Tessa, a high school student (Olivia Goncalves), falls asleep studying in the library to awaken in a dream where an ancient book appears before her. Upon opening the book, she discovers it is alive in the person of a young girl named Kang Yi (Courtney Zang). Kang Yi, the living book, tells the story of how she was chosen by the Great Bookmakers to become the chapter of Purity in the Eternal Life Book, and how she was protected and escorted by a legendary creature in human form (Ahura Z. Diliiza) and his apprentice (Nirakazi Ng).

To others, this being is known as the Unicorn, but to Kang Yi, he is Anikruya.
