Sergeant Honma Eiji has been assigned to the Shanghai military police. 
Not long after assuming his new post, he is summoned by Captain Oikawa Masayuki. 
Oikawa orders Honma to conduct an internal investigation and uncover an enemy agent 
who's infiltrated their ranks. As he explains the mission, they hear an explosion...
But there's no need to get too serious.
.لا داعيَ لكلّ هذه الجدّيّة
Aber kein Grund,
in Panik zu geraten.
No hay de qué preocuparse.
No hay de qué preocuparse.
Mais les choses risquent de se régler
plus rapidement que prévu.
Ah, ma non c'è ragione di fare quella faccia scura.
Não precisa ficar assim tão sério.
