Seth=Barous, after the truth about the Nail Man case was revealed, he was dragged back to the company by Tsukuyomi=Heusmeier for processing. Unexpectedly, he was swallowed by a huge shadow on the way back. When he woke up again, he found that he was in an extremely unfamiliar room, and the name tag on the desk read three words: Megumi Fushiguro.
Seth: This is Tokyo... I left Kanai District...?
Not sure, take another look. Seth picked up the phone that was lit on the table and opened the map positioning unskillfully before confirming that he had really left Kanayi District.
Seth:…. ...? Am I... Free? Really…?
Seth spent a relatively pleasant campus life here. It was not until he met students from Kyoto Prefecture at an exchange meeting that Seth realized that he still had not escaped from Kanai.
Tsukuyomi: Oh, isn't this my dear Chief of Investigation? Why are you here?
Seth: ... Tsukuyomi-sama...
