The Story of “Long Summer on August 31”
Suzuki and Takagi are two high school students who meet while August 31st repeats over and over again. They are the only two who can carry their memories forward from one loop to the next.
The likely cause of the time loop is the ultimate goal for every boy that Suzuki failed to accomplish during summer vacation. It is a coming-of-age time-loop comedy that tackles the topic of romance head-on.
The latest volume is Volume 13, released on August 21, 2026. After spending August 31 as a “family” with Manatsu-chan, the story unfolds as the two finally begin “living together.”
