Arata naru Sekai: Mirai-hen

The story is set one autumn at the beginning of the 21st century in the Uchihama area. Uchihama Academy is growing by leaps and bounds. With the construction of a new school building, there will be one last General Club Festival at the old building that is slated to be closed. The students vow to go all out to make this final cultural festival a success. The Astronomy Club of the protagonist Sou Akiyama is filled with the big names on campus. Just before the festival on October 1, the club receives a request from the student executive committee to calm the uneasiness among the students. There are reports of ghost sightings, accidents, sleeping sickness, and other mysterious incidents at the old building. When Yui Furukawa, a quiet girl who transfered late into the school, appears before Sou, the gears of fate slowly begin to move.

It was just another ordinary afternoon for our heroine Suzuko when she suddenly got caught in a giant gas explosion. Instead of getting killed, Suzuko wakes up some 500 years in the past during the Civil War era of Japan. After being saved from a fate worse than death by a handsome, somewhat overbearing young man, Suzuko learns to adapt to the strange realm where she now resides. Along the way, Suzuko finds out more about her mysterious and spotty past. As clues begin to click into place, though, the village is attacked, and Suzuko finds herself travelling through time AGAIN, this time to the present. Will she solve the mystery regarding her origin and where she belongs?

In the distant future, a mysterious floating object appears suddenly in the center of the city. The top secret mission unit "Alta Mira Agency" or AA is comissioned by the Defense Agency to deal with this mysterious invader. In charge of the robot training is Hunagai Otsuya. He must choose one of the girls to recieve special training which she will recieve in secret. They must use the "Battle Soles" to push back the enemy even at the cost of their lives.

The "heartwarming" anime's story follows the two titular women Escha and Chron, whose contrasting personalities are like the sun and moon. The two women are from "Terminal," a future post-apocalyptic world that's empty and monochrome. The two women cross worlds and arrive in the present day, which they call "Transit." As Escha and Chron experience the light (scenery) and sound (music) of the real world, the future world of Terminal gradually changes into a more vivid world.
