As the bombing of the Shinsengumi headquarters nears, Hijikata and Okita are still unable to find any means for escape. Only one key exists to unlock the shackles chaining each other. But if the key is used, it will set off a bomb to kill the other. The rule of the devil begins to stir distrust between the two. Though he commends them for not betraying one another, Jigzaw pressures them to make the final decision by displaying a certain item.
It hurts me to say this, but you're the only one left who can save the Shinsengumi.
Me duele decir esto, pero eres el único 
que puede salvar el Shinsengumi.
Me dói dizer isso, mas você é o único
 capaz de salvar o Shinsengumi.
