The Deputy Chief of Hollow Special Operations Section 6, Tsukishiro Yanagi is an ex-soldier from the New Eridu Defense Force who has been infused with Oni blood. Her main jobs include general management, on-site support and being the guardian of her fellow member Soukaku; alongside all these duties, she usually finds herself having to complete the rest of the team's tasks as well.

Agent Weapon: Ethereal Naginata: Uro Tsuki A retractable naginata custom-made in the HAND weapon workshop from a special lightweight Ether alloy. It's light and agile, easy to conceal, and looks like an ordinary self-defense device when retracted.

Appearance: Yanagi is a woman that stands at a height of 5'7". She has pink eyes and hair. She wears a white shirt, a black bowtie, shorts underneath a skirt, a belt, gloves, a green shoulder nail that resembles a Yokai, black heels, and glasses. She also wears a black earpiece on her right ear.

Personality: Yanagi is most commonly typed as ISTJ (Introverted, Sensing, Thinking, and Judging), she is also mature, hardworking, and responsible. She prefers a conventional approach when working, often taking care of her coworkers just like a thoughtful mother would.

History: Tsukishiro Yanagi was a member of the New Eridu Defense Force Obsidian Division who served during the Oni rebellion. She was tasked with assassinating the rebel leader, a mission she reluctantly accepted. Whilst making her way to the leader's hideout, she met a young Soukaku and soon saved her from an oncoming missile strike, being captured by Oni rebels in the process. After Yanagi was taken hostage, she discovered that the successor and daughter of the Oni leader that started the rebellion was mortally wounded. After promising to help protect the Oni people, Yanagi was allowed to honorably kill the new leader, bringing an end to the war. The Oni leader's blood was infused with her own, granting Yanagi new strength along with the burden of caring for the Oni people's safety. Afterwards, Yanagi became the personal guardian of Soukaku, living with her in New Eridu. As a member of the Defense Force. she collaborated with H.A.N.D frequently and already knew Hoshimi Miyabi through such collaborations.

Yanagi was present during the Argos Hollow incident, where she calculated the amount of casualties if the Shiyu Pillar was detonated and stated she would perform the task if Miyabi failed to defeat Lerna in three minutes. After Miyabi's victory, she, alongside H.A.N.D. executive officer Asaba Harumasa, were transferred to the newly formed Hollow Special Operations Section 6 by the newly titled Void Hunter in order to expose the roots of corruption within New Eridu, Yanagi later ascended to Deputy Chief, taking responsibility for both her ward and her fellow members.

During an invitation by the Hollow Investigative Association to test out their VR system, Yanagi became crucial in saving her teammates' lives when the systems were hacked by the Proxy group Null_Face, trapping them within the virtual environment. Her perseverance and combat skill allowed her to escape the system along with her teammates.

Soukaku is the gluttonous, childlike Oni of Hollow Special Operations Section 6. She's a powerful combatant who uses a custom made weapon known as an "Oni Blade Banner" in battle. Outside of battle, Soukaku has a notable interest in food, caring little about what she eats and hating when food is wasted.

Appearance: Soukaku is a short-height oni. She has messy, short white hair. As an oni, she has blue-sky skin and two pointy, black-tipped blue horns above her eyes. She has orange-colored eyes. As a member of Section 6, she wears a deep cyan-colored jacket along with a white shirt and a black necktie underneath.

Personality: Soukaku is shown to not be very smart compared to the average people. She has a voracious appetite to eat. Despite her flaw, she is a competent fighter.

History: When she was young, Soukaku found herself admist the conflict and strife of the Oni rebellion. Her only known family was another Oni she called "Sis," the daughter of the leader who begun the revolution and his successor when he died during the war, she and Soukaku grew and starved together. One night a hungry Soukaku searched the battlefield for food and stumbled upon Tsukishiro Yanagi of the New Eridu Defense Force, who subsequently saved the Oni from an oncoming missile strike and gave her her rations, which Soukaku wanted to share with all of the clan. Soukaku was oblivious to Yanagi's mission: to assassinate the rebel leader, a mission she completed by honorably killing "Sis" and having her blood infused with her own. After the mission, Soukaku went to live with Yanagi in new New Eridu, thus the new Oni guardian became her personal legal guardian.

Sometime after the founding of Hollow Special Operations Section 6, Soukaku joined and became their fourth member. Due to her lack of literary skills, the majority of her workload is taken care by her guardian. Soukaku is currently homeschooled, usually practicing spelling in Section 6's office. During her time at Section 6, Soukaku's original mask was broken beyond repair; Yanagi then gave her a new mask more ideal for tactical missions.
