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.
