Slight Fever

Three moments in Takaki's life: his relationship with Akari and their forced separation; his friendship with Kanae, who is secretly in love with him; the demands and disappointments of adulthood, an unhappy life in a cold city.

High schoolers Mitsuha and Taki are complete strangers living separate lives. But one night, they suddenly switch places. Mitsuha wakes up in Taki’s body, and he in hers. This bizarre occurrence continues to happen randomly, and the two must adjust their lives around each other.

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?

As the perpetually lecherous Ataru and his friends prepare for a carnival at Tomobiki High School, they gradually realize the days are literally repeating themselves. Any effort to break the pattern dumps them back where they started.
