In the present day, the world is in turmoil due to an "unprecedented disaster." A young man living in Tokyo, Suzushirō, has a secret he cannot tell anyone. That secret is that he can stop the time around him despite his thoughts. One day, he meets a girl named Nazuna who has the same "power". When he learns that she is being used in a crime, he impulsively reaches out to help her.
Love is love. Someday, the pain of being in love will be an endearing memory. No matter who the feelings are towards, no matter what form it takes, all love and lifestyles have the same value. An omnibus anime tells the stories of “The wedding of an ex”, “a student and a teacher at an all-boys’ school” and “childhood friends whose bodies and hearts change with adolescence.”
Twenty-six-year-old Hiroto Suwa; his wife, Naho; and their old high school classmates—Takako Chino, Azusa Murasaka, and Saku Hagita—visit Mt. Koubou to view the cherry blossoms together. While watching the setting sun, they reminisce about Kakeru Naruse, their friend who died 10 years ago. Mourning for him, they decide to visit Kakeru's old home, where they learn the secret of his death from his grandmother.
The battle is over, and they can go about their normal lives now... or so they thought. With no time to rejoice after miraculously saving Mirai from Beyond the Boundary, Mirai lost all her memories. Akihito, now a high school senior, starts to avoid Mirai thinking it’s for the better. Not aware of Akihito’s feelings, Mirai tries to get closer to Akihito. Then, someone who knows of Mirai appears in front of the two. With Akihito’s troubles in vain, Mirai once again sets forth on a battle that forces her to look within.
