MC Abilities Before Reincarnation (No Superpowers Yet):

1. Extensive Martial Arts Knowledge – Possesses mastery over a vast array of martial arts, including those from anime, video games, real-life disciplines, and more. This allows the wielder to seamlessly incorporate and adapt various techniques in combat, making them highly unpredictable and versatile.

2. All-Rounder / Multi-Talented – Excels not only in combat but also in various other skills and disciplines.

3. Sixth Sense – Possesses heightened awareness, instinctively sensing danger, presence, and subtle changes in his surroundings.

Innate Abilities (From Birth After Reincarnation):

-Illusion

2. Poison Immunity – Unaffected by all forms of poison, from natural toxins to engineered venoms.

3. Gourmet Energy (Toriko) – Though hindered by normal food, it still accelerates injury recovery and provides a slight strength boost. However, when consuming Kirio Hikifune's food, its effects are fully unleashed, dramatically enhancing both recovery and physical power.

Abilities Upon Becoming/Awakening as a Fullbringer:

A. System Assistant

Provides information and some support, but cannot reveal anything beyond its capabilities. There are no quests, allowing the MC complete freedom.

B. Bleach:

1. Reiatsu Infusion (Spiritual Enhancement of Objects) – By channeling his Reiatsu into earthly materials, the MC can grant them unique properties beyond their original limitations.

Example: 

-Unlimited Power Supply – Infused devices (e.g., phones, camcorders, flashlights) never run out of battery.

-Free Signal Access – Phones and other communication devices gain unlimited signal reception, working even in areas with no service.

-Supernatural Recording – Camcorders and similar devices can now capture and record spiritual beings (Hollows, Shinigami, etc.), imprinting them onto physical media (e.g., VHS tapes, DVDs). This allows normal people to see and understand supernatural events.

-Spiritual Glasses – Regular glasses can be infused with Reiatsu, allowing normal humans to temporarily see spiritual beings as long as they wear them.

-Expanded Applications – Potentially applies to other items, such as radios (to hear spiritual voices), flashlights (to illuminate spiritual entities), and even tools or weapons for humans to interact with the supernatural.

2. Kaidō - Kaidō is a specialized form of Kidō that focuses exclusively on healing rather than offense or defense. Unlike Hadō (destructive spells) and Bakudō (support and binding spells), Kaidō has no known incantations, numbers, or named spells—its purpose is purely to restore injuries and replenish Reiatsu.

3. Seppa – By moving their hand in the same pattern as a trembling current and saying the phrase "let it be sand" (砂になあれ, suna ni na are), the user can reduce anything they touch to sand. This ability can be used in various ways, such as blasting through walls to create escape routes, sinking weapons or objects into the ground to render them useless, or softening falls by turning the landing surface into sand. Additionally, the user can perform Seppa with their feet and utilize it to create large clouds of sand for obscuring vision. It is particularly effective against stone and similar materials.

C. Ripple (Hamon) (JoJo's Bizarre Adventure)

Ripple (Hamon)

Ripple (Hamon) is a unique energy produced through controlled breathing, mirroring the positive energy of the sun. It flows through the user's bloodstream, radiating outward to enhance physical abilities and imbue objects with solar-like properties. This energy can be transferred into weapons, liquids, and even living beings, making them conduits for its effects. When applied offensively, it can burn and disintegrate creatures vulnerable to sunlight, while defensively, it accelerates healing and neutralizes harmful substances. Ripple users undergo rigorous training to refine their breathing techniques, allowing them to generate stronger and more precise energy waves. However, its effectiveness depends on sustained breathing, making the user vulnerable if their airflow is disrupted.

D. Total Concentration Breathing & Weapon Nichirin Blade (Color Black) (Demon Slayer)

1. Total Concentration Breathing

Total Concentration Breathing is an advanced breathing technique that maximizes a user's physical potential by expanding lung capacity, increasing oxygen intake, and accelerating blood circulation. This heightened state amplifies the user's physical traits, granting them superhuman strength, speed, endurance, and heightened mental acuity while still remaining human.

By maintaining Total Concentration Breathing, the user can enhance their reflexes, process information faster, and push their body beyond normal human limitations. Mastery of this technique allows warriors to fight at speeds too fast for the eye to track, generate immense force with each strike, and sustain themselves in prolonged battles without succumbing to exhaustion.

The most advanced form, Total Concentration: Constant, enables practitioners to maintain this heightened state indefinitely, drastically improving their overall fitness and combat effectiveness. This requires rigorous training, such as controlled breathing exercises and lung-strengthening techniques.

Additionally, Total Concentration Breathing enhances recovery capabilities, allowing users to slow the spread of poisons, clot wounds, and even mend internal injuries through focused breathing. More experienced users can perform Recovery Breathing, briefly steadying their breath to counteract fatigue and restore their body's mobility after extreme exertion.

In essence, Total Concentration Breathing transforms the body into a refined and efficient weapon, elevating its performance to superhuman levels while still operating within the realm of human limitations.

2. Nichirin Blades

Nichirin Blades are specialized swords forged from Scarlet Crimson Iron Sand and Scarlet Ore, rare materials that continuously absorb sunlight. This unique property makes them exceptionally effective against creatures vulnerable to solar energy. Their durability, sharpness, and ability to change color upon bonding with a wielder enhance their combat potential. When infused with Ripple energy, these blades become even more powerful, conducting and storing the energy for extended periods. This fusion amplifies their destructive capabilities, allowing strikes that burn and disintegrate foes while negating regeneration. The synergy between sunlight absorption and Ripple infusion makes Nichirin Blades the ultimate weapon against supernatural enemies.

Each Nichirin Blade undergoes a color transformation upon being drawn by its wielder, reflecting their affinity and combat style. This phenomenon earns them the name Color Changing Katanas. However, if the user lacks sufficient skill, the blade remains colorless.

Sword Name: Kokuyōken (黒陽剣) – "Black Sun Blade"

Sword Color: Black Nichirin Blade – A rare and enigmatic color, a black Nichirin Blade symbolizes the Resplendent and Eternal Sun. Black katanas symbolize mystery and power, Though little is known about its full significance, it is often associated with powerful warriors who wield immense potential. Black blades are believed to carry the essence of adaptability, allowing their wielder to master multiple techniques rather than being confined to a single fighting style.

Historically, wielders of black Nichirin Blades have been rare, and their destinies often shrouded in mystery. However, due to the sword's deep connection to the Sun it is speculated to hold unique properties.

This unique sword possesses the ability to regenerate from damage, restoring itself over time through the wielder's spiritual energy. Unlike ordinary weapons, its recovery is not instantaneous but relies on the user's willpower, Reiatsu, and the time needed to re-infuse it with energy.

When chipped, cracked, or even broken, the sword can gradually mend itself as long as its wielder remains alive and capable of channeling their spirit into it. The regeneration speed depends on the wielder's strength, emotional state, and connection to the blade. This ability ensures that, as long as its master endures, the sword will never truly be lost.

E. Total Concentration Hamon Breathing (Demon Slayer + JoJo)

Total Concentration Hamon Breathing is a fusion of advanced breath control and life energy manipulation, enhancing both physical abilities and supernatural prowess. By deeply expanding the lungs and accelerating blood circulation, the user fills their body with both oxygen and Hamon, creating an optimal state of heightened strength, speed, and endurance. Their muscles and bones become energized, allowing for superhuman feats while also radiating Hamon through every movement.

This technique enables the user to wield weapons infused with Hamon energy, making their strikes more lethal. Their breathing remains constant, maintaining peak performance while rapidly recovering from injuries and resisting poisons or fatigue. By continuously circulating Hamon throughout their body, they become an unstoppable force—agile, resilient, and radiating with the life force needed to counter any supernatural threat.

F. Haki (One Piece)

This mysterious power allows individuals to harness their spiritual energy for extraordinary feats. It is an ability that exists within all living beings, but only a select few can awaken and master it. Users of this power can tap into their willpower to achieve superhuman capabilities, enhancing both their physical and mental prowess.

There are three distinct forms of this ability, each granting a different advantage:

-Observation Haki – This ability grants the user an enhanced sensory awareness beyond ordinary perception, allowing them to detect the presence, strength, and emotions of others. It enables users to sense life forces even when they are hidden from view, track movements with pinpoint accuracy, and gauge an opponent's level of power. At more advanced levels, this ability provides a form of limited precognition, allowing users to anticipate incoming attacks before they happen. This heightened awareness gives them an immense advantage in battle, making it possible to evade strikes, counter enemy movements, and react with near-instant precision. With greater mastery, individuals can refine their perception to detect even the subtlest shifts in intent, foresee the flow of combat moments ahead, and maintain awareness of their surroundings even in complete darkness or obscured conditions.

-Armament Haki – This ability allows the user to manifest their spiritual energy as an invisible armor, significantly enhancing both offensive and defensive capabilities. By coating their body or weapons with this energy, they can strike with far greater force, bypassing conventional durability and even damaging entities that would normally be impervious to physical attacks. Defensively, this armor serves as a protective barrier, reducing the impact of incoming blows and making the user more resistant to damage. With greater mastery, this energy can be hardened into a visibly darkened state, increasing its durability and offensive potential even further. At its most advanced level, the user can project this energy outward, enabling them to strike targets without direct contact, breaking through defenses and inflicting internal damage. This makes it an incredibly versatile power, effective in both close combat and ranged confrontations.

-Supreme King Haki – This rare and powerful ability allows the user to impose their will upon others, overwhelming those with weaker spirits. When unleashed, it can cause intimidation, paralysis, or even unconsciousness in those unable to resist its sheer dominance. At a more advanced level, this power can be infused into the user's body or weapons, greatly amplifying their attacks. This infusion grants devastating offensive potential, allowing strikes to bypass defenses and deal massive damage, similar to an enhanced physical reinforcement technique. However, only a select few individuals possess the strength and talent to wield this ability at such a level. Unlike other abilities that can be developed through training, Supreme King's Will cannot be learned or awakened by ordinary means. It is an innate trait, possessed only by those born with the presence and spirit of a ruler. Those who manifest this power are considered to be chosen by fate, standing above others as true conquerors.

Mastery over this power sets individuals apart as formidable warriors, with the strongest wielders standing at the pinnacle of combat. Though it originates from inner strength and determination, only a select few are able to unlock its full potential.
