The Nihonmatsu Siblings And The Adventure Of Wooden Valley

in the “japanese-style fantasy battle” story, mechanical sparrows chase after the girl nerine on a moonlit night, but a boy and a girl save her. the boy is the older brother akahiko, who is sullen, stingy, and polite to a fault. the girl is the energetic younger sister yukio, who can manipulate snow. the pair are supernatural problem-solvers for hire, doing anything from intimidation to exorcisms as the nihonmatsu siblings.
