Spiking the Undead [LONG HIATUS]

The world is a mess. Zombies - also known as Walkers, have overrun Karasuno High. Hinata Shouyou has no idea where his friends are, but he does know that these Walkers are dangerous and will kill any living human being.
He needs to reunite with his friends, but after being cornered by a lot of Walkers, he lost all hope. Will he keep moving on and become a badass, or will he just sit there and die?

[ AaaAaHhHh i don't know how to make a decent, non-cringey description. i'm so sorry, but i can't make one without lots of spoilers from the story. i'll make a better one once i finish this. ]
