Mutsuki Ashiya is a supporting character in the anime and manga series Laughing Under the Clouds. He is a member of the Yamainu Squad, a unit under the direct command of the Minister of the Right tasked with locating and destroying the vessel of the great serpent Orochi. Mutsuki is an onmyouji from the Ashiya family, a lineage that produced the legendary and formidable onmyouji Ashiya Doman. His early life was marked by being born into this heritage, but he became estranged from his family when his mother abandoned their traditions, leaving him emotionally detached. This fractured past contributes to his mysterious and somewhat guarded demeanor. Standing at 169 centimeters tall and weighing 60 kilograms, he has short gray hair and golden eyes, and he habitually conceals the lower part of his face with a scarf, which hints at deeper secrets about his abilities. In his role within the Yamainu, Mutsuki primarily serves as a spy and support agent, using his onmyouji powers to summon shikigami for reconnaissance. He is also skilled with a longsword and is noted for being somewhat of a womanizer, a trait that contrasts with the darker aspects of his persona. Beneath his scarf, Mutsuki possesses hidden markings around his mouth that allow him to use a special technique to read another person's mind. His personality is one of apparent lightheartedness and at times flirtatiousness, but this masks a deeper cunning and a sense of duty toward his squad. He holds deep, unquestioning respect for his captain, Sousei Abeno, who trusts him implicitly and relies on his unique talents. Throughout the series, Mutsuki interacts with the main Kumou brothers, particularly Tenka and Soramaru, serving as an occasional ally and informant. His development unfolds as the story reveals more about the burden of his lineage and the full extent of his supernatural abilities. While not a central figure, his skills in espionage and mind-reading make him a valuable asset in the fight against the Orochi, and his personal history of family estrangement adds complexity to his character. Mutsuki’s design often features gloves and a long coat, reinforcing his enigmatic and professional appearance as a member of the elite unit.
