The begining part 1

Seven year old Riku stared out at the ocean, watching a small island that sat in the distance. His silver hair blowing in the wind.
“Hey Riku!” Sora called. “Whatch ya doing?” He asked sitting beside his friend.
“Sora see that island way out there?” Riku pointed into the distance.
“Ya what about it?”
“I think it would be a cool place to you know hang out and have our own secret hid out. We should go there one day and explore I’m tired of the main land.”
“Maybe.” Sora said. The two small boys sat on the dock watching the ocean.
On the other side of that island a black ring appeared on the ground. It began to ripple like water as something emerged to the surface. A girl was kneeling on the ground. Both her hand lay on the ground. In one hand was an unusual blade. It was called the Heartblade. She was panting hard. Her blade looked just like a Keyblade only it had hearts on it. Her long black hair blowing softly in the gentle breeze.
When she was able to breathe normally she reached into her pocket and pulled out what looked like some kind of communication device. It was in the shape of a Mickey Mouse head. She pressed a button and it opened. She presses on the small black screen and waited.
“World connected.” Said a small voice. The screen went white before King Mickey’s face appeared on the small screen.
“Hello? Tenshi?” He called.
“I’m here.” The girl said, Tenshi was her name.
“Have you found the key?” Mickey asked.
“Yes your Majesty I sense them both. They’re a bit too young to be of any use right now.” Tenshi said.
“Right use the time to prepare them for what lays a head.” Mickey said and the screen went black. Tenshi closed the device and stood up. She extended the blade out in front of her and it disappeared.
“Now for my home.” Tenshi said. two white wings appeared on her back. Tenshi stared up at a large tree before her. She gathered all the broken branches and drift wood on the island and used her power to construct her self a tree house. Seeing as she could fly Tenshi didn’t bother to create a ladder.
Tenshi sat in her new home staring at three photos. One was of Seven year old Riku, her hand gently touched the photo.
“You will be trouble.” Tenshi said to herself. The other two pictures were of six year old Sora and six year old Kairi. Tenshi looked to be around seven just like Riku. She sat on the bed she’d created for a few minutes before moving.
*I need to find the best way to make myself their friend.* There was a swirl of magic and Tenshi disappeared. In her place was a swan. She flew to the main land and immeditaly spotted the two small boys.
*Looks like those two are already friends.*
