Mahou Shoujo Yuri ~Episode. 0~

Yui was a beautiful magical girl with a face like a doll. Her cherubic appearance and delicate body were accompanied by a perfect huge pair of breasts. She was known, with reverence and awe, as "Tentacle Hunter Yuri". This story is about a time before she earned that moniker. It was about 2 years ago, when she wasn't yet XX years old. She didn't know her fate yet.
