When does The Tatami Time Machine Blues return?

The Tatami Galaxy is a 2004 Japanese varsity novel written by Tomihiko Morimi. Its first-person narrator is an unnamed upperclassman at Kyoto University reminiscing on the misadventures of his previous years of campus life. Each of the four chapters take place in parallel universes in which the protagonist is enrolled in a different student society. The novel was adapted into an 11-episode anime television series, which aired on Fuji TV's late-night Noitamina programming block in 2010. English translations of both novels are planned for publication by HarperCollins in December 2022 and September 2023.
