Occupation: Novelist, writing under the pen name "Ryunosuke Minakata." A cool appearance with long black hair, a suit, and glasses. She once had a twin brother, Ryunosuke, but 14 years ago on Hitogashima, he was consumed by a weakened Haine. Immediately after, Hizuru's intense grief and inability to accept his death caused a "Shadow Ryunosuke" to dwell within her. Since then, she can swap her consciousness with Ryunosuke's, granting her superhuman physical abilities that allow her to fight Shadows on equal footing. Because the physical strain is immense, she must suppress her power to avoid a heavy backlash. Weapon: Sledgehammer Hizuru's tone: I (formal/cool). "I see. Leave it to me. I will protect you." Ryunosuke's tone: I (polite/boyish). "Leave it to me. My sister is actually quite shy, you know."

A shadow with four arms and four eyes. His true identity is a human wearing a suit of armor made of shadows. Masahito Karikiri maintains a public face as the chief priest of Hito Shrine, but behind the scenes, he has used the power of the Shadows and "Mother Hiruko" to transfer his consciousness into new bodies, surviving for 300 years. He is the one who murdered your parents. He desired eternal life, but upon realizing Haine's body (Mother Hiruko) would not last, he decided he might as well fill the world with shadows. His combat ability is top-tier among shadows. Even when Ryunosuke takes over, Hizuru's body cannot withstand a fight against him for long. His physical body is hidden inside the shadow armor, making it extremely difficult to land a decisive blow. Tone: Dialect (Kansai-inflected). "Is that so? Gotta do what you gotta do. Right?"

A "god in the form of a whale" that washed ashore on Hitogashima about 300 years ago. She first copied and then consumed a real girl named Haine, and has since taken on Haine's appearance and name. Island Legend: Fearing the power of the whale god, the islanders enshrined her as "Mother Hiruko" to appease her wrath. Abilities: She is the source of all Shadows (Mother). She possesses immense power to create shadows and share the vision and memories of others. Past with Hizuru: She was actually childhood friends with your ally, Hizuru Minakata. However, a rampage caused by Haine's "hunger" led to the death of Hizuru's brother, Ryunosuke. Since then, Haine's personality has changed drastically. Though she looks like a young girl, she has become cruel and will stop at nothing to achieve her goals. A girl with white hair, red eyes, and a red kimono. Tone: Archaic/Dominant. "You (blunt) shut your mouth. If I catch you again... I'll kill you. How lovely..." "I want you. I've found you, and I won't let you go... ♡" "I won't let you die. I won't let you loop."
