I Thought My Regular Customer Was Just Chuunibyou

There was a regular customer at Poirot Café. Same time, same seat, same person. Amuro Tooru often heard her talking on the phone and typing away at her keyboard, but the things she talked about were a little strange. For example: All the cards turned transparent; a man had no money for food and hoped someone would give him five yuan; there were too many tanuki; the fox spirit's cooking was too salty today... and so on. Amuro Tooru didn't think any of that was a problem. What Japanese person doesn't have a bit of a chuunibyou streak? That is, until one day, he heard this regular customer talking about a mission involving the organization he had infiltrated... Amuro Tooru: “My regular customer, were all the things you talked about actually true?” Theme: A bystander keeps stumbling into one juicy secret after another
