Takamimi Shrine, which has a history of over 400 years since the Edo period, is situated in Tsukishima, Chuo-ku, Tokyo. The deity enshrined there is an elf who was summoned from another world and has become a complete recluse.

The elf deity, Elda, is served by Koito Koganei, the 15th generation shrine maiden of Takamimi Shrine. While being swept along by Elda, who enjoys modern civilization and geeky hobbies, she is thrilled by the Edo culture she learns about from her, and is warmed by the unbroken chain of connections between the people of Tsukishima and Elda. But this elf is still too lazy! What's more, an elf and shrine maiden duo from another shrine even appears...?

A laid-back downtown comedy that connects Edo and the new era of Reiwa is about to begin.
