Koori Chikage (郡 千景 Koori Chikage) is one of the main characters of the light novel Nogi Wakaba is a Hero. She is a part of the first Hero team.
Koori Chikage is a tall, quiet girl, with long black hair semi-tied up into a bun on the left side of her head. She has deep brown eyes and pale skin. She wears a red overcoat on top of her school uniform, a red ribbon to her shirt, and dons long red stockings.Her Hero outfit is deep red, almost kimono-like short dress. Her sleeves open up and have white section on their ends, and she gains many red and white pieces of fabric over her body for decoration. Chikage has black stockings with a dark purple design at the top, and white heels. Her now-jet-black hair grows to a tremendous size, and her ribbon used for her bun transforms into a red spider lilly, hiding her bun from view. She has a black under-suit and white seams dotting her outfit. Chikage's eyes turn red and her gloves are fingerless, with a purple diamond on top.
When she uses her trump card, Shichinin Misaki, Chikage wears a long, shredded white cloak, with red designs all over. It splits into a five-petal shape. Her white folds and armor excess (save for her neck brace) disappear, leaving a golden-seamed red and black dress underneath.
Chikage was born to two loving parents, but her father's childish behavior and her mother's affair turned her childhood into a nightmare. Constantly bullied because of her parents, many children 'pranked' her by pushing her down the stairs and even tried cutting her hair forcefully, ending up scarring her ears as she flailed.
Chikage found relaxation in video games, allowing herself to forget about the world around her and instead focus of shooting and leveling up. She slowly turned into an empty husk, unsure of herself and believing she was not a person of worth. When the vertex attacked, she found her weapon, the death god's Scythe, but did not fight, so it came as a surprise to her that she was in fact, a hero.
Chikage had been pumping her heart full of loneliness for so long, she was stunned when Takashima Yuna, fellow hero and later friend, started talking to her like she was 'someone of worth'.
Chikage is a shy and lonely girl who is not good at interacting with other people. Like many introverts she enjoys playing video games, and is shown to particularly enjoy shooting games and hunting games akin to Monster Hunter. Her constant bullying and her unstable home life have caused her to become extremely mistrustful of other people, only truly opening up to Yuna. She has also developed a severe inferiority complex, leading to her tragic rivalry with Nogi Wakaba. Her fragile mental state has led to her becoming especially susceptible to the mind-corroding effects of the Trump Card, but despite that she is a good person at heart who only wishes for acceptance.
Chikage fights using Ohagari, a scythe imbued with divine power. It has a long red and gold scythe then is much larger then the average person, which can fold up for easy transportation. She fights using this, which can sweep and clear out Vertex in a second. Her scythe is stated to have once belonged to a farming god who went on a rage-filled conquest after his friend's death, even destroying his funeral hut in the process-- thus cursing the scythe to destroy even the dead.
Chikage also has the ability to use a Trump Card. Her Trump Card invokes the Shichinin Misaki, a collection of seven vengeful spirits which grants her a long white cloak and the ability to split into seven clones, which can regenerate after death. She cannot be killed unless all seven are destroyed at once.
Chikage's teammate and leader in battle. Chikage almost instantly becomes envious of both Wakaba's skill in battle and her charisma, and therefore develops a bitter one-sided rivalry trying to surpass her. The nadir comes when Wakaba's recklessness leads to Yuna becoming critically injured, leading to Chikage slapping her. Her and Wakaba patch things up after Wakaba makes a sincere apology, but a combination of the despair caused by the deaths of Tamako and Anzu, the anger she feels at the ungrateful criticism of the Heroes, and the psyche-corroding effects of the Trump Cards heavily affecting her already-fragile mind causes this jealousy to resurface much darker than before, eventually leading to her attempt to murder Wakaba in the Jukai. However, Wakaba continuing to defend her from Vertex after she was forcibly de-powered by the Shinju makes her realize that she always could have been the hero that Wakaba was. This leads her to take an attack aimed at Wakaba, sustaining a fatal injury as a result. With her dying breath Chikage tells Wakaba that while she had always hated her, she had also loved and admired her just as much, and she is comforted by Wakaba's presence in her final moments.
Chikage's teammate in battle. Yuna's friendly and warm nature is the only one that can make Chikage open up, and Chikage considers her as her only close friend. Yuna is the only person whom Chikage will show her hidden nerdy side to, and she is implied to have a crush on her. Chikage is very concerned about Yuna's welfare, visiting her often when she is hospitalized and becoming angry enough at Wakaba for indirectly causing Yuna's injury to slap her. In her delusional fugue caused by the Trump Card, her seeing Yuna and Wakaba talking without her (despite them actually discussing how to help Chikage), and perceiving it as Wakaba stealing Yuna from her, leads to her plot to murder Wakaba.
- Chikage's theme flower is the Lycoris Radiata, better known as the red Spider Lily. They are infamous symbols of death or neglect.
- Chikage's last name (郡) can be pronounced as either Koori by itself or 'Gunkaki' when written directly with the rest of her name (郡千景), hence her nickname 'Gun-chan'.
- Chikage's nickname is pronounced 'goon-chan'. Despite its spelling, Yuna's usage of 'gun' is of Japanese language and descent, not the American word for gun.
- Her in-game nickname is "C-shadow" (Cシャドウ). ("C" being "Chi" in her name being shortened, and "Shadow" is the meaning of "kage" in her name.)
