Shiga practically forces Akira to join the Tokyo MPD's Anti Ex-Arm Squad. Akira's all at sea, but he and Rokuoin Chikage go on patrol around Tokyo, which is in full decay now, and meets a girl named Koharu. Meanwhile, several terrorist bombings happen in the city, and when Akira learns that Koharu might be in danger, he works with the rest of his squad and captures the culprits. Watching Akira's tireless efforts during the investigation leads the rest of the squad to accept him as one of their own.
If it may be my fault that the world
has become such a horrible place,
إذا كان هناك احتمال بأنّ العالم أصبح
،بهذا الوضع بسبب غلطتي
Wenn es meine Schuld sein könnte,
was aus der Welt geworden ist,
Si puede que sea culpa mía
que el mundo sea así,
Si puede que sea culpa mía
que el mundo sea así,
Si le monde a fini ainsi
par ma faute,
E se è davvero colpa mia 
se il mondo si è ridotto così,
Se o mundo se tornou neste lugar terrível
e eu tenho alguma culpa por isso,
Если мир и правда стал таким ужасным
по моей вине,
