The Cosmos' Journey (Obey Me! x OC)

The Twins' Birthday Cruise

Just an average day at the House of Lamentation. Asmo chirped. "Okay, you two. Time for your blindfolds!"

Ivy shuddered. Belphie was confused. "Huh? What?"

Beel's head tilted. "What's going on? I hope you aren't planning anything weird."

Ivy hummed. "Put it on, Belphie. Please?"

Belphie fought with himself. "You can beg all you want, Ivy. I'm not doing it... (Ivy gives him a pleading look)... Ugh, fine. You know I can't say no when you look at me like that. But Beel has to put his on too."

Beel gave in. "... Fine."

-Timeskip-

Asmo piped up. "Okay, we're going to take the blindfolds off now. One... two... three!"

Ivy removed Beel's with some help from getting on Asmo's shoulders. Asmo let her down as he spoke. "Well? Isn't it fabulous?! It's just perfect for me! A gorgeous, luxury cruise ship!"

Ivy smacked him over the head with her chancla. Levi sighed. "This isn't for you, Asmo, remember...? We prepared this for Beel and Belphie."

Asmo cradled his head after the attack. Beel just stared. "It's massive... and looks so tasty..."

Belphie turned to his twin. "No eating the ship, Beel. You'll sink it."

"Okay. I'll try my best."

"... This is for us? Does that mean you...?"

Ivy smiled and walked ahead. Asmo beckoned to them. "Come on. Everyone's waiting for you 💖"

-Timeskip-

Ivy skipped over to where the rest were waiting when they arrived. Diavolo smiled at the twins. "Finally, the honorary guests have arrived. Lucifer and I reserved this cruise ship as a birthday present for the two of you."

Lucifer smiled at them. "It's an overnight cruise. We thought you might like to celebrate your birthday a little differently this year."

Beel blinked. "It's amazing."

Belphie nodded. "Yeah..."

Mammon grinned. "Whoa, it's huge in here! There's a casino, ya know?!"

Mammon faltered when Ivy smacked him with the chancla. Satan only sighed. "Hopefully that'll keep Mammon entertained for the trip. It is incredibly spacious, though. Like it or not, you're going to be exploring the whole ship, so you can look forward to it."

Belphie turned to him. "'Like it or not'...?"

"This isn't the only surprise we have in store for you two."

Mammon rubbed his shoulder. "That's right. We've got some presents for ya, but we're not gonna hand 'em over just yet."

Satan turned to the only female. "Ivy, if you would be so kind..."

Ivy only shot him a winning smile. "Coming right up."

She handed the two letters. Beel looked it over. "... A letter?"

Belphie looked over his. "'Collect all the star fragments. Gather enough to summon a star shower'...?"

"Mine says... 'Search for the key. Something tasty is waiting for you'...? I've got to start looking for that key."

"Nothing can ever be simple with you guys. Fine, I'll play along."

A few minutes later, Ivy walked in between the twins. Belphie turned to her. "I was told to bring you along on my search... but I don't even know where to begin."
