Disclaimer: I don't own any one of this characters but this is my plot.

Deuce's POV

Cleo and I were franticly searching the hallways for Sirena.

"How can Sirena help?" Cleo said

"Her sister goes to the same school as Cupid." I replied

"What? How do you know that?"

"She's my niece, well half-niece but whatever."

"Oh My Ra, she's your niece. How is that possible she's a mermaid/ghost and you're a gorgon?"

"Long story, but right now we just need to find Sirena."

We turned the hall and I saw Avea, Neighthan, Bonita, and Sirena standing by their lockers, talking to each other. I ran over to them and said:

"Sirena, we need your help!"

"You need my help; with what?" Sirena said

"Your sister's school is in danger and we need your help to get there."

"What, my sister's is trouble, follow me?!" Sirena replied

Sirena started floating away quickly determined to save her sister

"Sirena the exit is the other way." Avea said

Sirena turned around and started floating the other way and replied "I knew that."

Cleo, Neighthan, Bonita, Avea, and I followed behind Sirena to the exit.

"Sirena, where do we need to go?" I said

"Mt. Oympus." She replied

"Mt. Olympus, that's perfect. I just hope my dad isn't there."

"Your dad lives on Mt. Olympus?" Cleo Asked

"I'll explain later." I said

"Sorry to interrupt but were at school; we just can't leave." Bonita said while chewing on her sleeves

"Your right, someone needs to go tell Headmistress Bloodgood about the situation and everyone needs to call their parents." I replied

"I'll go tell Headmistress Bloodgood." Said Neighthan

He started running down the hallway and tripped. He looked back and said

"I'm Okay!" and started running back down the hallway."

Cleo looked at me and asked "What's the plan?"

"Don't worry you'll see."

Everyone got their phones out to call their parents, but I was going to call someone else.

Meanwhile in Mount Olympus

There were two girls both sitting on a bed. One had blue skin, plumb hair with green streaks, and had a mermaid like tail made out of algae and her name was Posea Reef, Daughter of Poseidon. The other one had blue skin as well, pink hair with purple lighting strike streaks, wearing a magenta top and a light pink shirt and she was named Zori Weatherbolt, Daughter of Zeus, The King of The Gods.

"Would you rather marry a mortal or a god?" Zori said

"Um…," Then Posea's phone started ringing and she picked it up to see who was calling. "Hold on its Deuce."

"Hey, what's up brother from another mother?"

"Posea can you open portals to other dimensions?" I said

"No, but dad can, I can get him if you me too."

"Please don't, can you open a portal to Mt. Olympus and don't let the other gods know expect Eros?"

"Yes, I can but can I tell Zori?"

"Yes, of course, please hurry up it's an emergency!"

"Okay, I'm on it."

Back at Monster High

Deuce's POV

I hang up the phone and said "Okay, follow me, let's go to the pool."

"Deuce why are we swimming, you said it was an emergency." Cleo Asked

"We aren't swimming it's our way to get to Mt. Olympus." I said

"What about Neighthan, he's not back yet?" Avea said

"You can go get him and we'll go to the pool." I said

Avea quickly trotted off to Headmistress Bloodgood's office.

"Okay, everyone else that's go!" I said

So we all quickly went down the halls and went outside to the school pool. I saw that the portal had formed.

"Deuce isn't that the same portal that our friends were sucked into." Cleo said

"Yeah, it is. But don't worry its safe." D

"How do you know's it safe?" Cleo asked

I looked Cleo and asked "Do you trust me?"

"Of course I do." Cleo replied unsure of herself

I heard the sound of horse hooves and turned around to see Neighthan riding on Avea who was trotting back to get to the portal.

Bonita looked confused, looked at Avea, and said "Since when do you let people ride you?"

"Neighthan kept tripping and I got impatient." Avea said

"Are you ready?" Deuce said

Everyone nodded expect Sirena; who was looking at a beetle.

"Sirena, are you ready." Said Neighthan

"Oh, I get to go in the portal first!"

Sirena started swimming into the portal and said "WEEEEEE! This is so fun!" and Avea rolled her eyes

After everyone jumped in the portal expect Cleo and I; I grabbed Cleo's hand looked at her and said "Are you ready?"

She nodded and then we both jumped in.

I was underwater still holding Cleo's hand, trying to swim to the top. We reached the top and we both gasped for air. We made it to Mt. Olympus. Everyone else already got out of pool and I saw Eros, Posea, and Zori introducing themselves to the hybrids. Well of course Sirena already knew Posea, she was her aunt.

We got out of the pool and looked over at Posea and Zori said "What's up Posea and Zori?"

At the same time; Zori said "Nothing much." and Posea said "Deuce!"

Posea ran up to me and gave me hug. She stopped hugging me and said "Its nice to see you; what's the emergency?"

I looked at Eros and said "Cupid's school is in trouble."

Eros looked nervous as heck and said "Oh no, quickly follow me!"

Eros leaded everyone down a long hallway, and I was about to follow them but Zori grabbed my arm.

"Deuce, I know you don't trust your father right now, but my dad can help."

"No offense Zori, but I don't trust Zeus around mortals."

"Okay, that's a good point. Let's just go."

We caught up with the others and continued down the hallway; at the end of the hallway was a mirror.

"Here it is, just step right in." Said Eros

I looked in the mirror and my appearance completely changed, I stepped in, and when I come out I saw…..
