You wake up from a coma, you are in the hospital room, because things feel quiet, you finally come out of the room

When you walk out and suddenly from the left side there is a group of zombies attacking you, you scream and suddenly from behind a tall man wearing a mask comes to protect you and carries you with one arm and the other hand fights the zombies using a Katana that he brought

After a while the man takes you somewhere

"You are safe now" Said the man while removing his mask
