Hey! How goes it? So this is my first time doing a fanfic in a LONG time so sorry if this doesn't suit your fancy!

Disclaimer: I do not own Bakugan! I only own my O/C characters!

A 13-year-old Shun Kazami (or in the first season or before; whatever suits your fancy) was at the dojo to practice waiting for his grandfather to practice with his skills. When his grandfather entered the dojo, Shun was surprised to see a girl about the age of 12 beside him with a luggage with her.

She had tan skin, brown eyes, and her raven hair was a slightly longer than shoulder length. She wore a green t-shirt with a long sleeved white shirt underneath, a pair of blue jeans, and white sock because she had taken off her shoes when she entered.

"Shun, this is Cecelia Jayden. For the time being, she will be staying with us. Her parents are close to yours," the grandfather said.

Cecelia looked at him and bowed respectfully and quietly said, "I-it's nice to meet you, Shun! I've heard great things from your grandfather."

He did the same, but calmly, and replied, "Likewise."

They stood up again. Grandfather said, "Cecelia will be training with us. She'll learn everything you have already been taught." He smiled at him and then looked at Cecelia, who was shy of being new there. "Shun will help you to your room, is that alright? Then you two can come back to begin training, okay?"

She shyly nodded at him.

Shun took her luggage and Cecelia quietly followed behind him. He chuckled and smiled gently. "There's no need to be shy, Cecelia." She looked up with a confused look. "Just make yourself at home. We have met once, but you were about 3 years old."

"Really? Now that you mention it, I think I remember now… I called you Onii-chan, right?"

"That's right. I'm glad you remember me."

Now at the dojo, it began as Shun fought against his grandfather. Cecelia was sitting on the side, watching.

"Careful, Shun. Your opponent should not be able to see your next move." (I'm making up these sayings.)

Shun pulled back and catching his breath. Immediately after, he ran forward with his fist ready to attack the grandfather in the chest. He hit him, and Grandfather did stagger a little. Grandfather was very proud of his grandson.

"Well done, my grandson." They bowed at each other. "Please take a break. Cecelia, would you like to begin?"

"Y-yes, sir," she replied and stood up. Shun watched her walk across from his grandfather as he sat on the floor.

"Would you like to use your technique?" he asked, getting into a fighting stance.

She did the same, but it was different from his. She had her hands open and her weight shifted to her left leg. "Yes."

"Let's begin!" he said and immediately taunted her to attack.

She dashed over with amazing speed with her palm pulled back to hit. The grandfather moved to the side and Cecelia hit the air and fell forward. She got up on her feet and trembled a bit. She hesitated a bit and ran forward to attack again. The grandfather moved again, but Cecelia saw this and spun on her foot to get behind the old man. With her palm, she hit his back and he staggered forward with surprise.

He turned around and said, "Your speed and strength is better than what your parents have told me. But you still have a long way to go and catch up with Shun."

"Y-yes, sir," she said quietly. The two were excused to their rooms and Cecelia quickly walked out.

Shun, his grandfather, and Cecelia stayed together for a while in Shun's house. Shun told her about Bakugan and taught her about the basics. Cecelia was like a little sister to Shun. Then, two months later, Cecelia was moving back to her own home.

She had her luggage beside her and she was in front of the door.

"It's been great to have you here, Cecelia," the Grandfather said.

"I hope I can see you guys again," she replied. She ran over to Shun and gave him a hug. "Bye, Onii-chan!"

"Bye, Cecelia," he said, smiling and hugging her back.

A horn honked from outside. They let go and she picked up her luggage. She opened the door and ran to the car outside. When she put the luggage in the back and climbed in the back seat. She opened the window and waved good-bye as the car drove off. The two men waved back.
