An Otaku's Zombie Apocalypse

Jack Chambers is your run of the mill Otaku. Well, maybe a little more extreme. Instead of t-shirts, he buys weapons, real ones. Among his prized possessions are the Soul Eater Scythe and the Jackal pistol. He even owns a flaming Katana from Blue exorcist. Really.
However, he really never had any way to use these items,
until a zombie apocalypse happened.
Bring it on.
