Kyra is Boris' daughter
Her bitbeast is Zhar-Ptitsa

Kyra awoke in Kai's arms, she noticed he was still asleep. As she lay there, her head resting on his right arm, his chest against her back, his left arm wrapped around her waist, and their legs entwined, the events of last night played in her mind.

Kyra met Kai in the abbey and were best friends.
One fateful day, Kai escaped. 2 years later she escaped the Abbey too and as luck would have it, Mr. Dickenson found her, who took her under BBA's wing. She was trained there some more, isolating herself from the world, just like in the abbey, because that was the only way of life she knew, and became one of the best bladers they ever produced. She spoke to Mr. Dickenson about meeting Kai, she was nervous; she didn't know how he'd react when they finally met.

She arrived at the dojo, late in the evening and peeked inside, the Bladebreakers were training; Tyson and Max were battling, Rei cheered them on and Kenny was typing away fervently at his laptop. Her eyes searched for Kai, she saw him sitting under a tree, arms crossed at his chest, eyes closed. "Typical Kai", she thought with a smile.

Kyra had a whirlpool of emotions going through her mind; anger, fear, excitement, nervousness, longing, an unexplained desire. None of which she could completely comprehend when their meeting was so near in the future.

Kyra waited for Kai to be alone. A few hours later, she saw Kai walking outside, his blade and launcher in hand, launching his blade and having it circle around the tree for a little warm up. She launched her own blade, and at it hit Kai's Dranzer, both the blades flew back to their owners – Kai looked up; shocked.
"Hi Kai, remember me?" Kyra stood in the entryway of the dojo and begun taking small steps towards him when they had eye-contact.
Kai stood rooted to his spot, his mind buzzing, he knew her, those eyes, he could never forget those eyes, and that crazy purple hair...
She stopped a few steps away from him, and smiled at him.
That smile rung a clear bell, "KYRA?!" he blurted out with equal amounts of surprise and shock ringing in his voice.
"Oh, so you do remember me! Where the hell was this when you left me, all alone, to die in that shithole?!", she shouted , and punched him hard in the chest.
Her punch caught him off guard and he almost stumbled and took a step back, it looked like she was going to hit him again, he was ready for it this time, he caught hold of both her wrists and pinned them behind her back.
"Let me explain", he said in an urgent tone, that seemed to work. Her shoulders relaxed and her breath slowed down a little bit. He released her of his death grip

" I never meant to leave you, when Black Dranzer exploded, it destroyed the whole underground lab, it scared me, I was only 7, I didn't know what to do, 10 seconds later, I saw the guards coming towards me and I panicked and ran. I didn't even know which way I was going, I wasn't even planning to escape the abbey at that point, I just needed to get away from there, I honestly didn't know I'd be able to escape from that horrible place at the time, I didn't even know I had escaped before I stopped running to catch my breath!" he looked over at her, her expression read 'murder' and she was glaring at him, he continued anyway, "I'm sorry, I really am, I wanted to come back and get you, believe me, you were the only person back there I actually liked and was really friends with, I just didn't know how to get back without getting caught and getting both of us in trouble, they had seen me run away"

That softened her expression, but she still looked angry, "You leaving didn't piss me off half as much as you leaving without telling me or atleast making a plan together", she said as she crossed her arms, " I didn't know the details, they never told us anything. They just said you destroyed stuff and left". She rolled her eyes, "Dad made it painfully clear you planned it". "I did not!" Kai cried in frustration. "I know that now"
"Wait, how did u leave? You escaped, didn't you?"
"Yeah, pulled off the same stunt you did"
"WHAT!?"
"Yeah, they made a Black Zhar-Ptitsa and I tried to use it, but it blasted everything, and I left before they realised who did it"
"Are you crazy? Why did u try it at all?"
"I planned it"
"Mine was a total fluke, why did you deliberately put yourself in danger?"
"It worked for you, I took a leap of faith" she shrugged.

They stood there on the concrete, next to each other, looking up at the stars wordlessly; it felt like old times again.
Kai broke the silence, "You've changed" he said.
"How?"
"Well, your hair is longer" he smirked, running his fingers through her hair, and tucking a lock of hair behind her ear, his touch sent chills down her spine and a blush creeped up her face, she didn't even try to hide it. His hand lingered for a moment before it went down to hold her hand, she looked up at him, he pulled her into an embrace, his arms wrapped around her waist. She couldn't help but fall into it; she wanted to push him away but melted into the warmth of his sculpted body.

The next morning, she woke up in his arms.

Kyra turned her head a little to the side, and saw Kai's sleeping face, he looked so peaceful, like an angel. She slid out of his grip, reached over, planted a soft kiss on his cheek and ruffled his hair affectionately, which made him rustle in his sleep and lay on his back.

Kyra kissed him along his jawline and went lower, leaving a trail of kisses on his torso until she reached his manhood, which was slowly growing in length from the treatment the rest of the body received. She licked the whole shaft swiftly, till it was wet, before stroking her nipples with her fingers and lowering herself on to his cock and placed it between her boobs, it fit in nice and snug. She held her breasts with either hands and started an up-and-down rhythm, sucking the head of his dick, making little circles on it. Kai let out a soft moan and roused from his sleepy state and looked down at Kyra, giving him a titjob and half a blowjob at the same time. He looked half-surprised but just rested his back on his pillow as he smiled at her and she winked in response. He moaned again, louder this time, urging her to continue and she increased the speed of sucking his dick and took it deeper in her mouth.

Kai pulled Kyra up and got her on top of him and kissed her neck and ran his tongue slowly and seductively across her shoulders as his hands caressed her curves, making her shiver. He shifted from under Kyra and placed her to his left, his chest against her back and squeezed her ass. Kai stroked his dick once lifted Kyra's right leg up and entered her, making her let out a pleasurable groan and bite her lip as Kai fucked her hard and deep and she moved her hips to match his rhythm.

Kai lifted her up and carried her to his desk. In one sweeping motion, he threw everything off his desk and plopped her down on it, making her giggle. Kai attacked Kyra's lips, leaning forward, making her lie down on the desk with her legs hanging off it and her hands gripping the sides of the table. He positioned himself between her legs, taking her feet in his hands, sucking on each toe seductively, and tickled her feet while doing that, making Kyra squirm, laugh and screech all at once.

He spread her legs and placed each one on either shoulder and pulled her closer to him, so half her back was lifted off his desk and her hips were angled upwards, he rubbed his fully erect dick in a vertical motion at Kyra's entrance before gently sliding it in, making her moan. Kai pulled out agonisingly slow, for her anyway, before slamming into her again, rougher this time. Kyra's right hand was holding the edge of the desk and with her left hand she held Kai's muscular right arm, digging her nails into his skin, dragging them down his arm, making faint white lines in the flesh.
That was just the encouragement Kai needed and he slammed into her harder, finding her G-spot, and rammed harder still, making Kyra scream, "Oh! My God! KAI! Right there! Yeah!", Kai increased the speed of his thrusts, driving her crazy, little white spots began to form around Kyra's vision as she curled her toes and arched her back, moaning and crying in pleasure.

He decided to take things to the next level and adjusted her legs on his shoulders in a way that he could still be in control holding it with just one arm, slamming in and out of her all this time, and rubbed her clitoris with his middle finger. Kyra, not expecting this even the slightest bit, let out another scream of passion. She tried to keep her eyes open but it was getting increasingly difficult as she let out scream after scream of pleasure.

That pushed Kai over the edge and he let out a growl like and animal and a low-pitched "I'm gonna cum, baby!", "Me too!" she whispered, he could feel her legs shake at his shoulders and her vaginal walls tighten around his cock as she let out another scream and climaxed, his pace quickened and Kai pulled out just in time to shoot out his load all over Kyra's stomach.

Panting , Kai slid into a chair next to the desk. He looked over at Kyra and they smiled at each other,
"Wow!" she breathed, her voice hoarse from all the screaming, "Yeah", Kai said breathlessly. Kai winked at her and helped her up the desk.

"Now what?", Kyra asked Kai
"Now, we take a shower" Kai smirked mischievously and pulled her along with him into the bathroom.
