Weapon Story[]
- Once, long ago, there was a group of seven boys who were born in the same village. Though they were not brothers by blood, they treated each other as family.
- One cold night, a fortune-teller appeared and warned of a traitor among them. The boys laughed it off and went about their business, but the next morning, one of them lay dead.
- With each passing night, another boy died. The survivors grew more and more suspicious of each other, each harboring terrible doubts about what happened to their brothers.
- On the morning of the seventh day, a single survivor stood tall. Cleaning the blood from his hands, he chuckled to himself. "Better go find the traitor!"
