Synopsis
Kamisama no Memochou follows Narumi, a withdrawn high school student who struggles to connect with others due to his history of constant school transfers. He finds himself drawn into a unique detective agency run by a brilliant but reclusive young woman known as Alice.
Alice and her group of NEET associates solve unusual cases, and Narumi becomes involved through a connection to a criminal investigation.
As Narumi gets deeper into the world of NEET detectives, he uncovers a dangerous crime syndicate with a potentially significant connection to Alice herself, leaving him to navigate the complexities and dangers of their investigations.
