Plot

The Day of Revolution revolves around Kei Yoshikawa, a boy in high school who one day is informed that he is genetically female. This shocking realization causes his family to grow closer together and Kei decides that he is going to restart his life as a girl named Megumi. Megumi takes a six-month leave from school and returns as a first-year student with Makoto Yutaka, the niece of the doctor who aided in Kei's transition; Makoto also helps Megumi adjust to living life as a girl. Megumi is quickly found out by her old male friends who all start hitting on her once they discover the truth that she was Kei. Shocked at their new behavior, Megumi is appalled at the thought of ever dating any one of them or even getting a boyfriend. After a traumatic experience with a former enemy, she tells her friends that she has chosen Makoto instead of any of them, though they do not back down in their pursuits.

The Day of Revolution

Megumi, in an attempt to avoid her persistent male friends, starts spending more time at Makoto's house where she meets her younger brother Mikoto, who is home during the summer from an all-boys boarding school. Megumi starts to become more fond of Mikoto, though still only thinks of him as a younger brother, while at the same time Mikoto harbors feelings for Megumi. Megumi and Mikoto go on a date together but are interrupted by Megumi's male friends and Makoto. Megumi attempts to protect Mikoto from her friends' teasing of him, and in the process causes Mikoto to confess his love to her. Megumi and Mikoto begin dating though are still constantly interrupted and are thus unable to progress their relationship very far even two years later. However, they resolve to make progress together.

Characters

The main character, Kei was a rebellious boy in high school who would get into fights along with his three close friends. However, one day his doctor tells him and his parents that while Kei may appear to be physically male, he is in fact genetically female. He thus starts to live as a girl and even changes his name to Megumi, which uses the same kanji as 'Kei'. After the change in lifestyle, Megumi still has a problem with the transition from male to female. Even as Megumi dresses as a girl, she still feels more like a boy, and feels more comfortable when around Makoto. As a guy, he was often told he was cute, causing him to physically retaliate and retains much of the same personality after his transition. Megumi tends to be very outspoken and even blunt sometimes. Megumi appears in the series Princess Princess, by the same author of The Day of Revolution, as Mikoto's girlfriend, though only references are made about her past life in the manga and nothing in the anime. In the manga, Megumi once fears that Mikoto had something with the other Princesses and that the only reason he is interested in her is because of her past life.

The Day of Revolution

Makoto is Megumi's best female friend who acts as a kind of coach to guide her through the process of becoming a typical girl. She teaches Megumi things such as feminine mannerisms, and speech patterns that only Japanese girls use. She was given this task because she is the niece to Kei's doctor and because she wants to become a counselor after high school. Makoto is very protective of Megumi, not wanting anything bad to happen to her. She has a very strong personality and uses it to command people around her however she likes. Makoto often uses this trait to coerce her younger brother, Mikoto, into doing things she wants him to do, whether they be for her own benefit or his own. Like Megumi, Makoto also appears in the series Princess Princess as a minor character; she is still portrayed as Mikoto's sister. In the Princess Princess manga, once Megumi tells Makoto about her insecurities regarding Mikoto's sexual orientation, Makoto tells Megumi not to let him know that. Megumi thinks it is because it would hurt his feelings, but Makoto says that she does not want him to know how much Megumi loves him because it would make him happier.
