Due to her father's influence, Toko constantly laughs, even when she cries in sadness, and likes to make jokes when she is happy, especially about her name. She is a very friendly little girl who is grateful, as shown when she thanked Sanji for feeding her soba noodles. She usually takes her job seriously, but was willing to be late to her courtesan's procession to try the soba.
Her cheerful and fun-loving nature also led her to disregard danger as she laughed uncontrollably at Orochi during his banquet despite the consequences. She also continued to laugh nonstop even when Orochi held her at sword point, threatening to kill her.
Toko is very close with her father, even though he sold her off. She would send most of her earnings to Tonoyasu to help support the citizens of Ebisu Town. When news about his capture and planned execution reach her, she ran to the Flower Capital, despite being targeted by the shogun. Toko cried hysterically after her father was shot to death.
While Hiyori was the oiran Komurasaki, Toko served as her kamuro. Hiyori is very affectionate with her, as she was worried when the latter went off to try Sanji's famous soba without informing her. She tried to defend Toko from Orochi when the shogun tried to kill her for laughing at him, which led to Komurasaki getting "killed" by Kyoshiro. Hiyori tried to protect Toko again when Orochi sent an assassin after her and fled the Flower Capital with her. Toko also knew the truth about Hiyori and her lineage as she said this is their secret. Her cheerful and bright personality helped Hiyori to push forward. When Toko received news of her father's impending execution, Hiyori immediately ran after the frantic girl out of concern for her safety.
Due to Zoro having saved her and Hiyori's lives from Kamazou, Toko is very grateful to Zoro for his actions and helped treat his wounds after his fight. She was also shocked to see him not laugh at her jokes. Despite this, Zoro also cares for Toko, as after she ran off trying to save her father, Zoro went after her along with Hiyori to save her.
During the shogun's banquet, Toko incurred his wrath by laughing at him and he mercilessly tried to kill her despite Komurasaki's pleas over her being a child. After Kyoshiro "killed" Komurasaki for her defiance, Orochi blamed Toko for the incident and continued trying to kill her. After Toko was able to escape, Orochi refused to let her live and hired Kamazo to hunt and kill her.
At some point, her father sold her to the Flower Capital. She became a kamuro for the courtesan Komurasaki and she sent the money she earned to her father back at Ebisu Town.
Wano Country ArcEdit
Toko went to a soba stand in the Flower Capital operated by Sanji, but after receiving her soba, the bowl was knocked out of her hands by some thugs from the Kyoshiro Family who were attempting to intimidate Sanji. Toko ran into a nearby alley and came out after Sanji and Franky had beaten the thugs, and to her delight, Sanji gave her another bowl of soba. After finishing the soba, Toko ran off to join Komurasaki in her procession through the Flower Capital.
Toko and Komurasaki went to Orochi Castle to partake in the shogun Orochi's banquet. When Orochi started talking about the return of Kozuki Oden's Nine Red Scabbards, Toko overheard the other guests making fun of him and was unable to stop herself from laughing. Orochi then attacked her with his sword, and when Komurasaki stepped in to defend her, Toko was carried away by the geisha Nico Robin, whom she had met at the soba stand.
As Orochi was going beserk in the banquet hall, Toko begged Robin to help Komurasaki, but Robin was more preoccupied with protecting Toko. Upon seeing Brook's spirit form, Toko screamed in terror and fainted. After Kyoshiro struck down Komurasaki, Orochi pursued Toko and Robin until Nami unleashed Zeus's lightning on him.
After escaping the palace, Robin and her group dropped Toko off in the red light district. After Orochi hired Kamazo to kill Toko, the girl and Hiyori fled and were later chased to the Ringo region. As they were fleeing from the assassin, they came across a confrontation between Zoro and Gyukimaru at Oihagi Bridge. Zoro then clashed with Kamazo to protect Toko and the woman.
After Zoro defeated Kamazo and fell unconscious from the wound he received from the assassin, Toko and Hiyori took him to a house in the Northern Graveyards, where Hiyori treated his injury. Toko then sat close to them as Hiyori revealed her relationship with Momonosuke and her past to Zoro. When Zoro decided to take a nap, Toko went to sleep along with him.
Brook later came to the house and told them about Komurasaki's funeral as well as Tonoyasu's capture and impending execution. Hearing about her father's plight, Toko quickly rushed to the Flower Capital to save him, with Hiyori, Zoro, and Brook running after her. The group later arrived at the Rasetsu District just in time to witness the execution. Seeing her father shot to death caused Toko great grief and sadness.
- In her debut, Toko made a joke about putting the O- prefix before her name as is common for females in Wano, saying she was not a boy. Otoko (男?) is the Japanese word for man or male.
- A kamuro was a courtesan-in-training. They were apprenticed to an established courtesan to learn proper etiquette and to become versed in a variety of feminine arts that would serve them later on when they had to entertain customers. They also assisted the courtesan while she was on a job by running errands for her.
