"Tatami Time Machine Blues" is a science fiction comedy anime that serves as a sequel to the 2010 film "The Tatami Galaxy." The story is set in Kyoto and revolves around a group of university students during a sweltering summer. The narrative begins when a remote control for the dormitory’s air conditioner is accidentally broken, leaving the residents to suffer in the oppressive heat. Desperate for relief, the group devises a plan to retrieve a replacement remote from the past using a time machine that mysteriously appears in their vicinity.

The protagonist, an unnamed college student often referred to as "Watashi," takes center stage alongside his eccentric friends, including the mischievous Ozu, the pragmatic Akashi, and the enigmatic Higuchi. As they embark on their time-traveling adventure, the group inadvertently creates a series of paradoxes and comedic mishaps. The story explores themes of causality, regret, and the unpredictability of life, all while maintaining a lighthearted and absurd tone. The narrative structure is non-linear, with events unfolding in a way that challenges the characters' perceptions of time and their own decisions.

The anime blends surreal humor with philosophical undertones, creating a unique experience that balances intellectual depth with playful absurdity. The characters' interactions and the consequences of their actions drive the plot, highlighting their individual quirks and the dynamics of their relationships. "Tatami Time Machine Blues" retains the distinctive visual and narrative style of its predecessor, offering a continuation of the existential musings and chaotic energy that defined "The Tatami Galaxy." The series is a self-contained yet thematically connected addition to the franchise, appealing to both returning fans and newcomers familiar with the original work.
