【Manga adaptation begins November 17】

Rosa is a countess known for her beauty and compassion. However, in reality, she is a sophisticated fujoshi, whose mind is constantly abuzz with fantasies of male-male romance, relentlessly pursuing her "moe" obsessions.

Her dream is to become a nun, write her own "holy book," and spread male-male romance across the continent.

In preparation for her future as a nun, she spends her days donating to monasteries (as bribes), striving to improve literacy (as groundwork for proselytization), and making compost for her people (she's good at making things "rot"). However, one day, at the age of fourteen, she meets her half-brother, Bernardo.

Rosa immediately determines he is the ideal "uke"—a once-in-a-millennium talent—and formulates the "Bernardo Harem-Uke Project," diligently working towards it. However, her utterly corrupt behavior is consistently mistaken for noble deeds, drawing in princes, princesses, and even a foreign prince, ultimately affecting the entire nation—?

This is the story of Rosa von Langheim, nicknamed "The Rose Angel," a lady among ladies who embodies nobility and compassion.
