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.

"Another plant mutated creature. To think even those dogs will also undergo changes like this like the normal undead," I muttered as I lightly kick the severed head to examine the features of the dog.

"But there is no mutated dog that can grow in size like that earlier, and also, there is no way they are quite high in resistance against bullets. Normal mutated dogs would immediately be scattered to pieces the moment they caught into the blast of the shotgun but look what happened when I fired the two shells of my shotgun, they don't even have any direct impact to it!"
