Shenron glided through the clouds above Other World. He was on his last day of his five day trip to earth. This would be the second time he went to earth without being summon. The last being a year ago when he took Goku with him to train. He kept a leisurely pace, being mindful of the precious cargo slumbering on top of his head.
She was the last glimmer of hope to stop the end of existence. Shenron know she couldn't do it alone. She wasn't a fighter, her approach was peaceful resolve. It would prove useless against her six counterparts. She would need the Z fighters.
He named her Kuu. He felt she was the only one who deserved to be named after Goku. She resembled him in many ways. Same goofy smile, same insatiable appetite, same spikey black hair, only hers fell in waves down her back.
"Kuu wake up. We're almost here."
She stretched her limps out before falling right back to sleep. He would have let her continue sleeping, but she would have been upset if she missed something this.
"KUU!" He roared.
"What!?" She shot up from her slumber.
"Wake up I didn't want you missing this."
She rubbed her eyes hoping it would help her focus on whatever he didn't want her to miss. Shenron dove down into the clouds below. Kuu squealed lifting her hands in the air.
"Look Shenron no hands!" She said mid squeal.
He couldn't help but chuckle at the nearly full grown woman squealing on the top of his head. Kuu tried grabbing the clouds as they burrowed into them. The two were consumed by a blinding light.
"Wow! Shenron look!" She crawled to the tip of his nose. "It's so beautiful."
They flew over a wide valley with vegetation that grew so wild it was climbing up the tall rocky cliffs. It was crowded by songs of bird's noises of wildlife, and the rush of water falling over a cliff in the war corner of the valley. He perched himself inside the valley. The trees snapped and crunched under his weight. birds flew out of the trees under him.
Kuu jumped off his nose and ran into the forest towards the waterfall. She threw off her bright orange cheongsam, and shimmied off her navy blue pants. She jumped into the water feet first. She floated to the top of the water.
"There's nothing better the feel of water against your skin." She said.
Shenron looked up at the sky. He could sense two energies heading his way. He knew if he showed up with Kuu, someone would find them. Goten was suddenly floating in front of Shenron.
"Shenron what are you doing here? Where's dad?" He asked.
Kuu dove into the water just as Trunks walked up the shore. He smirked as he recognized the spikey black hair under the water. He waited until the cloud of black hair emerged up to the surface.
"Welcome back Goku." Trunks said.
Kuu turned to face him. A wide grin spread across her face. She swam to the shore. Trunks eyes widen before he snapped them shut as Kuu ran up to him. She wrapped her arms around him soaking his clothes. She hugged him tightly; her head fit snuggly under his chin.
"Did I do something wrong?" She asked letting go of Trunks.
"No it's just." He opened his eyes, but shut them quickly when he saw she was still naked. He pulled his jacket off of him. He opened his eyes once more just to make sure he could wrap his jacket over her shoulders. His jacket fit loosely on her.
"I just thought you were a friend of mine." He explained.
I know I felt Goku's Ki coming from the water, but now it's coming from her. Trunks thought.
"I'm sorry. My name is-"
"-Trunks." Kuu finished.
"Do… I know you?"
"Yes… Well kind of. My name is Kuu. Shenron named me."
Trunks scratched his head. She didn't give him much of an answer. He waited for her to give him more information but she just stood there smiling at him. His jacket hung open around her. He began to button it up.
She has no shame does she? He thought.
"Why'd you do that? I'm going to go back into the water. I never go swimming with clothes on." She said pulling his jacket off and handed it back to him.
"Thank you but I have my own clothes." She jumped into the pool.
"How do you know my name?" He asked.
Kuu remained silent for a few moments then smiled slyly. Trunks wasn't a hundred percent sure he liked that smile. He just knew it wasn't going to be good for him. She swam further away from him. He stood right where he was not sure if she planned on splashing him or not.
"Get in with me and I'll tell you everything." She said.
He was taken aback by her demand. How old is she? She can't be much older than me. He began to walk closer to the shore; she swam farther away from him. Trunks began taken his shoes off. Trunks looked up, Goten was hover a few feet above. He floated down landing next to Trunks.
"Well we were right; it was Dad's energy we sensed, technically. Shenron says her name is Kuu. She's a part of my dad, and the four star Dragon ball." Goten explained.
"Wait, What?" Trunks asked.
"Aw you're no fun. I guess I was done swimming." Kuu said swimming back to the shore. The two half saiyans closed their eyes as she stepped out of the water. She scanned the around looking for her cheongsam. It laid wrinkled behind Trunks.
"Can you hand me my dress? It's just behind you."
They both turned around looking for her clothing. Trunks reached down grabbing it then handed it back to her with his back still turned to her.
"I guess I should explain everything to you." Kuu said shimmying her cheongsam on. "My name is Kuu. The Heart of Goku."
