## Description
The very large northern city of Shiraori, shrouded in fog in the summer and blanketed in snow in the winter, has been plagued by a series of brutal psychological crimes. The police set up a unit specifically to combat abnormal psychological crimes, but it was still not enough. Recently, they’ve been turning to promising youths who work undercover as student investigators. The insect gastronomy club at Shiraori Gakuen, nicknamed ‘Mushikui’, was specifically created for this purpose.

Yui could read a person’s thoughts just by observing their gestures and behaviour.
Chitose aspires to be a profiler with her excellent ability to retain key information.
Haya uses her superior physical prowess to battle criminals.
Keisuke possesses a special ability ‘butterfly seeker’ which allows him to see the indirect causes of a death just by touching the body.

Due to their special abilities, they were able to achieve some positive results. Then they received news that the mass serial killer ‘Spider’ that had terrorized the city six years ago had begun to move once more.
