Rewrite’s story revolves around the protagonist Kotarou Tennouji, a male high school student living in Kazamatsuri, and the story begins on October 3, 2010 on the Moon. Kotarou, who is interested in the unidentified mysterious animals in the forest in and around Kazamatsuri, spends times with five girls in the occult research society at his school: Kotori Kanbe, Chihaya Ohtori, Sizuru Nakatsu, Lucia Konohana, and Akane Senri, who is also the club president. The club members spend fun, peaceful times together uncovering the supernatural mysteries of Kazamatsuri. During this time, Kotarou falls in love with each of them in separate plot lines determined by the choices the player makes. These plot lines represent various timelines in which the conflict between Gaia and Guardian occurs, although it is hinted that humanity is inevitably destroyed in every timeline.
After the five heroine’s routes are completed, the story shifts to a setting amid a ruined Kazamatsuri where Kotarou encounters Kagari in a world after re-evolution, still on the Moon. Kotarou at this point is a unified entity of all the Kotarous from all timelines where humanity was destroyed and he has memories of these events. The Moon’s Kagari is trying to research a way so the Earth and humanity are not destroyed, and Kotarou attempts to buy her time while fighting a hoard of familiars summoned by Sakura Kashima of Gaia whose resolve is to annihilate humanity by killing Kagari. Kotarou and the ent
ire cast rejoin together to protect Kagari, who manages to finish her plan to allow the Earth and humanity to coexist by sending the Moon’s life force back to Earth. In the past, the Earth had sent this energy to the Moon so life could continue. There is just enough energy and resources left for a final re-evolution.
Prior to the initial events of Rewrite, Kotarou had been a low-ranking member of Guardian posted in Kazamatsuri, where he encounters Kagari. In one timeline, Kotarou is badly injured by Kagari, though he is healed into a half-familiar existence by a young Kotori with a piece of Kagari’s ribbon. Kotarou’s aging is also slowed as a consequence. Kotarou falls into a coma, and he is administered an amnesiac drug to forget about Gaia and Guardian. By the time he wakes up, Kotori is in junior high school, and Kotarou later graduates junior high with Kotori. He goes on to spend time in high school with the occult research society as shown before. In a different timeline when he encounters Kagari, Kotarou lets her go.
Kotarou becomes disillusioned with Guardian’s tactics and returns to Kazamatsuri where he meets Kagari again. She tells him she must initiate re-evolution, but since this would lead to a dead world, Kagari must find good memories brought out through the betterment of life on Earth, as opposed to bad memories caused by war and conflict. Kotarou agrees to help her and he acts as a double agent, demolishing Gaia’s and Guardian’s infrastructure in Kazamatsuri and killing those on either side. Kazamatsuri is partly destroyed when Gaia attempts to force Kagari to initiate re-evolution, but Kotarou manages to stop this from occurring. As a result, Kagari praises Kotarou and shows gratitude for showing her satisfactory memories. Kotarou unwillingly stabs Kagari, and after a kiss, they evolve into an orb of light inside a tree.
Humanity survives in the aftermath, but the world experiences an ice age outside of Kazamatsuri. In the city, a huge tree grows 500 meters tall in three years, which contains the orb of light from Kotarou and Kagari. The five heroines, now in high school, investigate the tree as members of the occult research society and transform Kotarou into a familiar, but he refuses to do what they demand. Kotarou takes the girls to the Moon where they are shown circled around a seedling (as the embodiment of the Moon’s Kagari) sprouting on the otherwise barren regolith.
