Tsunami of Dead Tears: Part 2

Chapter 24

Kaigaku charged.

The Upper Moon burst into a front-leaning sprint, maintaining a superhuman level of balance. Finally, he dashed forward and swung with an upwards strike. Zenitsu dashed forward as well, bashing Kaigaku's blade out of the way and countering his now-defenseless neck with a quick diagonal slash , creating a small cut, barely even enough to decapitate Kaigaku. Zenitsu grit his teeth in frustration and stepped back as Kaigaku swung again.

The two of them stumbled under their feet, steadying their balance, then faced each other once again. 

This was how duels went. A flurry of parries and snaps at the opponent, swordplay at it's purest. It was less a fight, more a dance. Once the fight dragged out a little longer, that was when both fighters would show their true skill with the sword.

After a brief moment, Kaigaku bolted into action once again. He raised his blade in a rapier stance and delivered two quick stabs aimed at Zenitsu's chest. Zenitsu parried both of these attacks, but his eyes widened in shock as Kaigaku spun around, and a SECOND sword was in his other hand, swiftly descending straight towards his forehead. Kaigaku had grabbed one of the many katanas that were stuck to the floor, distracting Zenitsu with the stabs. Zenitsu raised his own blade, trying to block the incoming strike, and failing. His posture was too weak. Kaigaku's second blade impacted with Zenitsu's, but since he wasn't as strong, as the blades collided, the back edge of his own blade smacked to his own forehead, leaving an ugly bruise that managed to split his skin. Zenitsu stumbled, then collapsed, clutching his now-bleeding forehead

Behind him, Nezuko clenched her fists. The exchange had been so fast, and she wasn't able to contribute to anything. With anger -and a little bit of guilt- in her heart, she took a katana from the ground and walked over beside Zenitsu, who was still kneeling, covering his increasingly bloodied head.

Kaigaku grinned, then tossed away the blade as he took a nonchalant stance. "You sure you wanna hold that thing? It's pretty dangerous for someone like you."

Nezuko placed the blade on her wrist and made a deep cut, soaking the edge in her own blood. She winced slightly, but kept her eyes open. "That goes for both of us."

Nezuko's beautiful voice...  Zenitsu thought in silence.

Nezuko clenched her fist, and her blade erupted in pink brilliance. Her Blood Demon Art had been triggered.

She snapped first, swinging a fast, right-handed attack at Kaigaku's face, the pink flames illuminating the sword's path. Kaigaku parried it with a left-handed block, then began to motion a stab towards Nezuko's chest. She saw this, then grit her teeth as she plunged her left hand at the incoming stab. Kaigaku's blade pierced her palm, penetrating flesh, joints, and bone, and soon protruded out the other side of her hand.

Nezuko smiled.

She spun her sword, which was in her right hand, and squeezed it firmly in a reverse-grip. Kaigaku's blade was still embedded in her left hand. The flesh around the stab wound quickly regenerated, wrapping and binding around the blade, holding it like cement. Kaigaku gasped as he realized what she was doing.

In a flash, Nezuko tugged Kaigaku towards herself, his blade tugged along with her hand in an iron grip. Planting both of her feet firmly onto the ground, she brought her right arm up high, which was the arm that held her Nichirin blade, and slammed the sharp fiery edge of her sword along Kaigaku's face. It left a bloody gash on his cheek, Nezuko's Blood Demon Art transferring from the blade unto his skin. 

He couldn't use his right arm to block her swings, as while she was bashing her sword at his face, she made sure to keep his left side facing her, rendering his right side useless. She didn't stop swinging.
