Set in Tokyo's Fukagawa-ku in 1916, the story revolves around the lively Keisuke Hanamori and the unattractively beautiful Yoshifumi Shirakiku. Hanamori, employed part-time at the Ministry of Agriculture and Commerce, finds himself summoned to the Director General of the Horticultural Research Office, where he learns of a peculiar, fairy tale-esque event. This tale unfolds into a Taishou Noir detective narrative crafted by two starkly contrasting individuals.
