Kyosei

Labeled as a delinquent and bad influence, high school student Kyosei Ichinose choose to stay out of the people around him, indulge himself to his headphones, pick fights against other people and stay alone. 

He was later famous for being a dangerous fellow that even his fellow students and his teachers feared him.

One day, everything is normal until the world is now in turmoil after the appearance of a mysterious disease that turns humans into mindless cannibals, infecting humans all around the country in an alarming state.

After receiving a distressed message from his former friend, he reluctantly returned only to find the school overrun by the dead. Armed with his house keys, a revolver and a duffel bag containing a few items to aid the rescue, he returned to the school without knowing why he still need to rescue a former friend.

Outbreak Chronicles: Dead Pandemic

Kicking the door open in front of me, the people inside were surprised to see it open in that manner. The middle aged man who looked so muscular but shrewd looking appeared before me while two of his body guards immediately pull out their guns and aimed them at me. However, I already suspected that they will do that so before they can shoot, I throw two throwing knives to their direction, immediately killing them in the process.

"Oy, old man, its been a while isn't it?"

"F*ck... f*ck, f*ck why are you still alive!?" he frantically scratch his head with his face sweating all over.

"Ha? Who said I died? You? Don't label me dead yet as I am still alive and kicking."

"I don't care! Why are you here?! Didn't we already avoided you like a plague? I didn't even bother to contact you anymore after your warning! Why did you attack and ruin my plans?!"
