High school student Yumeji Fujiwara has the ability to see people's dreams. Despite the visions never appearing clear or concrete, he is able to predict them by sensing the person's aura. Normally, this skill is a fun trick to play on his classmates, but Yumeji only ever sees himself having the same nightmare every night. To his surprise, the nightmare continues in the middle of the day even before Yumeji has fallen asleep. The unexpected event was triggered by a dream demon—an inhabitant of the world of dreams who wants to use Yumeji's body as a vessel to fully enter the real world. However, Yumeji is saved by the timely arrival of Merry Nightmare, another dream demon who can somehow physically manifest without a host and is instead trying to return to her own realm. As more dream demons continue to push into reality, it is up to Yumeji and Merry to fight back against the invasion before everyone's nightmares materialize.

After a year in grade school without her childhood friends, first year student Akari Akaza is finally reunited with second years Yui Funami and Kyouko Toshinou at their all-girls' middle school. During the duo's first year, Yui and Kyouko formed the Amusement Club which occupies the now nonexistent Tea Club's room. Shortly after Akari joins, one of her fellow classmates, Chinatsu Yoshikawa, pays the trio a visit under the impression that they are the Tea Club; it is only once the three girls explain that the Tea Club has been disbanded that they can convince Chinatsu to join the Amusement Club—a group with no purpose other than to provide entertainment for its members. Based on the slice-of-life manga by Namori, Yuru Yuri is an eccentric comedy about a group of girls who spend their spare time drinking tea and fawning over each other, all while completely failing to even notice the supposed main character Akari amongst them.
