Catch a Tiger by the Tail

The boy followed the wounded Black Tiger into the other realm. The Black Tiger demon attempted to shift shape again but was badly injured. The living arm cut its way out of the Tiger bringing it to within a centimeter of death, at which point the boy in one crushing blow from the crystal brought downn on its nose, ended its wretched life. The crystal shattered into shards, one large enough to use as a knife. Others mixed with the blood of the Tiger Demon became alive and seeped into the ground or flew into the air or dissappeared into a nearby stream.
-The boy, unsure of the Tiger's death continued to cut into it, and its blood mixed with his as well. The boy gained strange knowledge and strength from this and realized too that the demon had been slain.
He sat back , breathless, and saw the fierce arm that held one of the swords that had been mounted on the Tiger fork. It made as if to cut the boy. The boy raised his crystal shard in defense and the arm did not approach, but hung there in the air. It then dissappeared into the woods.
After what seemed like a very long time, the boy collected his senses. He removed the skin of the Tiger Demon and wore it. The rest of the body seeped into the ground taking the Tiger fork, the other sword and the two daggers with it. It was now getting dark.
The boy then bathed himslef in the river, Tiger skin and all.
He emerged in the moonlight as a man, the Tiger skin appeared as a well made dark cloak over his clothes. The shard of crystal was a short single edged sword he wore at his side.
He had gained even more knowledge and experience from the river the moonlight and the Black Tiger Demon blood that now ran through his young veins.
