finn was running, his breath drew in large heaves as he ran through the woods, it was raining, he had to get to his treehouse, he had to, he just had to, if he didn't, he would surely die, he was looking behind him at the thing that was pursuing him, it's eyes gleamed in the light of the flashes of lightning through the holes in it's pointy hood, it's leather/chainmail armor shone as well, it's fingers, poking through the leather sleeves were as knives, it's four toed X shaped feet grasping every branch they came into contact with, finn rummaged in his pack and pulled out a jar full of blast powder, he lobbed it at the thing and it sliced it in half, the jar exploded and finn stopped, he looked into the cloud of dust, waiting, just then a knife sprouted from his shoulder, it wasn't dead, it was very much alive, angry, and still pursuing him, "damn, this thing means buisiness."
he turned tail again and ran, he could see the tree, "almost there, almost, almost."
just then, two figures flashed in his way, one was tall, it wore a fedora and a black trench coat, the other was draped in a black cloak, the hood over it's face. finn stopped and the larger figure, at least twice his size, towered over him, "well boy, what the fuck are you waiting for? get in the treehouse, we'll deal with the creature."
not sure weather to trust this strange figure or not, he ran up the steps and into the treehouse.
the creature came to a halt in the clearing, it saw the figures and took one more step before breaking into a run again, the larger figure pulled a katana out of it's trench coat while the other one fell back , he sliced at the thing's face, it dodged and appeared behind him, it then proceeded to slice with it's knives, attempting to cut it's opponent, but the figure sliced all it's knives in half, then impaled him with the sword, the other figure drew close to the taller one.
finn looked on in amazement, but then the figures began ascending the steps and he got scared, he ran further into the treehouse, got his father's sword and waited in the kitchen for the figures to walk in, and walk in they did, as they did so the larger one hung up his coat, revealing a t-shirt that said "i do all my own stunts" and a pair of jeans tucked inside muddy combat boots, he sported the sheath of his katana on his right, the shorter one flipped her hood back to reveal two bunny ears and a strand of golden hair, a blue t-shirt and skirt.
the big one removed his hat and revealed short blonde hair, he turned to face finn along with the girl, "hi there son, i'm home."
