| 74 land. | |
| 75 | |
| 76 It had many powers — the ability to shape shift, turn invisible, control | |
| 77 the elements. Its powers came from its majestic tails and the kitsune | |
| 78 guarded them ferociously. If any fox attained eight tails, it would battle | |
| 79 the kitsune for domination of the celestial world. To prevent this, the | |
| 80 kitsune stole the tails of all the foxes it encountered. | |
| 81 | |
| 82 The evil kitsune challenged every fox to a haiku contest. But the | |
| 83 competition was not fair, and the kitsune cheated every time. When it | |
| 84 defeated the poor fox, it stole its tail and threw it to the four winds. | |
| 85 | |
| 86 The kitsune stole your tail. Now it’s time to get it back. | |
