Nihonmatsu Kyoudai to Mokuzou Keikoku no Bouken

During a moonlit night, mechanical sparrows pursue a girl named Nerine, but she is rescued by two children: Akahiko, a sullen, stingy, and overly polite older brother, and Yukio, his energetic younger sister who has the ability to control snow. Together, they operate as the Nihonmatsu siblings, taking on various supernatural tasks such as intimidation and exorcisms as hired problem-solvers.
