"There was one person who stood up to the F4. That there was one girl who made enemies of the entire school. As for me, when our company went bankrupt and our things got repossessed, I put on a fake front as I continued to go to school. I cowardly protected myself. If the truth was ever discovered I planned to run away with my tail between my legs. I can't be like that girl."
—Oto Edogawa[src]

Oto Edogawa (江戸川 音 (えどがわ おと) Edogawa Oto) was a student at Eitoku Senior High and former fiancée of Tenma Hase. She was the daughter of Makoto Edogawa, the president of the bankrupt Edo Quality Cosmetics. Following the bankruptcy, Oto and her mother moved into an apartment in Tokyo, where she obtained a part-time job at a convenience store.


Early life

Oto was the only child of her mother and father. Her father was the president of Edo Quality Cosmetics.[2] His business was successful at the time. Oto later lived briefly in Paris with her parents.[3]

During her childhood, she became friends with Tenma Hase, who was the son of her mother's best friend. Their mothers wished for to "become family through [their] children." Oto and Tenma were subsequently engaged, sometime before or after his mother's death.[4]

Oto enrolled into Eitoku Academy during junior high.[5] By this time, her family's company was bankrupt. She and her mother lived in Tokyo,[2] while her father worked in Kyushu to pay off his debts.[6]

High school

Oto graduated from Eitoku Junior High and moved on to Eitoku Senior High. She later got a part-time job at a convenience store. Tenma's parents agreed that the couple would remained engaged, if Oto continued attending Eitoku. Oto spent much of her early days in high school hiding her financial status from the Correct 5, so she could stay at the school.[7][4]

Meeting Haruto

"Telling us to come to your house and then lording it over us. I don't care if you're the king of the school or whatever, but there's one thing I do a human being, you're the worst. Don't ever invite me to anything again!"

One day, she accidentally ran in front of the Correct 5's car. She was able to make up an excuse and left quickly. Later that day, the Correct 5's leader Haruto Kaguragi went to her work to retrieve his mail-order items. They recognized one another and she realized with horror that she would probably be kicked out of school. The following morning, Haruto confronted her and told her to get out. At that moment, they noticed another student being harassed. Oto went to help her and called Haruto "pathetic" for not trying. Haruto then punched the harasser as the others cheered. Oto used the moment to threaten to expose Haruto's affinity for mail-order items.[7]

Later at work, Oto agreed to go to a barbecue with her co-workers, when Haruto walked in and overheard. He invited them to hold it at his house. Oto only reluctantly went to his house with her co-workers. He talked condescendingly to them, which annoyed Oto. She then picked up a "hunk of beef" and slapped him with it.[8] Oto left his home, after calling him "the worst". She later apologized for the failed barbecue to her co-workers. On her way home, Oto's co-worker Maeno followed her into the park. He grabbed her arms when she tried to get away from him. Haruto came out of nowhere and kicked Maeno, who ran away from the scene.[2] He then accidentally admitted to following her, which she called "creepy". Oto later realized that the situation might have been worse if Haruto had not shown up. That night, she visited him at his mansion to thank him.[3]

Oto was later invited by her school friends, Kyoko and Asami, to go eat pancakes. She had to decline since she could afford it. Haruto overheard them and asked her out for pancakes the next Sunday. Oto agreed in order to repay him for saving her from Maeno. That Saturday, Oto went on a date with Tenma.[9] That Sunday, they met up near the pancake shop, which Haruto had bought to avoid lines. Haruto asked her about her reason for wanting to stay at Eitoku. He assumed it was because of the F4 and took her on a "pilgrimage" to their houses. At Tsukasa Domyoji's house, Oto admitted the real reason she wanted to stay was because she was betrothed to Tenma.[10] Haruto called her life "pathetic" and she replied that it had "nothing to do with [him]".[11]

Her secret revealed

"While I was struggling every day at Eitoku Academy, there were a few times when I felt like my old self. I had suppressed my true self. But without realizing it, it had come out again. Because of that weirdo. Haruto Kaguragi, ironically, it was when I was around him."
—Oto Edogawa[src]

A few days later, Haruto suddenly showed up at her job, asking "won't I do?"[12] She had no idea what he was talking about. Before she could ask what he meant, her coworker Konno interrupted them. Konno then invited Oto and Haruto to her apartment, when he began complaining about a stomachache. Oto reluctantly tagged along and cooked dinner for the three of them. Konno stepped for a moment, allowing Oto to ask him about his question. She guessed that he was "comparing [himself] to" Tsukasa Domyoji, not knowing he was actually thinking of Tenma. On their way home, Haruto apologized for his earlier insults. Oto forgave him with a smile. He then said, "don't say that your life has absolutely nothing to with me," leaving behind a confused Oto.[13]

Later at school, Oto discovered several fliers calling her a "peasant". The entire school began acting cold toward her, including her friends, Asami and Kyoko. Correct 5 member Airi Maya confronted her by telling her not to "go crying to [Haruto]". Oto asked her if Haruto posted the fliers, which Airi affirmed. At the school gate, she ran into Haruto and told him to "stay away" from her.[14] Oto decided to quit Eitoku and went home to tell her mother. However, she lost her nerve, after hearing her mother's wishes to see her and Tenma married. She put off telling her mother and went to inform Tenma. At his house, Oto told him that he was "free" now. When Tenma tried to blame the Correct 5, she placed all the blame on herself.[4]

In the morning, Oto went to school with the intent to quit. A student unexpectedly poured water on her and another punched her in the face, when she stepped inside the school. Oto was beaten badly by the time Tenma found her. He swiftly protected her from the others, before it was revealed that he paid a donation in her name. When Oto questioned him, he replied that he wanted to begin living for her "sake".[5] Tenma took her to the hospital and insisted that she stayed overnight. He indirectly confessed his feelings by saying, "I never once thought of you as just a fiancee arranged by my parents." After he left, Oto thought the exact opposite of what Tenma said.[15]

Physical appearance

Oto was a pretty, young girl, though not overly cute. Oto had medium length, brown hair, which framed her oval-shaped face. She had clear, round eyes, a small nose, and a pointed chin. Oto was of an average height, standing at 163 centimeters. Her wardrobe consisted of mostly casual, comfortable clothing, when she was not wearing her school uniform.

Personality and traits

Overall, Oto was a kind, caring, and hardworking person. After her family went bankrupt, Oto became responsible and practical with money. She was mostly uninterested in her former lavish lifestyle, unlike her mother who tended to dwell on the past. Prior to enrolling at Eitoku, Tenma said that Oto was "always laughing", that "[she] enjoyed life so much", she was talkative, and "said what [she] thought". In contrast, Oto later was usually quiet and constantly making up excuses to cover up her secret. After her secret was exposed, Oto was able to be herself more, but was still reserved.

She desired peace and wished for an easy, normal life. Oto's favorite word was "serenity", a synonym for calm. Her hobbies consisted of reading books, watching movies, and sleeping. She also dreamed of having a pet.


Oto ( () ) is an Old Japanese word that was originally derived from a Chinese character written the same way. Her name uses the kun'yomi pronunciation of the word; rendered in Hiragana as おと. The character can also be pronounced as on (おん () ), in (いん () ), or ne ( () ). Oto means "sound".[16][17]

The characters 江戸 (Edo) of Oto's last name is an old name for Tokyo. Individually, they mean "cove, inlet" and "entrance, gate, door".[18] The third part means "river". It can be pronounced as sen (せん () ) or kawa (かわ () ),[19] but is actually read as gawa (がわ () ) in Oto's name. Her last name is written as えどがわ in Hiragana.
