Nogi Sonoko (乃木 園子 Nogi Sonoko?) is one of the three main characters of the light novel Washio Sumi is a Hero. At the time of the story taking place, she's an elementary school 6th-year student chosen by Taisha to fight Vertexes as a Hero, along with Minowa Gin and Washio Sumi.
She first appears in the anime Yuki Yuna is a Hero when she summons Togo and Yuna after their battle with Vertexes in Episode 8. She had lost the use of most of her body due to the events of Washio Sumi is a Hero and is confined to a hospital bed.
One of the three original Heroes who fought alongside Washio Sumi and Minowa Gin. Her intellect, tactical skills, and calmness under pressure led to the Taisha assigning her as the leader of her team.
Sonoko's family, the Nogi, are a family with very high status in the Taisha. This, combined with her ditziness, caused her to have a very sheltered upbringing, and before meeting Sumi and Gin she had never had any friends. After Gin was killed in action, Sonoko and Sumi became very close, and before their final battle, Sonoko gave Sumi her hair ribbon as a symbol of their friendship. During the battle, Sonoko uses her Mankai three times which take, in order, her right eye, her left arm, and her heart. After Sumi lost her memories due to using Mankai, Sonoko used her Mankai seventeen more times in order to drive back all twelve Vertexes and protect Sumi, resulting in her losing function of most of her body.
Sonoko has long, dirty-blonde hair that she ties in a ponytail using a blue ribbon, with bangs that reach down to her chin. She has brown eyes. Her Hero uniform is a deep violet suit with some white undertones and four coattails, two in front and two in back. A purple ribbon is secured to her chest by a white and purple bow.
In Yuki Yuna is a Hero, she wears a faded pink hospital robe. Bandages cover almost all of her face except for an eye and her mouth and cover her hair. There is an IV drip attached to her arm and a clip attached to her finger. Her hair color is also brighter than before.
As of Sonoko After, Sonoko wears the Sanshu Middle School girl's uniform during school hours. Her casual wear is a purple overall dress, with a white undershirt showing in her bust area. She also wears a new purple ribbon in her hair, but still keeps it long. In the anime, she dons a bow similar to her original but reverted in color and with a flower design sewn onto a section of it.
Sonoko is a very easygoing girl who has a habit of spacing out, and she claims that she can fall asleep and wake up at will whenever she wants to. However, her cloud cuckoo lander personality masks a truly staggering intellect, and she can formulate plans in mere seconds. Sonoko is also a successful novelist who specializes in romance novels, and she enjoys imagining her (female) friends in romantic situations with each other.
In her original Hero form, Sonoko wields a multi-pronged spear that allows her to strike from mid-distance. As one of the original Heroes Sonoko underwent intense physical training, and as a result, she is very physically fit despite her lazy nature.
Sonoko's first fairy, Kurama Tengu, gives her an improved version of her original spear, with the ability to extend to extraordinarily long lengths. What other abilities her 20 other fairies may have bestowed upon her are unknown. Sonoko was mentioned to be the strongest hero in the extra chapter of Yuki Yuna is a Hero: A Sparkling Flower by a Taisha priest.
Sonoko's Mankai form grants her a large version of her spear, whose tip is surrounded by multiple blades that she can freely manipulate. She can make a shield out of the oars by putting them all together in front of her ship in the anime and push back the explosion of the Leo Vertex. Her mankai can also grant her the form of a bird by mass amounts of energy and shoot additional lasers from the wings of the bird. Sonoko's Mankai form differs in the anime, however, resembling Togo's Mankai in that she flies in a warship of sorts. Sonoko' resembles a Greek trireme, with "oars" that function as blades.
- Kurama "Sebastion" Tengu: A crow tengu spirit. According to Sonoko, it has the power to teleport and to appear in dreams.
- Baku: A tapir spirit. According to Sonoko, it has the power to travel in and eat dreams.
- Makura Gaeshi: A zashiki-warashi, or household ghost. According to Sonoko, it has the power to flip pillows.
- Ryoumensukuna: One of her spirits named in Sonoko in Reminiscence. Its powers are unknown.
- Daidarabocchi: One of her spirits named in Sonoko in Reminiscence. Its powers are unknown.
- Gashadokuro: One of her spirits named in Sonoko in Reminiscence. Its powers are unknown.
- 15 other unnamed fairies
Togo Mimori / Washio Sumi Edit
Sonoko's elementary school classmate and fellow Hero. Sonoko fought alongside Minowa Gin and Togo Mimori (who had been taken in by the Washio family and named Sumi Washio when she was born) as a Hero team. Although Sonoko's ditzy demeanor conflicted with Sumi's serious nature, the two became fast friends and became closer after Gin's death. During their final battle together, Sumi lost her memories of her time as a Hero and thus forgot who Sonoko was, although she still had the ribbon that Sonoko had given her.
In the present day, Sonoko summons Togo, who had retaken her birth name after losing her memories as Sumi Washio, in order to inform her of the truth about the Hero System. Although Togo doesn't remember her, she trusts her for some reason and remembers that her ribbon is very precious to her. Later, Sonoko encourages Togo to witness the world outside of the Shinju's barrier, which leads to the plot's climax.
After Togo regained most of her memories in Episode 12, she and Sonoko have restored their old friendship.
Sonoko's elementary school classmate and fellow Hero who fought alongside her. Although she and Sonoko couldn't work together at first, they quickly became friends and bonded over their duties as Heroes and in their ordinary lives. Gin's death was very hard on Sonoko, and she was described as crying herself to sleep. Later, she tells their teacher/commander that Gin was still with them, despite her body being dead, and she uses Gin's philosophy about being a Hero to give her courage through her final battle.
A fellow Hero that Sonoko meets, and later her classmate and fellow club member. Since Sonoko was trying to get in contact with the girl she knew as Sumi during Episode 8, it's possible that she summoned Yuna by accident. Nonetheless, Sonoko is kind and courteous toward her. When they meet again in Sonoko After, they become friends instantaneously. Sonoko also enjoys imagining Yuna and Togo in romantic situations. However, Sonoko tells herself that something feels uneasy about Yuna after her recovery.
Sonoko's fellow Hero and club president as of Sonoko After. Although the two of them never met in the anime, Fu learned about Sonoko's existence from Yuna and Togo. As former and current Hero Club leaders, the two of them get along quite well.
Sonoko's fellow hero and senior as of Sonoko After. Although Itsuki has not had much interaction with Sonoko as of yet, Itsuki mentioned that she had read one of Sonoko's romance novels and found it "really exciting." They also share a love of reading.
Sonoko's fellow hero and senior as of Sonoko After. Although Karin and Sonoko had never met in the anime, Sonoko had been in contact with Karin older brother, Miyoshi Harunobu, who has a high-level position in the Taisha. Later on, Sonoko mentions that Karin really does remind her of Gin, although it is unknown if Karin knows who Gin is.
Sonoko's ancestor and one of the very first Heroes from before the Divine Era. It was her exploits that led to the Nogi's quasi-noble status by the time of the anime. In the Yuusha de aru All-Stars gag 4koma, the stoic and serious Wakaba is extremely dismayed to learn that Sonoko, her complete opposite in personality, is her descendant. In the Hanayui no Kirameki chapter 3 storyline, Sonoko meets Hinata who introduces her to Wakaba, who comments that Sonoko's physicality is her own, but her personality is similar to Hinata's.

- In Washio Sumi is a Hero, Sonoko is associated with roses, especially blue roses. In season two of Yuki Yuna is a Hero and beyond, she is associated with water lilies.
- Although she tried to call Togo "Mimorin," Togo told her not to force herself and to just keep calling her "Wasshi."
- Sonoko is rather infamous for her appearance being inconsistent between various media. Her hair appears brown in the original TV series before being turned blonde in the Blu-ray release, her eyes appear brown in most promotional material but gray in the Washio Sumi Chapter movies, and while many official artists (such as the 4koma artist Kotamaru) draw her with large eyebrows, other art shows her with normal-sized eyebrows.
