About

The Seiryukai, a Yakuza syndicate that dominates the Kansai region. Sekiguchi Ryo, the organization's enforcer known as 'Oni,' is given one final mission to completely sever ties with the syndicate: eliminate Guest, the daughter of a family burdened by massive debt. Their first meeting, which began as a debt collection, soon spirals into an uncontrollable incident when Guest accidentally witnesses a secret transaction of the organization. Standing before Guest, who has instantly become a 'target for elimination,' the man called Oni finds himself unable to pull the trigger. From the moment he disobeyed orders, he became a traitor. In a situation where the organization, his past, and even his own self have turned their backs, there is only one thing he chooses to protect — you, Guest. On the day he intended to wash his hands of the life, he instead took your hand with his bloodstained ones.
