"Hey, look at this." Sam told his brother. Dean just woke up and grabbed a coffee and a beer. He walked over to Sam's computer.

"What is it?"

"Five people from Yander High School have mysteriously vanished this last month. Before they vanished, they all became obsessed with the same Animes and other TV shows."

"And it's only thirty minutes from here. Sounds like a case, I'll go get Cass."

Sam jumped up. "I'll get Cass; you can find directions to Silvia town."

Dean watched as Sam walked to get Cass. After Sam left, Dean lifted up his sleeve and looked at the mark of Cain.

"Hey Cass, we're going on a hunting trip. You should come with us."

"You want me to keep an eye on Dean." Cass said.

"He's been getting worse"

Cass followed Sam out to the Impala

"Let's go find our Anime killer." Dean said as he stepped on the gas pedal.

"I'm Detective Bob and this is my partner Detective Marley, we're looking into the missing kids that use to go to this high school, Can we have their names and addresses?"

"Yes, detectives. Let me just print it out for you." The principal said as she started typing

Cass was walking around the high school. The teenage girl from earlier caught his attention by asking "Who are you?"

"I am Castiel," Then he remembered that he was 'FBI', "Agent Castiel."

She smiled "It's Christmas!" She exclaimed.

"No it's February 26th. My half brothers birthday was two months and one day ago."

The teen age girl smiled even wider. "Cass, come here. I have information on the missing person's case."

"How do you know we're on a missing per-" Cass started to ask, but the girl started kissing him. As she did this, his pupils dilated.

She pulled from his lips, as he stood, under a trance. "Hello Castiel. Ever since I read the supernatural books, I knew that I had to find you. My mom was a witch so I knew it was all real. When Mom passed away, I got her books, and her powers. I'm inside your head," the fourteen year old said as she put her hands on Cass's head, "and I can make Destiel real. You love Dean."

"I love Dean." Cass repeated.

"You love Dean more than anything. More than life. Your love for him out ways any pain. Your-"

"Hey Cass, where'd you go?" Sam's voice echoed through the school hall.

" ĦaþiscæşŞ" She chanted and vanished.

Just as she did, Sam turned the corner. "There you are, find anything?"

Castiel looked at Sam, his pupils undilated. "No. Where's Dean?"

"Still with the principle. After we get the list, you two stay here and check this place out more. I'll be checking up with the kids' families," Sam said, "And make sure Dean doesn't hurt anyone."

"Sam, is it just me, or was the principal hot." Dean said as he walked up, handing Sam the paper.

"Just you." Sam replied as he grabbed the paper and left.

"If you hurt my Impala I swear I'll kill you." Dean yelled at his brother. Dean turned to look at Cass, who is smiling at the sight of the oldest Winchester. "What are you smiling about?"

"Dean, you're such a divine piece of beauty." Cass said, smiling wider.

"What?"

Cass's face started turning red, Dean watched confused and concerned. "I love you Dean-Senpai."

Dean brought out an angel blade. "You're not Cass."

Sam walks out to the Impala and pats his pocket. He sighs, "Dean still has the keys." Sam started heading back to Dean and Castiel.

"What have you done with Cass!" Dean askes as he has the angel blade to Castiel's neck.

"I'm still Castiel my Senpia." Cass said smiling. He tried to kiss Dean.

In response to the attempted kiss, Dean sliced the angel blade across his face. The angel winced at the pain for a second as his face glowed from the blade, but smiled and blushed, making more blood come out of his wound. "I love you Dean!" Castiel proclaimed. Dean cut his face again with no change in Cass's reaction.

"What did you do to Castiel!" Dean yelled.

"I'll do anything you want me to do my love! I love you more than life itself!"

This time Dean cut his arm. It got a slightly longer wince, but still followed by a smile and longing gaze into Deans eyes.

"Tell me where the real Cass is or the next cut will be off with your head." Dean threatened with the angel blade at his neck again. Cass smiled.

"Hey Dean, it's hard to unlock a car without its… DEAN!." Sam said, and he ran to Dean and Cass. He pulled the angel blade out of Dean's hand.

"Sam, that's not Cass." Dean said.

"Dean, he could just be possessed. You're still hurting Castiel." Sam yelled at his brother. Cass watched in silence, his blue eyes dreamily staring at dean, still smiling.

Dean looked at Cass then at the floor. "I didn't really think of that."

Sam went to Cass. "Are you okay?" He asked him.

"I'm always wonderful if my Deanykins is near." Cass said.

Sam looked at his brother. "And he's been calling me 'Senpai'."

"What the hell is a Senpai?" Sam asked

"I don't know! He told me he loves me and tried to kiss me!"

Sam looked back at Cass. "Dean is my everything. He's so nice and sweet and beautiful. He's my senpai. Can we have your blessing once I marry him?"

"I'm going to call Crowley. Don't kill Cass!" Sam instructed Dean.

"I won't." Dean said looking the angel.

"Oh Senpai!" Cass yelled as he hugged Dean.

Sam watched Dean try to claw Cass off of him for a second then turned around to talk to the king of hell.

" 'Ellow Moose. Miss me already. You and your ex-demon brother are so needy." The British demon said.

"Crowley, come over here. Cass is acting very weird."

"No. I'm not your bloody slave! Solve your own damn problems for once!" Crowley yelled, hanging up.

"CROWLEY!" Sam yelled but Crowley already hung up. Sam turned to Dean and Cass, Cass was now kissing Dean as well as hugging him, the angel's strength outweighed the human's.

"Please help me," Dean said as Cass fondled his hair

"How? We have no idea what's wrong with him."

Cass licked Dean's face.

"Do anything!" Dean commanded.

"Hey Cass." Sam said

"Destiel for life." Cass responded.

"How about you and Dean go back to the Motel?"

Cass's eyes and smile widened. "I'll put my tie on the door for you, senpai"

"SAM!" Dean yelled as Cass started dragging him away.

"Cass, what about a movie instead?"

Cass stopped smiling. "Senpai wants to go back to the motel. If you have a problem with that, I could always eliminate you."

"Cass, I want to watch a movie, and don't you ever threaten my brother again." Dean said

Cass looked at Dean and smiled again. "Okay senpai. Let's go!" He puts his fingers on Dean's head and they disappear from the school.

"Dean!" Sam yelled into an empty hallway.
