The strongest underground fighter, known as “Princess Burst Yuki” or Sakurano Yuki, is also a hardworking soul who supports the family-like companions of the orphanage where she grew up with her fight earnings.

Then, an offer comes her way—a scout from the industry legend known as “King.”

For the sake of her orphanage family and, above all, to climb to the pinnacle of strength, Yuki steps into the ring to face King. But then…

“You set me up, didn’t you?”

The match with King, in its true essence, was a spectacle where the loser would be ravaged by King in front of a massive crowd as a penalty. With a grimace of frustration, Yuki is forced to take him in her mouth and, unbelievably, loses her virginity in full view of the audience. What’s more, she’s left speechless by the true purpose King reveals.
