Omake: Karp-Karp to the Rescue!
It's night time at the special koi fish pond. Karp-Karp is swimming around and terrorizing the smaller fish as he usually does. The household is sleeping after Hinata's big day. They were celebrating the day she was born.
Karp-Karp doesn't understand what the big deal is with making a big fuss over the day you hatched. Mother told him it's because trainers like to throw a celebration over anything. Mostly, trainers love free food. They can lure large gatherings of trainers and battle them for something called 'money.' Using this 'money', they can buy food. They're not very good hunters.
Karp-Karp plays under the bridge when he hears his weird trainer's whimpers. (Well not his trainer, yet. For some strange reason, she won't catch him. She plays with the pokeball like a toy.)
Karp-Karp is alarmed. As a Pokemon, he can feel the emotions of whichever human he's bonded with. He can feel his trainer's tremendous fear. Something terrible is happening to her. Determination fills the Magikarp. He uses Splash to hop his way to walls encasing the human dwelling. His instincts tell him she's outside the wall.
The three week old Magikarp uses its move Bounce to get over the wall. He drops to the grass below. He flops to where he feels Hinata's fear is coming from.
He sees an adult human sneaking away from his trainer's human dwelling. On his shoulder is a rope bound and crying Hinata. A silk scarf wrapped around her mouth muffles her cries.
Karp-Karp is furious! He won't allow the evil human to steal his trainer. She's his human. If he was a Gyarados, he would tear him to shreds. Mother always told him to never attack humans. They're too weak to handle the power of Pokemon. The only exception is evil humans, like Team Flare.
He uses a couple of splashes to catch up to him. He readies the most powerful bounce he can and launches to the air. He drops down on the evil human's back. "KAAAAARRRRP!"
The evil human, caught off guard, drops to the ground. Karp-Karp doesn't let up his attack. He continues with a barrage of Splash. He hops all over the evil human's back. Luckily, his bounce paralyzed him. He can tell from the twitches of his fingers.
"Kaaarrp Karp Karp Kaarp Magi Karrrp!" He smacks the evil human's head for good measure. His furious shrieks attract the girl's family.
A scurrying of feet brings the investigating Hyuuga to a halt. Hiashi, the one leading the party, displays open shock. Hinata is tied up, a shinobi (the kidnapper) is getting assaulted…by a screeching fish. Maybe he shouldn't have drunken sake at his first born's party.
