Hitotose, Hirune

"The relationship between detective and assistant is not unlike romance!" Because of his natural tendency to assist others (a "helper type" personality that makes him constantly want to lend a hand), Tasuku Mitomo has always lived in the shadows. To get out of this rut, he has made it his utmost priority to "become number one." However, at the high school he transfers to, he encounters three detective girls, who turn out to be his rivals from elementary school with whom he had formed a detective club! Thus begins Tasuku's fierce battle to support the top detectives! However... these girls seem to harbor passionate feelings of a different kind...!?

Onsen, Nakaya

Spontaneous fires with no cause. A mummy found in a quiet neighborhood. Sunflowers blooming in the dead of winter. Beneath each reported paranormal event, a criminal presence may be hiding in plain sight. Anan, a cat-eared demi-human cop buried in everyday cases, finds herself reluctantly partnered with Kanai—a federal agent with spiked hair, dark shades, and secrets of his own. Together, they dig into a string of bizarre cases that defy logic. What lies behind the impossible may not be ghosts, but something far more dangerous. A mismatched duo. A trail of unnatural crimes. And a truth twisted by powers beyond reason.
