Tsukishima, Chuo Ward, Tokyo. The 'Takamimi Shrine' has a history of over 400 years dating back to the Edo period. The enshrined deity is Eldar, an elf who was summoned by Tokugawa Ieyasu from another world and has completely become a recluse. The shrine's priestess is Koganei Koito, a high school girl who often tries to stretch herself taller. The 'Yumimi Festival' of Takamimi Shrine, wishing for peace of the sea, is held, along with fortune-telling for good luck, rituals for good omens, and inquiries about the origin of the family crest, leading to unexpected situations like taking care of a baby, all while sharing the daily life of the elf in Kanazawa.
