Yomi (読) in her first name means reading in Japanese, while -ko (子) (literally 'child') is a common suffix in Japanese female names, so her first name means Reading-woman. This has the same meaning as her surname Readman if neglecting gender differences. The name is also shared by book publisher Yomiko Classics.

Through much of the R.O.D series, Yomiko works as a secret field agent for the British Library, using her papermastery to thwart the British Library's foes and collect valuable books and documents. Yomiko's code name is "The Paper" (while this is said in English even in Japanese dialogue, English dubs often turn this into "Agent Paper" or "Miss Paper" to make dialogue more smooth).^[4][7][8] She is the 19th person to serve the Library in this capacity. Yomiko is assigned her missions by the British Library special operations commander, codenamed "Mr. Joker." She often works with partners, such as the American mercenary Drake Anderson, the clumsy but capable junior field agent Wendy Earhart, and the suave wall-phasing gunslinger girl, Nancy Makuhari. When not on missions for the British Library, Yomiko works as a substitute teacher,^[9][10][11] a job through which she meets her favorite author, Nenene Sumiregawa. She resides somewhere in Jinbōchō, a neighborhood of Chiyoda, Tokyo known for its large number of used bookstores. She occupies a small shack at the top of an apartment building called Yomiko Building (読子ビル, Yomiko Biru) (the building itself is used entirely to contain her book collection).

Read or Die edit

Yomiko was trained by Donnie Nakajima, who served as the British Library's 18th Agent Paper. Yomiko was deeply in love with Donnie. After he failed in one of his missions (burning a British noble's book collection in the novels; refusing to find the "Book of Truth" in the manga), Donnie was killed because of the failure, which was labeled as betrayal by Joker. He was then used as a card to trigger Yomiko's power of a paper master. Yomiko recalls that she killed Donnie in her memories in both manga and novel, and is greatly troubled by that. In the manga, the "Donnie" killed by Yomiko is actually another paper master in disguise, which followed Joker's order to help Yomiko in discovering her power, and he appeared in the story later to retell the true events. This part of the story is yet to be told in the novel's last volume, and Donnie's death by Yomiko's awakening power is the only known factor, why Yomiko killed him is unknown. She became the 19th Agent named The Paper after the incident.^[12]

Read or Die OVA edit

The OVA does not carry on from the books or manga and picks up with her still working loyally for the British Library, where she meets a new partner in espionage, Nancy Makuhari, aka "Miss Deep" (introduced as a new character, although she existed previously in the novels). Little history is provided on Yomiko in the OVA.^[2] She aims to recover rare manuscripts for the British Library as an agent for their Special Operations Division.^[13]

R.O.D the TV edit

At the beginning of R.O.D the TV, Yomiko is missing in action. Four years before the start of the series, she is provoked by Joker and ends up in a moment of temporary psychosis, assaulting the library with her papermastery and causing it to go down in flames.^[5][14] She is later revealed to be in hiding while protecting Miss Deep's clone, also called Nancy. She has abandoned and betrayed the British Library upon learning of Joker's plot to use the second Nancy's son as a vessel to be overtaken by the mind of Mr. Gentleman, the founder of the British Library.^[15]

Yomiko is a woman of English and Japanese descent (though Nenene describes her as looking "100% Japanese" in her "missing persons" ad^[16]). She is a light-skinned woman of average height with dark blue eyes long straight black hair. She is of slender built yet sports a noticeably curvaceous and well-endowed figure. In a series where most characters enjoy frequent changes of costume, Yomiko always wears her British Library uniform: red tie, white blouse, brown waistcoat, and brown skirt; she also usually wears a roomy buff overcoat. Even when she leaves the British Library in the TV, she still wears the same outfit, only swapping the necktie for a small red ribbon instead. Yomiko sports enormous, black, square-rimmed glasses; in the manga she reveals these were Donnie Nakajima's, and she refuses to remove them even when sleeping.

Yomiko is introverted and has bibliomania, often preferring the company of books over people.^[17][18] She goes to extreme lengths to hold onto and finish reading something she has started; for example, when attacked by a giant insect, she is more concerned that the insect's rider stole the book she was reading than by the insect itself. The only time she has actively rejected books was in the manga, too distraught in thinking about her past with Donnie. While a capable secret agent, Yomiko is extremely kind-hearted by nature and exceedingly polite. She is even said to be "meganekko".^[19]

Yomiko's telekinetic ability to manipulate paper into bulletproof shields, swords, working giant paper airplanes, models of Big Ben, etc. surpasses the abilities of most other paper masters in the R.O.D universe.^[20] The effects she can create are limited only by her imagination. She is able to slow the burning rate of paper dramatically, and can work with paper that is slightly wet (complete and utter saturation will still disrupt her paper mastery, but only in that moment). She can command very large volumes of paper and change their shape, speed, and direction easily. Yomiko can also manipulate paper with her mouth, as evidenced in the OVA when she manages to free her hands from a pair of metal cuffs with only a thin piece of paper braided into her hair. Although Yomiko's paper mastery is her most impressive ability, she also displays great agility (with the exception of the first novel, in which she is clumsy; she explains that this is because she hasn't read any action novels recently).^[21]

Donnie Nakajima edit

With the manga to go by, Yomiko was head-over-heels in love with Donnie and deeply traumatized by his death at her hands. She wears his glasses, with the idea that when she reads, he sees what she is reading. Yomiko can get violent if someone touches her glasses. Often when thinking of the past she touches her glasses self-consciously. In the TV, Joker implies Donnie's fate is even worse than Yomiko thought, sparking her temporary insanity during which she destroyed the British Library.

Nenene Sumiregawa edit

Yomiko loved Nenene Sumiregawa before ever meeting her, sharing the joy of reading the young author's novels with her mentor and romantic partner Donnie Nakajima. When Yomiko met Nenene she begged her for her autograph, but didn't earn it until she had rescued the author from a vicious kidnapper. The two quickly became fast friends, and Nenene even followed Yomiko on her assignments for the British Library. When Yomiko disappeared before the start of R.O.D the TV, Nenene was devastated, and Yomiko came to deeply regret abandoning her. Fortunately they were able to reforge their friendship.

Nancy Makuhari ("Miss Deep") edit

One of Yomiko's partners at the British Library, Nancy Makuhari, codename "Miss Deep" is a somewhat mischievous, sultry agent who quickly grows close to Yomiko as the two embark in a number of missions for the library as teammates.^[22] In the R.O.D OVA, Miss Deep befriends Yomiko quickly. The two share a strong bond through the series, to the point where romantic overtones are possibly implied. Nancy appears to betray Yomiko in the second episode—but that turns out to be Nancy's clone, loyal to the I-Jin Soujun Ikkyu.^[23] Miss Deep nearly dies rescuing Yomiko from Ikkyu's trap and betrays Ikkyu in the final episode so Yomiko can escape—but remains aboard a doomed rocket as Yomiko helplessly falls away from her with a parachute. An extremely distraught Yomiko finds in her hand Nancy's last request written on a crumpled bookmark that Yomiko had given her earlier as a keepsake: "Please take care of my younger sister."

Nancy the Clone edit

Seen only in the animated R.O.D adventures, Miss Deep's clone is originally Yomiko's enemy, capturing her on behalf of the enemy I-jin leader, Soujun Ikkyu. However, Miss Deep nearly kills her, and the clone loses much of her memory due to brain damage caused by asphyxiation. Yomiko, honoring Miss Deep's last request, vows to protect her. She fails, however, to protect Nancy's son after his birth, and only manages to escape with Nancy and go into hiding, telling Nancy that her son died. Through much of the TV, the recovering, childlike Nancy's world revolves entirely around Yomiko. Even when Yomiko reveals that Nancy's son lives and that she lied to her, Nancy easily forgives her (though Yomiko is much less forgiving of herself). Nancy matures by the end of the series but remains devoted to Yomiko.

Wendy Earhart edit

In all R.O.D stories except R.O.D the TV, Wendy is Yomiko's devoted friend and fellow agent. While Wendy is a less experienced agent, it is sometimes her job to keep Yomiko from getting distracted. She worries greatly when Yomiko is in danger, even when Joker—to whom Wendy is extremely loyal—is less concerned. In the TV, an older and very jaded Wendy is bitter about Yomiko's causing the British Library fire, feeling betrayed by the woman who was once her hero. She has little difficulty fighting on opposite sides from Yomiko—although when it comes down to the wire, Wendy still cannot shoot to kill.

Anita King edit

In the TV, young Anita is a victim of the British Library fire and recalls Yomiko's silhouette standing out amid the flames in her most traumatic memory. When Anita learns the truth of her memory, she is extremely harsh and unforgiving toward Yomiko, although Yomiko as always remains apologetic and gentle toward the teenage girl. When forced to work together to fight the British Library, Yomiko manages to teach Anita a few things about papermastery tactics and demonstrates Anita's further potential by showing her how to fly a giant paper airplane over the mountains of Saitama. Although the meeting is much less significant compared to their interactions in the television series, Yomiko makes a brief cameo appearance in the Read or Dream manga at the end where she coincidentally encounters Anita at the park and senses Anita's close connection to books despite Anita's denial and helps the girl realize how books have helped her find the friends and family she has.
