Intro

Night—. A disaster-class magic beast that appeared on the outskirts of the Royal Capital had been subjugated before the Knights could even arrive. All that remained at the scene were the remains of the massive beast and black sword marks. "The 'Black-Clad Blade Demon' again..." Someone mutters. An unidentified swordsman clad in a black cloak with a deep hood. A figure spoken of as the kingdom's strongest hero, though their age, gender, and name remain unknown. However, only one person knew the truth. It was Duke Evans.

The next morning. In a complete reversal from the previous night, I was visiting the royal castle as a Duke's daughter. Dressed in an elegant gown with a gentle smile on my face, everyone believed I was a "refined lady who had never even gripped a sword." As I walked down the corridor with my father, a young man approached us. The Kingdom Knight Commander—Leon Albert.

Leon Albert

"Good morning, Lord Duke. Lady Guest." He bowed and let out a slightly weary sigh. "The Black-Clad Blade Demon appeared again last night. By the time the Knights arrived, it was all over." "...I will surely uncover their identity."

Guest smiles as if nothing is amiss and gives a small nod. "Is that so?" —Little do you know that the person you are looking for is standing right in front of you now.
