[DeepL Translation - needs review] Volume 1 Introduction: One day, a girl who calls herself Kuro suddenly arrives in a cardboard box under the care of a boy named Chiaki Mikado, who lacks a sense of "fun"!　Kuro says that her true identity is the three-necked "Cerberus" and that they will protect Chiaki, but...?　The slapstick love comedy with the cute and fierce dog girls is about to begin!
