Author's Note: Ok this is my first ever crossover. I used to watch this anime when I was little and I realized that I could probably do a crossover since... well I don't actually know why but I figured I could so I'm gonna try my best.

"Kissa, Luchia, Hanon, Rina!" a voice yelled.

The 4 of us turned around to see my brother Kaito running toward us holding a flyer.

"Onii-San what's wrong?" I asked

"Nothings wrong little sister. In fact if anything everything going amazing!" Kaito said and Luchia gave him a kiss on the cheek.

"Then what has you so excited Kaito-kun?" Hanon asked getting quite excited herself.

"There's a surfing contest being held in Domino City and it features all the best surfers from around the world! Some major company's doing it for publicity but who cares I get to surf!" Kaito said.

"That great Kaito!" Luchia said jumping up and down.

"Onii-San can we come too?" I asked.

"Totally I got enough tickets for everyone to go. You, Luchia, Hanon, Rina, Karen, Noelle, Coco, Seira, Nagisa, Masahiro, Sara and Gaito!" Kaito managed to say before he was interrupted by our screaming.

"Arigato Kaito-kun." Rina thanked managing to suppress her excitement.

Kaito nodded as Luchia pulled him out of the kitchen and into the staff room where everyone else was. Poor Nii-san having to explain everything again. I followed a few minutes later only to here Hippo start talking.

"Kaito-kun we told the mermaids of the Red Sea, the sea your little sister rules over shall I remind you, that we will be visiting them for a few weeks."

"Jeez Hippo I'll tell them there's been a change of plans." I cut in.

"So its settled then we leave tomorrow for 2 months. Yup we're there for the entire summer!" Kaito pumped his fist in the air. Everyone did the same except for Hippo who just shook his head.

*Next Day*

"Ouch!" I cried out falling down the stairs.

"Kissa be more careful." Gaito said

"Sorry Nii-sama but I can't wait to go!" I squealed has Gaito helped me pick up somethings that fell out of my purse.

"Stop acting like a child, you're 18 Kissa." Nii-sama laughed.

I stuck out my lower lip "I know but I've been so busy ruling over the Red Sea I just haven't had time for a vacation so this is a dream come true."

"Now now Kissa don't start pouting."

I giggled as Nii-sama made a face at me. Once everything was picked up he helped me up. All of a sudden Coco came running down the stairs, just like me she fell. Coco was soon followed by Luchia who landed on her, as the two got themselves organized Gaito shook his head and grabbed led me to the bus Nikora-San had rented. Gaito carried all my bags leaving me only holding my white purse that shimmered blue when hit by the light in a certain way, much like my shoulder length hair. In human form I enjoy cutting my hair so that it pasted my shoulders by about an inch, much like the length of Luchia's hair, but it doesn't go out to the sides. Of course in mermaid form my hair only reached to my lower back. My hair was wavy but a little straight too, my bangs covered my eyebrows but narrowly missed my blue eyes, they fell where every the seemed to want. Nikora-San has always told me to arrange them nicely but I never listen to her. I sat beside Hanon since Nagisa said he would meet us at the airport with Masahiro and Nii-san. The entire time we talked and made fun of Luchia who got mad and stopped talking to us for a while, halfway through the ride we got bored so we started singing Hanon's song.

At the end we started laughing.

"You know Kissa-chan you sing that song really well." Hanon complimented

I blushed "Not as good as you, I've only been singing for 2 years since I was kept in the dark about my true identity until you girls found me in Egypt."

Hanon smiled "Yup and that was one amazing day. I mean figuring out that there's a 9th Mermaid Princess! Who would have thought? Also the fact that the 9th Princess was the younger sister of Kaito-kun and Gaito-sama. Amazing!"

My blush deepened "Wahh Hanon you're so nice."

Hanon smirked and Rina asked her a question, soon the two of them were deep in conversation. I looked out the window, I hope I can see that boy from the orphanage again. I hoped. The one part of my past nobody knew aside from the people in the orphanage and me. In that place everyone made fun of me except for 2 people, Seto and Mokuba, they were brothers even though they looked nothing alike. Maybe just maybe they still lived in Domino City, the chance was slim but I'll hold onto the little piece of hope I have until I'm proven wrong.

"Alright we're here." Nikora-san yelled out stopping the bus.

We all piled out and grabbed our bags. We ran through the check up and everything quite fast and we managed to get on the plane 1 hour later. I waved goodbye to Nikora-san as we got on the plane, the second we left the ground I fell asleep, after all I'll need all my energy just to keep up with Kaito's excitement about the surfing contest.
