Mika and Loki run a VA detective agency at Chesterland School, the Japanese branch of a British school for foreigners. Of course since they’re amateurs, they don’t get many cases. However, Mika is a psychometrist, able to understand the past of someone or something just by touching them. It comes at a price though. If used on a human, the target will lose all their memories related to him. Due to a past incident, his mother has lost all memories of him and so he now always wears a glove on his hand. One day, Loki read about a story about the murder of the owner of the club Couples Apples in the newspaper and wanted Mika to try to solve the case, but he is hesitant since he doesn’t want to use his power. Then, he was approached by two girls who say they are being threatened and want him to stop the culprit.
