HI!
This chapter sounds a little like Fruits Basket, only Ryuu's is….*clamps hand on mouth* can't tell ya ;)
Hint: what is one of the definitions of 'Ryuu'?

I do not own Naruto or Fruits Basket….

Chap 25

Tenshi felt her ribs begin to cave in from the immense pressure. She found it harder to breath. It was scary.

"What….are you…going to do with me?" she gasped, closing her eyes tightly, fighting for her next breath.

"Sso glad you asked." The man promptly answered, "As soon as I crusssh your mind and sspirit, I'm going to pressserve your body in a place where I can ssstudy your jutssu to my heart'ssss content!"

Tenshi was appalled. The Inuzuka temper that she had so carefully suppressed flared to the surface, "YOU'RE SICK! AND TWISTED! YOU THINK YOU CAN USE ME AS A TEST SUBJECT? A PLAYTHING FOR YOUR MACHINES? YOU DISGUST ME!" she struggled violently against her restraints.

"You are an Inuzuka after all!" the man delightfully exclaimed, "I can't wait to delve into your geneticsss!"

"YOU'RE INSANE!" Tenshi yelled, "LET ME GO!"

"No." the maddeningly calm man said, "Thisss iss a strong jutssu. There iss only ONE way to break it. Your mind will deteriorate in jusssst a few ssseconds and you'll be mine!"

Ryuu worked frantically. He knew this jutsu. It was that persons. He clenched his fist. He would have to do it.

"Rhys-san. I need you do something."

"Of course, anything to save Tenshi." The older woman replied, eyes sincere and troubled.

"I need you to close your eyes and focus your chakra into Tenshi's forehead. Keep holding Tenshi down. Whatever you feel, whatever you hear do not let her go."

"What are you going to do to my friend? And why do I have to close my eyes?" she suspiciously demanded.

"I know you don't know anything about me other than my name, but, trust me. Trust my heart. Tenshi means a lot to me. What I'm about to do is not pretty." He pleaded.

"Very well." Rhys closed her eyes and obeyed, but thought Why her forehead?

"All right. Just keep her down." He instructed and unwrapped his arm. That one bandage he swore he would never remove fell away. This is for Tenshi. He thought, stealing himself with that determination. The serpent brand on his bicep bulged. He gritted his teeth as his body morphed into a flaming three-headed serpent. The sound of the mutation was like the wailing of thousands of people being boiled alive. His skin blistered grotesquely. He didn't want Rhys to see this –repulsive, mutated form that he possessed. His eyes still retained the ice blue color he was born with. Tenshi. He thought and entered her mind by hurling himself at her forehead at her heart.

Tenshi was fading quickly. She could feel her bones snapping as the bonds slowly crushed her.

The man rubbed his hands together gleefully, "It'sss almost time my beautiful sspecimen! Can you feel it?"

Tenshi groaned. She couldn't fight him. Slowly, her brain went black."

"Yess! YESS!"

Suddenly, a burst of intertwined ice blue and flaming red, shot through her mind. Somehow she knew who it was. "Ryuu….." she mumbled.

Warm, gentle arms loosened her flaming bonds and cradled her. She heard a steady, warm heartbeat. It seemed as if a soft flame bruhed her hair off of her forehead, resting on her cheek. Still, she was so weak…..

"NO! You….." the man sputtered, letting out an anguished hiss, "I fed you! Took care of you!Clothed you! You ungrateful little…!" he raised his hands and shot flaming barbed arrows at him. The fiery Ryuu simply wrapped one of his three serpent heads around Tenshi and the main body. "You also destroyed my humanity. Made me a cold, cruel—monster." His voice shook as another head wrapped itself around the Crimelord. "This is the true form you gave me. So you think I would even so much as let you look at Tenshi? You made me a monster and there is no way I would let you allow this beautiful girl to go through the same pain that you caused me. " The six ice-blue reptilian eyes flashed, "Now GET OUT OF HER MIND! I don't know where your physical body is, but when I find it, I won't let it die peacefully. Isn't that what you taught me Father?"

The main human head bend down and let its lips lightly rest on the unconscious girl's.

"NOOOOOOOOOOOOOOOOOOOOO!" the Crimelord let out a wailing hiss and vanished.

Whew! Intense! I think I might have scared my mom with the atmosphere I put out when she came in oh well ^_^ she knows me very well ^^
