Now it is said that if an oni's arm be cut off it cannot be made to unite with the body again, if kept apart for a week. So Raiko warned Tsuna to lock it up, and watch it night and day, lest it be stolen from him.

So Tsuna went to the stone-cutters who made idols of Buddha, mortars for pounding rice, and coffers for burying money in to be hidden away in the ground, and bought a strong box cut out of the solid stone. It had a heavy lid on it, which slid in a groove and came out only by touching a secret spring. Then setting it in his bed chamber, he guarded it day and night, keeping the gate and all his doors locked. He allowed no one who was a stranger to look at the trophy.

Six days passed by, and Tsuna began to think his prize was sure, for were not all his doors tight shut? So he set the box out in the middle of the room, and twisting some rice-straw fringe in token of sure victory and rejoicing, he sat down in ease before it. He took off his armor and put on his court robes. During the evening, but rather late, there was a feeble knock like that of an old woman at the gate outside.

Tsuna cried out, "Who's there?"

The squeaky voice of his aunt (as it seemed), who was a very old woman, replied "Me, I want to see my nephew, to praise him for his bravery in cutting the oni's arm off."

So Tsuna let her in and carefully locking the door behind her, helped the old crone into the room, where she sat down on the mats in front of the box and very close to it. Then she grew very talkative, and praised her nephew's exploit, until Tsuna felt very proud.

All the time the old woman's left shoulder was covered with her dress while her right hand was out. Then she begged earnestly to be allowed to see the limb. Tsuna at first politely refused, but she urged, until yielding affectionately he slid back the stone lid just a little.

"This is my arm" cried the old hag, turning into an oni, and dragging out the arm.

She flew up to the ceiling, and was out of the smoke-slide through the roof in a twinkling. Tsuna rushed out of the house to shoot her with an arrow, but he saw only a demon far off in the clouds grinning horribly. He noted carefully however that the direction of the imps' flight was to the north-west.
