(...whoa. ......NICE!!!

Time for the actual battle...)
John brought his blade up, swinging it down from over his head. E.B. dodged to the side, punching John in the face. John brought the sword up, swinging horizontally, managing to slash E.B. in the chest. E.B. leaped back, and using shadow powers, fixed the gash. While he was busy healing himself, though, John ran at him, slamming him with the flat edge of the blade, right in the face, knocking him against the wall.
E.B. got up. "I will not let you win this time, X!!!" He put his hands toward the Millenium Ring, as he started casting magic. He created a barrier between John and the exit which he was running at, so John merely ran up it, turned around, and with a flip landed, rushing at E.B. again. This time E.B. brought out his knife, dodging John's sword and stabbing him in the leg. John screamed in pain for a second, then got up and knocked away the dagger with his blade. Bakura weaved in and out, dodging John's furious attacks, until he was stuck in the corner.
"I'm not hesitating to kill you this time." John attacked E.B., almost nailing him in the heart, but E.B. managed to duck and get out in time. Using a spell, he managed to force John still. He walked up.
"This is the end of your little charade. You're going to die, right here, right now." He walked closer. Out of nowhere, a six-pointed shuriken came and nailed him right in the arm. E.B. turned around, to see Nin, holding his arm but otherwise okay. This distraction released the speell on John, and John picked up his sword, stabbing E.B. right through the chest. Upon pulling the sword out, E.B. fell to the ground, clutching his chest.
"You moron, how could you do this?" E.B. got up, totally ticked off, and started moving toward Nin. When, a light glowed between them.
"Ninjitsu, this sword is for you. You might recognize it as the legendary sword of Muramasa. Use it. May God protect you all." The light disapeared, and the beautiful yet razor-sharp katana appeared at his side.
"Awesome." E.B. got close, but Nin whipped out the sword, unintentionally slashing him in his chest, making a HUGE wound. E.B. turned around, seeing John with the Angel Blade on his right, Nin with the Muramasa on his left.
"These aren't my kind of odds, I'm leaving." And, with that said, he disappeared.
