I think your story could use some help. Later, if you wish, I could try helping you with small areas, probably things like character description. It seems out of character for Dashie to wear booty shorts seeing as how tight short shorts are a pain to run in.

Edit: reading farther on I must say, your character descriptions do need some desperate work. Are you not aware of how some one who wears a lab coat around school is treated?

Edit: even if this story took place in Texas it would get you suspended at the drop of a hat to have a gun at school. Even a fake gun. Many things can be used to kill the poor man walking funny. You're outside. Discord is a joke- I mean jock. Mayhaps there is a baseball bat handy?

Ok... I'm helping with your story. I have a bit of a zombie arsenal myself ranging from swords, throwing knives, shotguns, ect...

Just a friendly advice... Use capital letters! It is not so hard to do. Use one after your period, and each time you start a new line.

Like this. Easy as that
