Hiragi Shinoa smiled as she entered her classroom one particular afternoon after school and saw that her friends were already there. She had arrived a bit later than the time she had set for everyone else because she was then sure they would be there.

"You're late," Hyakuya Yuichirou said with an irritated look. The smile Shinoa was wearing didn't please him much.

"I intentionally set your time earlier than mine," she said.

"You intentionally did?" Yuu stood up and glared at the short girl.

"Yu-kun, calm down," Saotome Yoichi tried to stop his friend.

"So what is this about anyway?" Hyakuya Mikaela asked, only now looking up at the leader of their club.

This group of people actually did have a club, yes. It was a club where they were somewhat role playing with some cards in addition. These cards were their weapons. Among these were some rare weapon-cards called the Black Demon Series out of the six members of this club, only Yuu, Yoichi and Kimizuki Shihou had gotten their hands on one. It was nothing really official and therefore this group of high school kids could hardly be recognized as a club, but because Shinoa was the chairman's daughter they were actually accepted as one.

"Well it isn't really club-related, and yet it still is," Shinoa grabbed a chair and sat down on it, still with a smile on her face as she met her club members' eyes. "I have been chatting with a friend online from a town not too far away from here. She is the manager of a club at her school and I asked if we could challenge her club and she just answered yes," Shinoa said.

"When is it?" Sanguu Mitsuba asked.

Shinoa looked thoughtful. "This Saturday," she said.

"I have to decline," Mitsuba said as a response. "There's a family gathering on that day,"

Shinoa nodded. "That's a shame," she said, not really sounding like it was. "What about the rest of you?" She started off by sending Yoichi an intense look.

"uh… I don't think I have any plans," he said.

"I don't have anything either," Kimizuki said before Shinoa's gaze even got the time to trail to him.

Shinoa's gaze then moved to Yuu and Mika.

"If I'm not going, you're just gonna drag me along anyway," Yuu said in a grumpy tone. "So I'll go,"

"What do you mean I'll drag you?" Shinoa asked in a sugar-sweet tone making it only painfully obvious it had been her intention exactly.

"If Yuu-chan goes, then I'll go too," Mika said.

Shinoa pulled out her cellphone. "I'll tell her that then, we'll be five people coming," she said.

"Hold on," Yuu said. "What is this thing anyway?"

Shinoa smiled secretively. "You'll see once we arrive on Saturday. Be at the station at 6 in the morning, all I can tell you is that you should probably bring something to swim in, and lunch," Shinoa said the last after a quick break to think. "I doubt they'll make anything for us," Then she got off the chair. "I'll see you on Saturday," she said and exited the classroom again.

As the door closed behind the small girl, all the boys exchanged looks. Mitsuba was the only one smiling, seeing as she had an excuse not to go with them, wherever they were going. She would admit that she was looking forward to see them on Monday though, and hear what hell their leader had pulled them through.

At 6 on a Saturday morning when everyone else from their class were sleeping in like any normal teen would do, Kimizuki, Yoichi, Yu, Mika and Shinoa were all gathered on the station, prepared to go to where in the world Shinoa was going to take them. There wasn't a single one of the boys who weren't just a tiny bit more grumpy than usual. None of them liked the idea of having to get up way too early in the morning. Shinoa was the only one seeming overly happy about the whole situation.

"Did you pack everything I told you to?" she asked the boys who each had a bag over their shoulder. Shinoa held a much smaller bag over hers.

"Why won't we?" Yuu asked. "None of us want to risk being soaking wet or worse," he continued.

"Well, the train should be here in a few minutes, we better prepare ourselves," Shinoa said.

As if on cue the train rolled up and the four boys and the girl boarded quickly. Since the station they got on from was small, the train had no reason to stay too long and as soon as Yoichi had boarded as the last one, the doors closed and the train left the station.

After traveling for a couple of hours the train finally arrived at their destination, Iwatobi Station. They had had to change train once to a more local line because this town was way smaller than where they came from.

Shinoa looked around once the train left the station. "She should be somewhere around here," she mumbled while continuing to look.

A girl walked up to them with a bright smile on her face. "Are you Hiragi Shinoa-san?" she asked.

"I am," Shinoa said. "Matsuoka… was it Gou or Kou you would rather be called?" Shinoa asked, trenching out her hand. The other girl took it and shook it.

"Kou please," she said, politely. She was taller than Shinoa, more on the boys' level of height actually.

"Are we doing introductions now or later?" Shinoa asked.

Kou looked thoughtful for a bit. "Later, then your friends only have to do it once," was the answer. "Well, we should get going," she started leading the way, away from the station to wherever they were supposed to be at.

The distance wasn't far. They had only been walking for around 5 minutes before they saw a sign saying 'Iwatobi High School'. Kou led them in the direction of a room where she instructed the boys to change. She let Shinoa elsewhere.

"Wait," Yuu called out to the other girl. "What are we supposed to wear?" he asked.

Kou looked at Shinoa who looked back at Kou, then the other girl nodded, understanding and answered. "Shinoa-san told you to bring swimsuits didn't she?" she asked.

"Eh…" Yuu didn't know what to say to that.

"Just change, moron," Kimizuki said as he started getting himself undressed. Yoichi and Mika quickly followed and Yu caught on as the last one and started changing as well, while Kou closed the door, leaving them alone.

"So it's some water-related sport?" Yuu said as he pulled on his swimming trunks.

"You only just figured out, Yuu-chan?" Mika asked, he was already finished with changing and watching as Yuu finished changing as well. Yoichi and Kimizuki were also only waiting for their not-so-smart friend to finish.

"So what?" Yuu asked.

Mika let out a soft laughter. "It's just like you," he said.

"Would you finish already?" Kimizuki asked.

"Yeah, yeah, don't rush," Yuu mumbled while finishing.

"Then don't be so slow,"

"Hey, stop," Yoichi stepped in between Yuu and Kimizuki, knowing full well where this was going, the exact same way situations like this always went. Eventually Mika would side with Yuu and Yoichi would, when trying to stop them, get accused for siding with Kimizuki and then Yuu wouldn't talk to him the rest of the day. He had tried it before, so therefore he had learned to stop their fights before Mika could manage to side with Yuu.

"Not my fault you strip like you do it every day!" Yuu argued back, not hearing Yoichi's words.

"Yu-kun! Kimizuki-kun. Stop arguing!" Yoichi called to both of them. "Kou-san and Shinoa-san are both waiting for us, we should go," he said once the other two shut up for a second.

"Yoichi's right," Mika said, sensing the other's motive. "Let's get going, Yuu-chan," He then led the way out of the room and the other three followed, wondering what would be awaiting them at the pool, they could see close by.

Here we go, one of the most random crossovers in history has gotten started. My friend and I like both these series and therefore wondered how the characters would interact with each other. Of course, even if it doesn't say it in the summary, this is an AU on Owari no Seraph's part. I guess you could figure.

I hope someone will enjoy this story. It consists only of humor and randomness (Is that a genre?)

Also, I'm calling Gou by Kou for now, because that is what the boys from OnS believe she is called. It will be changed once/if they realize the truth.

I hope you have fun, don't forget to review, favorite and follow if you wish for this. See you tomorrow
