Powers and abilities

  • Superhuman Physical Characteristics
  • Enhanced Senses (Awareness: Uzuki is capable of handling Takamura, one of the strongest assassins who is capable of cutting down large structures with ease in a split second. This allowed him to rescue Gaku from him)
  • Multiple Selves (Type 1: Uzuki suffers from Dissociative Identity Disorder, a condition which developed as a way for Uzuki to deal with the trauma. This condition allows Uzuki to create multiple personas, changing his own characteristics to match those of a specific individual; these personas remain even after the person they're based on dies and are so accurate that even other people who were close to the person whom Uzuki is emulating have trouble telling the difference, an example of this would be Sakamoto and Nagumo who admitted that Uzuki's Rion persona resembled their old friend so closely that it's hard to distinguish between the real Rion and Rion-Uzuki. Since the death of Haruma, Gaku's unknown fate, and the seeming assimilation of the Takamura personality, Uzuki has become a jaded and uncaring individual, a shell of his former self. He seemingly no longer cares about his foster siblings, letting the Rion Akao personality influence his opinions on Tenkyu and is fixated on the goal of destroying the Japanese Association of Assassins no matter the cost. Uzuki can also mimic, if not outright replicate, the individual's mannerisms and capabilities as well. An example of this can be seen with his Takamura personality who not only mutters unintelligibly just as the real Takamura did but is also a master swordsman, being able to match and eventually cut down the real Takamura despite Uzuki having not shown any proficiency with wielding a katana up to that point in the series)
  • Technique Mimicry and Accelerated Development (Under extreme stress, Uzuki can adopt the persona and skills of people he knows. Uzuki spontaneously creates Takamura's personality inside his own head, gaining Takamura's exact mannerisms, physicals, and swordsmanship at point-blank range and catching Takamura off-guard. or the tactical, precognitive fighting style of Rion)
  • Analytical Prediction via Rion personality
  • Information Analysis via Rion personality
  • Status Effect Inducement (Shin's life flashes before his eyes when he reads Slur's mind)
  • Martial Arts (Similar to Sakamoto and Nagumo, Uzuki also attended the JCC and learned CQC)
  • Weapon Mastery (He primarily uses a versatile segmented sword-whip that functions as both a close-quarters blade and a mid-range whip. He later adds Takamura's katana to his arsenal after developing a persona based on the legendary assassin. His weapons are characterized by their ability to adapt to his unpredictable, split-personality fighting style)
  • Extrasensory Perception (Power Reading: He's able to sense the killing intent of Sakamoto)
  • Preparation (Uzuki is known for meticulously planned killings and the ability to analyze and exploit weaknesses in top-tier fighters like Kindaka and Takamura)
  • Explosion Manipulation (Can trigger bombers attached to his underlings)
  • Vehicular Mastery (Even though he stated he hates driving he is good at it)
  • Social Influencing
  • Leadership: He serves as the leader of a group of elite, formerly orphaned assassins (Gaku, Nagumo, etc) who aim to destroy the JAA.
  • Reputation: Early in the series, Uzuki is recognized as a mysterious figure responsible for wiping out over 30 JAA-related groups and killing over 100 professional assassins. He is infamous for leaving a large 'X' mark at every crime scene where he has killed his victims. He is considered one of the strongest characters in the series, often ranked alongside top-tier fighters like Takamura and Prime Sakamoto. He is viewed as the highest priority target, capable of causing significant chaos within the Japan Association of Assassins.
  • Stealth Mastery (Often appears behind people without them noticing. Moves behind Shin before he can react, then leaves the underground hallway before he can turn around)
  • Limited Body Control (His heart is on the right side of his chest so many people are deceived into believing they can kill him with a stab to the left side of his chest)
  • Aura (Overwhelming: Initially, he is portrayed as a calm, cold, and sadistic killer, capable of killing without remorse and paralyzing others with his bloodlust)
