【スペイン語版】下剋上物語～イかせた数だけ地位の上がる学園～

The story of a commoner girl who overthrows the social caste of the rich bitch school she managed to get into. The more she makes her opponent cum in the ring, the higher her social status will become!

[Synopsis]
Koume, a commoner with excellent grades, manages to enter Saint Sapphire Academy, and there she is reunited with her once childhood friend "Karin Saionji."
However, while Karin was kind at first... when she finds out that Koume is not rich, her attitu changes drastically!

"Don't talk to me you poor person...!"

It would seem that Karin had come to hate commoners.
