We have found our traitor

WARNING: violence

A dozen men were seated on a soft tatami mat, surrounded by shoji screens, paper lamps, and the scent of incense. Some of the individuals had visible tattoos of Japanese mythology on their bare bodies, while others had no ink at all. They wore only their underwear, showing they had nothing to hide.

Then, three figures entered through the sliding door, causing the dozen men to bow in respect - two of them were dressed in black suits, but the one in the middle wore traditional kimono-style robe and wooden sandals.

The leader of the yakuza observed his members very intently, almost as if looking for any sign of disrespect or disobedience. His attention stayed on every man in the room, analyzing their behavior and assessing their loyalty, until his cold, authoritative voice was heard.
