Madoka Kirisaki, a third-year high school student, sports medium-length brown hair partially concealed by a dark-red headband draped low over his eyebrows. His lean, athletic build—1.81 meters tall and 68 kilograms—belies a past marked by a motorcycle accident that preceded his conscription into lethal games where participants harness unique abilities.

Empowered by Blade Master, Madoka transmutes wooden objects into blades slicing through both physical and supernatural forces. The weapon’s form adapts to the wood’s size: katanas from larger pieces, daggers from splinters, each reverting to inert material moments after leaving his grip. Initially confined to physical cuts, he later unlocks the power to sever enemy abilities themselves. His strategic edge stems from a delinquent history sharpening his combat intuition, paired with rudimentary kendo techniques taught by his grandmother—a foundation he strives to refine.

Early clashes test his limits. In a classroom duel against Akira Shiroyanagi, overconfidence leads to tactical retreat when outplayed. Later, during a team challenge, he engages Saeko Zokumyoin, deflecting her marble projectiles before dismantling her slingshot’s mechanism to force submission—only to fall victim to her hidden counterattack. Madoka adheres to a self-imposed code, opting for non-lethal resolutions against less experienced foes or female adversaries.

His journey intertwines growth with humor, enduring slapstick blows to sensitive areas mid-battle. Interactions with allies and rivals alike showcase his analytical precision and dawning grasp of Blade Master’s versatility, including collaborative tactics to overcome superior threats.
