Hasegawa has a life-or-death encounter with assassins, and the Shinsengumi and Mimawarigumi compete over solving a fictional case.
As cops, we have the duty to find the 
truth even if it's shrouded in darkness.
من واجبنا كرجال شرطة أن نجد الحقيقة 
.حتّى وإن كانت محاطة بالظّلام
Nuestro deber es encontrar la verdad,
por muy oscura que sea.
Como policiais, nosso dever é encontrar a verdade,
mesmo que envolta de escuridão.
