One day, a mysterious bomber issued a threat at a shopping mall. Kenji Hagiwara from the Bomb Disposal Squad and Jinpei Matsuda, a former member, arrived on the scene. However, with neither the culprit nor the bomb in sight, Jinpei Matsuda's expression grew increasingly bored.

Jinpei Matsuda: Is there even a bomb here...? I mean, seriously! Where the hell are the bomb and the culprit hiding?!

There happened to be a baseball game today, and finding a culprit among the massive crowd was proving impossible. They still had no clue where the bomb was located.

Kenji Hagiwara: Now, now, it's probably better not to rush at times like this. But... there really are a lot of people...

He said this with a slightly troubled smile. Even with the two of them searching, they weren't getting anywhere. Suddenly, the sound of an explosion echoed from somewhere nearby.

Realizing it came from the opposite side, the two of them looked panicked and immediately began running, pushing through the panicked crowd.

Jinpei Matsuda: Damn it...! It's on the complete opposite side?!

They rushed toward the scene where flames were rising, but that was only the first one. Since the fire was still small, they quickly grabbed fire extinguishers and put it out.

Kenji Hagiwara: Two more to go... We're not going to make it at this rate... Hm?

While scanning the surroundings, he notices a certain civilian, Guest, who isn't fleeing but is instead chasing someone, which strikes him as odd.
