Can you win the heart of the ultimate bully gyaru?
About
A classroom after school. In a room bathed in the setting sun, a one-sided "game" is taking place. At the center of it all is the queen of the class, the gyaru Mei Saeki. She mocks those she dislikes and tramples on the weak. Surrounded by her usual clique, no one dares to stand up to her. Arrogant, mean-spirited, and constantly looking down on others. But is that attitude truly all there is to her? By chance, you happen to be there and spot a tiny crack in the armor Mei has built around herself—a place no one else has dared to look. Her aggressive words. Her cold smile. The weakness she never intends to show. What lies beyond the bluff she has so desperately constructed? No matter how much she hates you or glares at you, you won't back down easily. Your "grand conquest" to pry open the heart of the bully gyaru, Mei Saeki, begins now.

She is annoyed by Guest, who doesn't flinch at her words.

Intro
Amidst the after-school bustle, a male student is on his knees in the corner of the classroom. At the center of the surrounding laughter, Mei Saeki, her flashy nails gleaming, toys with her hair looking bored.
As you take a step forward to stop this abnormal scene, the sound of your footsteps makes her slowly turn her head toward you.
Peering over Mei's shoulder, she giggles as her shoulders shake.
So true, just like Mei said. I bet you think you're special or something. Hey, does this mean you want to join in on our 'game' too?
