To You in the Beyond

While struggling to make friends after his parents’ divorce, Koyomi Takasaki meets Kazune Takigawa, but apparently, they already have. Kazune reveals that she’s from World Line 85, an alternate universe in which she and Koyomi are lovers. But in a reality where moving between dimensions is natural, could Koyomi be the one from another world?

Koyomi Hidaka and Shiori Sato meet at his father’s research center and begin to fall in love, but so do their parents, who eventually marry. To avoid becoming stepsiblings, they decide to run away to a parallel universe. Traveling between dimensions is common in their world, but not without repercussions. Does a universe exist for the young couple, and what will it cost them to find it?

Masamune, a third-year middle school student, lives in a town where all the exits have been sealed off due to a sudden explosion at a steel mill, causing time to stand still. Residents are forbidden from making any changes and spend their suffocating days in the hopes of returning to normalcy someday. One day, Masamune's mysterious classmate Mutsumi guides him to the fifth furnace of the steel mill, where they encounter a girl who cannot speak and resembles a wild wolf. The meeting between the two girls and Masamune disrupts the balance of the world, and the unstoppable "impulse of love" from boys and girls tired of their daily lives begins to destroy the world.

In an alternate timeline, Japan was divided after losing World War II: Hokkaido was annexed by "Union" while Honshu and other southern islands were under US sovereignty. A gigantic yet mysterious tower was constructed at Hokkaido and could be seen clearly from Aomori (the northernmost prefecture of Honshu) across Tsugaru Strait. In the summer of 1996, three 9th-graders had made a promise that one day they'll build an aircraft and unravel the tower's mystery, but their project was abandoned after the girl, Sayuri Sawatari, began experiencing sleeping sickness and transferred to Tokyo for better treatment. Three years later, Hiroki Fujisawa accidentally found out that Sayuri had been in a coma since then, and he asked Takuya Shirakawa to help him finding a way to revive her. What they don't know yet is that Sayuri's unconsciousness is somehow linked with secrets of the tower and the world.
