## Abilities

**Overall Abilities:** From the start, although not a part of the Demon Slayer Corps, Fujii was able to catch Giyu Tomioka, the Water Hashira off guard. After starting his training in the Thunder Breathing, he has become strong enough to take on multiple demons including a former Lower Rank 6, Kyogai. After recalling the Unknown fire, he learned from his father as a child, he would've defeated Rui, Lower Rank 5, if Rui hadn't cut off his own head prior. After awakening his Demon Slayer Mark and training even further, Fujii has proven to be able to hold his own against even the Upper Rank like Akaza, even comparing his strength to that of a Hashira.

### Physical Abilities

**Immense Strength:** As a Demon slayer who spent four years perfecting his physical prowess, Fujii possesses amazing physical strength, being capable of swinging his katana at speeds faster than the eye can see incessantly and terrifying accuracy while engaging in combat.

**Immense Speed & Reflexes:** Fujii possessed great speed and reflexes that even a trained and gifted Demon Slayer like Tanjiro couldn't perceive or register. Fujii could even cause tremors to the ground and nearly launching a people off the train by running at speeds faster than the eye can see.

I**mmense Stamina & Endurance:** Fujii displayed superhuman stamina and endurance during his battles.

### Mental Abilities

**Tactical Intellect:** As a swordsman who came from a lineage of Flame Hashira, Fujii had access to generations of combat knowledge and tactics as well as training from previous Flame Hashira, like his father, Shinjuro Rengoku. During the battle against Akaza, he displayed keen judgement.

### Supernatural Abilities

* **Transparent World:** Like his father, he gained the ability to foresee the opponent's attack while showing no battle spirit and sense of blood-lust, gaining immunity from anyone who can sense these. In this state, his movement intuition and evasion speed increase dramatically

### Miscellaneous Abilities

* **Enhanced Senses:** Like all skilled Demon Slayers, Fujii has senses enhanced beyond that of regular humans, being able to detect and track demonic presences and fight with incredible precision and efficiency.

* **Indomitable Will:** Fujii has an undaunted spirit, Ever since he was a child, he has inculcated indomitable will and passion in himself due to his promise to his late mother.
* **Enhanced Hearing:** Fujii has had a heightened sense of sound even before he underwent sword training. It is strong enough for him to hear the 'line of interval'—the slight pause in an enemy's movement which allows him an opening in which to strike—and distinguish between species, as well as their approximate position. After training this skill during his time as a Demon Hunter, Fujii has acquired the ability to hear emotions as well as track objects, humans and demons over long distances.

### Demon ability

**Blood demon art, Demonic Transformation:** When Fujii is in a dire situation, he can transform into a berserk-like state, with the demon slayer crests, that appear as Speed lines, circle his body, his veins popping out. This form enhances Fujii's fighting ability, at the cost of him becoming more demon-like, including the need to feed on human blood. So far, the only way he could revert back to normal is to have someone he loves hug him. During the Demon Slayer's fight against Hantengu, Fujii manages to control this form at will.

**Sunlight Resistance:** During their battle against Upper Rank 4, Hantengu, Fujii developed immunity from sunlight, now being able to completely walk and go about in the daytime without being burnt to ash, unlike his fellow demons.

## Fighting Style

**Master Swordsman:** As he is a Hashira of the Demon Slayer Corps, FujiiTaiyō is one of the most powerful and skilled swordsmen in the entire organization. His mastery of the blade is best showcased during his battle with Akaza, in which he is able to hold his own against the Upper Rank even when gravely injured.
