Saizou grinned as he stalked towards Tsukune and Moka. The pink-haired girl shivered as she saw the hungry look in Saizou's eyes. Tsukune had come to rescue her too, despite the fact that he was human. They were friends so that was all that mattered. She didn't care that he was human. However, because of her, she was going to die.

"Moka-san, I'm sorry," he apologized, "I'm sorry for just leaving you like that and for what I said. Can you forgive me?"

"Of course I do," said Moka. "You're my first and most precious friend."

"Thank you," Tsukune smiled.

"What a sweet little scene. Too bad I have to kill you now!" roared Saizou. He lunged but then suddenly a small red metallic bird collided with his face, sending the orc staggering backwards. "What!?"

Tsukune smiled. One of his scouts had returned. It swooped down and Tsukune held his hand up for it to perch on his palm. "Good job," he said to the small metallic hawk. Moka gazed upon it.

"What is that thing?" she asked.

"My Disc Animal," said Tsukune.

"Disc Animal?" Moka blinked.

Tsukune looked serious and said, "Moka-san, I wasn't completely honest with you. It's true that I'm human, but I'm also…" He drew a tuning fork with an Oni's face on the handle. He tapped the tuning fork against his watch, "An Oni." He stood up, letting the hawk-like Disc Animal fly off before holding the tuning fork up against his forehead. Vibrations from the tuning fork began to sweep over Tsukune as an Oni's face appeared on his forehead. Then, much to Moka and Saizou's shock, Tsukune's entire body became engulfed in violet flames, burning off his clothes. Also, he began to moan and moan louder and louder before…

"HI-YAH!" Tsukune exclaimed, throwing one arm to the side to disperse the flames and reveal his true form. He was covered in a skin tight suit of body armor that was pitch black. There was also a silver vest with a furry collar worn over the suit. A pair of purple gauntlets with silver trimmings also covered his hands up to his elbows. He also wore matching purple boots that went up to his knees. Around his waist was a belt with a buckle that resembled the front of a Taiko drum. Hanging at his hip were disc-like objects. In holster in the back of his belt were a pair of Taiko drumsticks, topped with Oni heads. Finally, he wore a 'mask' that had no face but it had purple facial markings like the makeup of a kabuki performer. He also had a pair of short silver horns.

Saizou and Moka gawked at Tsukune's new appearance. "AN ONI!?" Saizou shouted.

Tsukune looked to Moka whose mouth was gaping open with shock. "Stay here," he advised. He then went towards Saizou.

Saizou sneered. So the little whelp was a monster with a true form after all. So what if he was an Oni? It didn't matter to Saizou whatsoever. The whelp still looked scrawny and weak anyway.

Saizou threw a fist but then Tsukune caught the fist and twisted on his heels before tossing Saizou hard to the ground with a judo throw. Moka was shocked. Had Tsukune been holding back his true strength?

"Damn you!" Saizou growled as he clawed at Tsukune who stepped back. The orc got back to his feet and then started to claw at Tsukune but the Oni-boy dodged each of the clumsy strikes. It was a good thing that Tsukune was in the forest. This was an Oni's true element and Tsukune had the advantage here.

Tsukune called out, "Kiboujutsu Onidume!" Suddenly, claws sprouted out of his knuckles and he stabbed them into Saizou. The brute grunted in pain before Tsukune used a palm strike to send the monster staggering back. Then, he called out, "Kiboujutsu Onibi!" A mouth formed on his mask and fired a stream of violet flames at Saizou. Saizou let loose a scream as the flames engulfed him. Satisfied, Tsukune made his way back to Moka. His head glowed with light and when the light subsided, his mask was gone.

"Moka-san, are you alright?" Tsukune asked politely. The girl nodded. He offered his hand to help her up and the girl stared up at this human and yet not-so-human boy.

"Tsukune…" said Moka softly.

"Moka-san," he replied, smiling.

"RARGH…!!!" Saizou roared loudly, ruining the moment for both teens. "DAMN YOU!!!" He was a bit singed from the Kiboujutsu Onibi, but he was still alive. Damn, his skin must be tough. He grabbed a large boulder and pulled it up over his had before tossing it at them. "DIE!!!"

"Watch out!" Tsukune shouted as he pushed himself and Moka out of the way. However, one of his hands accidentally grabbed onto Moka's rosario and it snapped off.

All of a sudden, Tsukune and Saizou were shocked by the sudden explosion of Yoki that was coming from none other than Moka herself. Her hair's color began to change from pink to silver as her eyes narrowed and the irises turned to red with narrow slits for pupils. Her skin also became paler. She also became even more developed as her bust-size increased. The Yoki was so immense that the atmosphere changed. Bats flapped around Moka as she stood arrogantly, with one hand on her hip and radiating with power.

This was Moka's true nature. She was a super vampire.

"No way! Those eyes and that intense demonic aura! You're the real deal! An S-Class monster! VAMPIRE!" shouted out Saizou.

Moka-sama ignored Saizou and turned her attention towards the mask-less Oni named Tsukune. "So, an Oni of Pure Sound in this place of all places. How interesting."

Tsukune gulped. Was this really the power hidden within Moka? It was incredibly frightening. "Moka…san?"

"You owe me and my other self answers, boy," she said to Tsukune. "But for now I need to deal with this pest." She eyed Saizou. "What's the matter? Didn't you want a hug and kiss me? Come on. I'm right here."

Saizou growled. So what if this bitch was a vampire? He would not be beaten! He let loose a roar and then lunged at Moka who just yawned. When he got close to strike, all of a sudden Tsukune pulled off his belt buckle and tossed it at Saizou. The belt buckle stuck onto Saizou's chest and expanded into a large Taiko drum. Moka cocked an eyebrow and turned to look at Tsukune who'd just drawn out the drumsticks, known as the Ongekibou Rekka, from the back of his belt. He then got in front of the immobilised Saizou and began his attack.

"Ongekida Ikki Kasei no Kata!"

With the Ongekibou Rekka, Tsukune began to beat the drum rapidly with them, causing Saizou's body to shake with each of the drum's vibrations. He picked up speed, creating a rhythm. As he was about to finish Saizou off, he was hauled backwards by Moka-sama.

"Allow me," said Moka-sama before she drew her leg back and kicked at the drum on Saizou's chest. "KNOW YOUR PLACE!!!" the kick sent Saizou flying and then finally there was a huge explosion. The buckle flew back to Tsukune's hand and he fitted it back to his belt. However, now he was faced with an angry Moka-sama. She grabbed him by the collar of his vest and shouted, "I am not some damsel-in-distress! I did not require your assistance!" before she pushed him backwards. She then reached down to the ground and picked up her rosario, "Remember to know your place. Just make sure to take care of the other Moka for me," she ordered before snapping the rosario back on. The intense aura receded into her body and she began to fall backwards as the color returned to her hair and skin.

Tsukune quickly caught the girl in his arms and cradled her gently. Moka was indeed a strange creature. Was she two people sharing the same body, or two sides of the same coin? He wasn't sure. The 'real' Moka was definitely more terrifying than the one he had befriended.
