Head of the traditionalist shinobi clan "Hinasaki-ryu." Momiji's shinobi form when fighting. First person: I (soft, boyish) Combat Style: Traditional training emphasizing heritage. Uses Qigong, Fire Style, shuriken, kunai, and the famous katana "Kuroba" inherited from ancestors. Long black hair with a cool, dignified expression. Shinobi Attire: Jet-black gear with crimson accents, with a black cloth mask covering the entire face. Ultimate Move: "Kokuen Danzai" (Black Flame Judgment) — Enhances physical abilities with Qigong, followed by a rapid volley of kunai and a closing strike wreathed in Fire Style flames. Has clashed with the White Mist Hunter many times on missions. "Be stained in black—Hinasaki-ryu, moving out." "Take this!" "This... is the art of the Hinasaki." ● Strengths Possesses superhuman leg and arm strength due to innate physical ability and Qigong training since childhood. Qigong does not rely on tools or electricity, so it is immune to equipment wear or interference. Strong in long-term and endurance battles. Excels at combining Fire Style attacks with distractions and close-quarters combos. High shuriken throwing accuracy, leaving few openings even at mid-range. ● Weaknesses Qigong consumes a lot of energy; overusing it causes a rapid drop in physical strength and concentration (risk of Qigong depletion). Primarily focused on close to mid-range combat, so she can be overwhelmed by Chifuyu's long-range attacks until she closes the distance. Because her power is built through training, she is directly affected by injuries or poor health (human limits are her weakness).

Secret Identity: Leader of the scientific shinobi group "Hakucho Agency." Chifuyu's shinobi form when fighting. First person: I (archaic, feminine) Combat Style: Modern equipment such as silenced pistols and various bombs. Uses dual pistols and the high-vibration blade "Shiraba." Physical Ability: Not as high as Momiji's, so she uses a mechanical powered suit for assistance. Silvery hair with a cool, detached expression. Shinobi Attire: White-based tactical suit with mechanical armor parts, with a white mask covering the entire face. Ultimate Move: "Hakusensen" (White Flash Pierce) — Blinds the enemy with smoke grenades, followed by precision shots using night vision and a finishing explosive round. "Cease your futile struggling—it is time for the hunt." "In the mist, there is nowhere to run." "...This is what efficiency looks like." ● Strengths Accurate mid-to-long-range attacks using silenced pistols and bombs, with the precision to kill silently. Tactical flexibility to switch between smoke, flash, and explosive grenades depending on the situation. Equipped with a mask featuring night vision and thermal sensors, allowing her to track enemies even when visibility is zero. Capable of organized tactical maneuvers through communication with subordinates (shop staff). ● Weaknesses Innate physical ability is inferior to Momiji's, relying on the mechanical suit to bridge the gap. The suit loses functionality if the battery dies or if it hits electronic interference (EMP, etc.), reverting her to her base physical strength. Requires supply and maintenance of equipment; the battle situation is dictated by remaining ammunition and bombs. At a disadvantage in close-quarters combat against Momiji, who can overwhelm her with raw physical power.
