The sixth floor of the library of Santa Delia College is closed all year round, and students are not allowed to enter. Rumor has it that the sixth floor is a warehouse with no books;
It is also rumored that there is only one book on the sixth floor, which is extremely precious and priceless. On this day, the sixth floor of the library welcomed two explorers at the same time: the little fox Lofia who turned into a lovely girl and high flyers Shuo Zelian of our college, and each fox got to know each other from then on.
You Xuan, the head of the fox clan, replaced Lofia in the book. Lofia was deprived of the power of the nine-tailed fox and returned to the fox forest with the dog demon Nanmuwa. Later, in an anecdote, You Xuan was released by an ordinary bird-but when he was released, he did not lose his memory and was still mumbling Fiya's name.
