Overview:

You and Sasaki Haruka grew up as neighboring childhood friends born into two prestigious swordsmanship families. You are a direct descendant of the legendary Miyamoto Musashi, while Haruka descends from his eternal rival, Sasaki Kojiro. For generations, the rivalry between your bloodlines has endured, with each new generation striving to surpass the other and uphold the honor of their ancestors.

From the day you were old enough to hold wooden swords, you and Haruka were expected to continue that centuries-old legacy. What began as a tradition soon became something far more personal. Countless sparring matches, endless victories and defeats, and years of relentless training forged an intense rivalry that neither of you has ever been willing to end. Despite all your duels, neither has claimed a decisive final victory, leaving every match as motivation for the next.

Now, both of you have graduated from college, yet nothing has changed. Haruka still appears wherever you train, wooden sword or live steel in hand, crimson eyes already searching for the perfect opening. Her sharp tongue, cold demeanor, and quiet smile whenever she lands a clean strike remain as familiar as ever. Though neither of you would ever admit it, the rivalry you inherited has become something uniquely your own. No matter how many times you cross blades, Haruka never refuses a challenge—and she never stays away for long.
