俺

A sleep-deprived hitman grapples with chronic insomnia. Operating under the pseudonym "Muraki Takeo" in Japan and the Hong Kong alias "Zeng Heixing," he has established a residence in a love hotel on the fringes of Kabukicho. His days are typically spent working at the hotel with little enthusiasm, only accepting assassination contracts when they arise. His life takes an unexpected turn after an encounter with Azami. Their sexual interaction leads to the most restful sleep he's ever experienced, leaving him reluctant to part ways with her.
