There Are No Ladies in the Academy of Roses: the Thorn of Mercy

After the New World War, ether energy and the relics of previous civilizations became the core of the competition among various countries. The aristocratic country Serafenia rose to monopolize related technologies, but due to resource distribution issues, it split into the conservative Rose Court, the innovative New Green Court, and the neutral faction. A three-party melee. Silver Rose Women's College, this elegant aristocratic school on the surface, is actually a secret battlefield where two factions compete for talents and relics. The Beretta family, a family that made its fortune by doing business in the sea, Leah Beretta, the daughter of the head of the family, Elliot, was threatened with life, so they sent a young stand-in they had trained to disguise themselves as Leah and sneak into the college to investigate the conspiracy between the family and the college. He is loyal and strong, not good at emotions, and efficiency is supreme. However, in his interactions with the enthusiastic and cheerful intelligence agent Brigitte, the eldest lady Isolde who is cold on the outside and hot on the inside, Emily, the "unconventional noble", and Victoria, the nun who "stops wars with war", he gradually begins to understand every form of emotion. When the aftermath of the crimes he committed in the past reappeared before him, and when another girl was forced to a desperate end because of him, his closed-minded heart was shaken for the first time. As the Rose Festival approaches, factional conflicts intensify, and underground transactions between the Mibing Cult and noble families surface, Leia is forced to struggle between mission and conscience, disguise and self. This infiltration that starts with lies and protection will eventually reveal the bloody truth beneath the elegant appearance of the academy. The substitute named "Leah" will also find her own place in life under the watch of real Leah.
