[Onmyoji] This Unlucky Player Has an SSR Over Their Head

Ordinary high school student Toyama Kiya is transported back to ancient Japan overnight, becoming the orphaned heir of a declining onmyoji family and inexplicably shouldering the burden of restoring it. "Can I refuse?" "If you can't make it back in time, you'll have to sit at a table with Liang Feifan." Who knows how long later. The transformed boy finally summons his first SSR shikigami on a rainy night. "My father!" "I have no children." In this setting, an Ootengu stands 1.8 meters tall after folding his wings. Pairing: the tengu. [Note: The historical setting is slightly fictionalized] A couple solve mysteries and fight monsters at each stop along their journey.
