Powers and Abilities

Kendō: When she was younger Naoto took martial arts lessons with Thomas, mostly because she wanted to remind herself of home. As such she has some skill with a sword. She prefers linked movement and thus uses practiced kata.

Human Abilities


Bitchslap (雌非難, Mesuhinan) is the name of Naoto's Fullbring, which is manifested from the bracelet she wears.

  • Focus: The focus of Naoto's Fullbring are her matching bracelets on each of her wrists. It is classified as a Caster-type because of the special ability it grants and also because she lacks a physical weapon.
Special Ability: Whenever Naoto makes a punching motion an ethereal limb appears to mimic the motion; which possesses strength many times greater than Naoto's own. The limb appears from a rift in the air away from Naoto's actual position, enabling her to attack at range. She can also control the size of the summoned limb, as demonstrated when she used it to slap Thomas at range.
  • Enhanced Strength: The ethereal arm possesses immense levels of physical power, and can easily demolish buildings with a single motion.

Shinigami Abilities


Ryūjōmaru (竜条丸, Dragon Brander). Naoto's zanpakutō has light pink hilt wrapping, as well as a bronze circular guard with four inward curves. She keeps it hidden within a black violin case which dangles from her shoulder.

Ryujomaru forms

The three forms of Ryūjōmaru. From left to right: Speed, Technique, and Power.

  • Shikai: Its release command is "Flash" (閃け, Hirameke), which Naoto follows with an additional command of "Power" (威勢, Isei), "Speed" (急ぎ, Isogi), or "Technique" (術, Jutsu). The form and abilities alters depending on the term called, and holds some relevance to attack, evasion, and strategy.
  • Power is the form of Ryūjōmaru's power that is aligned with brute force strength. It resembles a scimitar-esque sword with a wider blade than what is normal, and a decorative hand guard and hilt set with exquisite gold markings, with a dark blue theme.
  • Speed is the form of Ryūjōmaru's power that is aligned with speed and dextrose movement. It resembles a blue gauntlet that rises up to her elbow with exquisite gold markings, and two curved blades parallel to each other. From the knuckle forward it resembles a regular katana blade.
  • Technique is the form of Ryūjōmaru's power that is aligned with strategical ability. It resembles a dual-chakram connected to a hilt with exquisite gold markings by two long chains. The main blade is oval-shaped while the secondary is that of a circular blade with an accompanying crescent blade.
Shikai Special Ability:
  • Ryū Tenzoshu (竜天蒼瞬): Naoto's speed increases for a short time, allowing her to maneuver more quickly and deliver attacks at a much quicker rate; or simply to bolster her shunpo prowess and dodging ability. The technique is usable only by the Speed form of Ryūjōmaru.
  • Rengoku (煉獄, Purgatory; lit. "smelting/forging prison"): Naoto swings her zanpakutō forward, causing four geysers of flame to erupt from the ground. She can also release this attack at close-range from the blade, where she then slams it into the area around her opponent as blue flames. This causes the four geysers to join into a single geyser, which then erupts beneath the targets feet in addition to the initial flames. The technique is usable only by the Power form of Ryūjōmaru.
  • Rasen (螺旋, Spiral; lit. "spiral-shell (as of a mollusk swirl"): Naoto raises her zanpakutō into the air. Violet energy surrounds her and engulfs anyone surrounding her in the process, whether it be friend or foe. The energy itself can also randomly burn, freeze, shock, or poison anyone caught within the vicinity; making it a reliable offensive that is difficult to defend against. The technique is usable only by the Technique form of Ryūjōmaru.

Notable Relationships



Giselle Nagareboshi:


Akira "Senshi" Nakamura: Like Naoto herself, Akira originally came from Japan. As such he could sympathize with her moving away from the country of her birth to a country she knew little about; and helped ease the transition of moving by offering guidance and support. He was her teacher for many of her subjects during her school career, and later became her landlord after she moved away from her parents home.

Behind the Scenes

  • Naoto shares her character likeness with another of the author's characters: Mariko Kori. This is due to Naoto Fuyumine (the character both are based on) is one of his favorite characters from Dogs: Bullets and Carnage.
  • Naoto's unofficial title is Mistress of Bitchslaps. She slaps her childhood friend, Thomas, at least once in every chapter.
