Rebirth of the Blade Breakers: side story

Because of her - A Mother's Day tribute

Kai switched off the television set and headed up the stairs, considerably stuffed after tonight's dinner. Rei had been over to cook that night, and whenever Rei cooked, he'd turn into a pig, so to quote from Takao. (Unfortunately to which he received a deathglare and a punch for his efforts. Poor Takao.)

He was passing his niece, Yume Hiwatari's room when he noticed that the girl was still awake despite the late hour that it was. No respectable girl her age would be up at this unholy hour... what the hell... Rubbing his eyes sleepily, he stood at the doorframe to observe what she was doing before deciding on a course of action.

Her Beyblades were all poured out on the bedspread; it was obvious she was racking her brains as to which was the best combination someone at her level and experience could obtain. She was confident, always wanting to push the limits of her abilities to breaking point. Just like me before... Kai thought sadly. I just hope she won't make the same decisions I had back then...

"Shoot..!" The soft command would have been passed off as the wind to the untrained ear. But Kai was a mercenary, he had been trained to pinpoint sounds. He knew she would be training at this hour. She always did, especially if she couldn't get to sleep, which was rather often for someone her age.

"Need help sleeping?" Kai asked, finally making his presence known, at the same time walking slowly into the girl's room, careful not to step on anything as he went.

A look of defiance came into the girl's eyes. "No. I'm fine." With that her hand went back to modifying her Beyblade. Then she lifted her head slightly. "Thank you for asking."

Kai smiled softly and sat down in front of her, clearing the Beyblade parts and dropping them into her toolbox. "But it's late." He laid a hand on her head. "You should rest, you still have school to go to tomorrow morning."

The girl groaned.

"You don't want to be late now, do you?" Kai grinned at that, remembering how much she hated her school's discipline mistress.

"Can I don't go?"

Kai put a finger on his chin in a mock gesture of deep thought before replying. "Don't you have a test tomorrow?"

The girl groaned again.

"I trust that you've studied for the test. Now off to bed..."

The girl nodded, packed her parts and climbed into bed, letting Kai pull the covers over her. Kai pulled the chair from her desk and sat beside her bed, softly stroking her hair, until she slowly fell asleep.

It was then that he acknowledged Rei's presence by the door.

Rei padded into the room softly, careful not to wake the girl. She was almost like a daughter to him; as much as she was to Kai. He wrapped his arms around Kai quietly.

"Don't think I didn't notice you... I did..." Kai said hoarsely, running his fingers over Rei's arm. "I didn't want to get distracted in front of her..." He heard Rei draw a sharp breath. "You know how I can get when I'm distracted..."

Rei snickered, then averted his attention to the sleeping figure. "...You know, I sometimes fancy us as a family... and a family can't run with a father alone... the love of a mother is also important..."

Kai laughed softly. "What are you hitting at, Rei? That I'm a mother figure?"

Rei snickered again, then buried his face into Kai's hair which was freshly washed. "Uhmm... maybe... maybe not..."

"You bastard..." Kai whispered. "But I still love you..."

Rei smiled and sat on Kai's lap. "I know." He said, kissing Kai softly on the lips.

From the bed, a smile could be seen on the supposedly sleeping figure. With the knowledge of what the two were doing, Yume held back a snicker, lest she should be scolded by the two adults.

Just as he was about to leave the room, a faint whisper caught Kai's ears.

"Oyasuminasai Kai-tousan, Rei-tousan. I love you..."

A soft, gentle smile on his face, Kai returned the response, Rei's voice accompanying his.

"I love you too Yume."
