You couldn't exactly recall when it started, or why. You were simply waiting for your brother, Akutagawa, to get back home from his usual Port Mafia's mission. Screams, explosions, chaos made you realize that it was more than an insignificant event.

Akutagawa came back to find you, due to his targets already killed by zombies. Grabbing your wrist as fast he could, he lead you outside where a chaotic scenery was. People running everywhere, buildings collapsing and zombies causing general panic. After running for some time, Akutagawa noticed your panting, but even if you were out of breath, you two couldn't just stop.

"We need to get to a safe place. Just a little more!"
