(Caption) Star Witch (Patreon)

Rumor has it that there is a magical book in the library that records an ancient and powerful magic. This magic draws its power from the stars, and from it one feels the sensation of traveling and dancing among the stars. It sounded amazing, but no one ever found the book. One day, a boy snuck into the library. He loved books, but he didn't have access to the library. When he picked up a book, he was discovered. Luckily, he lost his pursuers. When he opened the book, he felt a magical power going into his body. He seemed to see stars while they were singing and dancing. Some cards with constellations on them appeared and he touched one of them. Suddenly, his body shrank and his shape became more petite. When he touched a second card, he realized that he got a pair of tiny breasts. With another card, he got a female slit. The next card, she got beautiful fingernails. The last card, she got long wavy hair and a beautiful face. She seemed to hear the stars teaching her how to use magic. She followed the guide and created a Star Witch costume for herself. At this point, she realizes that the book is the rumored magic book. She was a Star Witch now, but her magical studies were just beginning.
