Shinjuku forest at night. In the sap taverns of insects and their neighborhoods, the honey dumplings that drive the body crazy have begun to flow. It seems that Club Swallowtail's "Yuko" is involved with the stag beetle gang leader "Suigyu", who has a crush on him.... Kiri, an informant behind the scenes, and Hitoshi, a silent insect slayer, are on the move. Behind Yuko's back is a bewitching queen bee, and a beautiful butterfly, Ageha, is chasing after her... Money and power, love and hatred turn one midsummer night into a nightmare. The stag beetle, rhinoceros beetle, and wasp families, as well as a group of goldfish, are all caught in the middle of the bloodshed. What will Hitoshi and the others see? Hitoshi's blade shines and roars in the dark night where not even the moonlight can reach!
