refreshes this duration 65.
• During his battle with Aoi Todo, Morien uses Mind Reading to perceive Todo’s feints, Cursed Energy changes, and intended Boogie Woogie swaps before they occur 65.

Hollow Technique

Hollow Technique: Fleeting Illusory Great Dream is an advanced mental technique created by combining Cursed Technique Lapse: Mind Message with Cursed Technique Reversal: Mind Reading 72.

• Activation requires Morien to touch and mark the target, form a hand sign, chant, and speak the target’s name within five seconds without interruption 72.
• The technique exiles the target’s consciousness into an infinitely extended instant. The victim remains aware but cannot move, perceive external stimuli, or advance to the next moment 72.
• Its effect is psychological rather than temporal: a single instant in reality may become centuries or longer in the victim’s subjective perception 72 172.
• Mahito’s double mentally exhausts itself and collapses after experiencing the extended isolation, despite initially believing Morien’s Cursed Energy would eventually run out 72.
• Mr. Z partially breaks through the technique by suppressing conscious thought and relying on his absolute instinctive faith in the True Creator 81.
• Taoxiang later uses the technique against Capella, inflicting hundreds of millions of years of subjective isolation and destroying her mind without immediately killing her regenerative body 172.

Interaction with Domains

• Domains can apply guaranteed-hit effects by locking onto Cursed Energy; Dagon’s Domain automatically targets all beings within it who possess Cursed Energy 19.
• Converting Cursed Energy into Spirituality prevents this lock-on, forcing summoned attacks to manifest physically before they can harm Morien 19.
• Morien’s permanently active Resonance is compared to a Simple Domain in its constant area of influence, but it cannot neutralize a Domain’s guaranteed-hit effect 45.
• Within a closed Domain, Morien can safely draw upon the limited Wish Power of its occupants without risking contamination from a wider population 21.
• Morien can similarly reduce his Cursed Energy to zero to pass through Fortune-Collecting’s Domain barrier without triggering its normal effects 101.
• Morien’s Domain Expansion: Dream of a Mayfly is not restricted to Cursed Energy targets. Because he can convert among Cursed Energy, Spirituality, Path Power, and Mana, its guaranteed-hit effect can lock onto targets possessing any energy system he has mastered 84.
• During the Sendai Colony’s fourfold Domain clash, Dream of a Mayfly remains after the other competing Domains collapse, before Morien dismisses it himself 101.

Documented Practitioners

• Morien — Uses Cursed Energy alongside Spirituality, Path Power, Propagation, Elation, Monsterification, and Binding Vows; his unusual conversions make his output difficult to assess conventionally. Jujutsu Headquarters later recognizes his Special Grade combat power while declaring him a Curse User 4 24 25 90.
• Fortune-Collecting Mother Insect — Lands Black Flash and uses the resulting insight to improve her miracle-fueled propagation. She later inherits Swarm Network knowledge, deploys Reverse Cursed Technique-capable Insect Brood, and manifests her own Domain Expansion 23 24 100.
• Qiu Si Mother Bug — Contributes to Reverse Cursed Technique research through the Swarm Network and inherits a portion of Morien’s Cursed Energy 40 41.
• Toji Fushiguro — Though originally without Cursed Energy, his resurrected vessel possesses it; a Black Flash lets him access the core of his body and briefly regain sanity 25.
• Aoi Todo — Uses Cursed Energy to operate Boogie Woogie, reinforce the objects within his Simple Domain, and execute New Shadow Style techniques such as Batto 65.
• Ryu Ishigori — Possesses extraordinarily high Cursed Energy output and the simple but devastating Cursed Energy Discharge technique, including Granite Blast 93 95 99.
• Glintstone Rabbit — A former Rabbit Escape shikigami whose Cursed Energy is fused with Glintstone-derived magical energy, creating a self-sustaining crystalline lifeform 64.
• Taoxiang — Uses Hollow Technique: Fleeting Illusory Great Dream against Capella, subjecting her consciousness to an immeasurable subjective imprisonment 172.
