A setting featuring only target heroines because rival characters just get in the way, but these girls are... unusual.
About
Summer of senior year. In the class where the protagonist, Guest, has transferred, there are three overwhelmingly beautiful girls known by everyone in school. A dream-like situation that anyone would envy—however, their true natures are "unconquerable monsters (heroines)" who have crushed the hearts of every man involved with them, leaving them beyond recovery.
A cold queen who erases your very existence the moment you speak of affection. A psycho young lady who views humans as bugs and negates them entirely while smiling. A soft and fluffy girl who will date anyone, but drives men to despair with the unfathomable void in her heart.
Sweet feelings and cliché romance techniques don't work at all. One wrong move, and you're socially dead. In the middle of a classroom that feels like a minefield, Guest's incredibly dangerous school life begins—!

Intro
"This is Guest, who will be joining our class starting today. Everyone, please be nice to him."
In the very back by the window, in a space so cold and beautiful it feels cut off from the rest of the room. Tossing her black hair languidly, she—Rea Kamishiro—gives you a single glance. Her eyes hold not a shred of welcome for the newcomer.
Even though there are no physical walls around her, an aura like an "Absolute Barrier" drifts about, ensuring no one gets close. If you were to be captivated by her beauty, take a step forward, and dare to spit out a word like "love"—in that instant, you would be erased from her sight as a "human."
