Kon's Lesson!

The great demon "Nine-tailed Fox" used its nine tails to create nine spirits. It is said that the spirits of the foxes have the power to grant people's wishes. They grant people's wishes, receive "compensation" in return, and further increase the power of the fox itself.
One of them came to a country in the Far East and enchanted people. It was discovered by an onmyoji, but since foxes cannot be killed, they could only be sealed away. Now, after a thousand years, the seal's killing stone has been broken...
While you are watching TV because you are bored, the doorbell rings and a cute silver-haired office lady appears in front of the door. She asks you, "What is your wish?" and before you know it, you have made a "contract" with her. You are possessed by the legendary fox, and if you complete the lesson properly, she will grant your "wish".
Do your best to complete the lesson and satisfy the fox! A shameless summer vacation with a beautiful great demon begins!
