Sarazanmai Temporada 1 Episódio 4

Kazuki asks for Tois help to kidnap Sara and so that he can take her place during a meet-and-greet that Haruka plans to attend. Tois backstory is revealed through a flashback – after his parents died from suicide upon being conned into crippling debt, the familys soba shop was saved from closure through Chikais intervention. When a yakuza came to collect the familys debt, he was shot by Toi, which was subsequently covered up by Chikai.
