A/N: Sorry I haven't updated in a while, another of my stories suddenly gained a bit of popularity, so I was working on it instead! Yah, lame excuse, I know… On another note, when Rin is singing I will bold it instead of using ""s. With Len I'll underline, and with both, I will use both. That sounded funny :D

"Shh… It's okay, those mean twins won't hurt you any more. I'll protect you, so calm down. It'll be alright." Rin cooed. She was softly petting the small, dark bat as it trembled in fright.

"I got it." Rin said softly. "How about a song? I heard somewhere that frightened animals react well to that." The bat's only response was to bury its head into her shirt. Rin chuckled. "I'll take that as a yes." She thought a moment, attempting to pick the perfect song. It couldn't be too fast, or with too many high notes, that might frighten the poor creature.

'I've got it!'

Daijoubu, daijoubu. Odokete miseru boku wa…

"Sister, dear, the next time you want bat food you can go pick it up yourself! It's a whole freakin' hour to the pet store, and I'm not doing that again…" Len muttered unhappily. He opened the door to their dorm room slowly, knowing that if he upset their 'little guest' Rin would make sure he paid for it dearly.

Chiisana saakasu no, na mo naki piero…

'If that's not Pierrot, I'm not Len Kagamine. Maybe I'll 'help her out' with the next line.' he thought.

Manmarui otsukisama mitai na…

Hearing her twin, Rin looked up in surprise. Len grinned and she nodded, signaling for him to continue.

Booru no ue baransu o totte…

They kept switching back and forth in perfect harmony, the way only twins could, creating a beautiful melody. Before either of them realized it, the bat Rin had been trying to comfort was asleep and the song had ended. Len opened his mouth to say something, but Rin clapped a hand over his mouth. She gently placed the bat on their bed and dragged Len into the hallway.

"What is it, brother?"

"I got you bat food, sister."

Rin sighed in annoyance. "You know, you could just say bugs. Better yet, how about a 'Hello, sister!' for once?"

Len gritted his teeth. "Hello, sister dear. Now can I ask you something?"

"You just did."

"You know what I mean!"

"Fine, shoot away."

"Where'd you get the bat?"

"Those other twins were nice enough to dump around twenty of them in our room. I opened the window to let them out before the hurt themselves, but it was too late for that one. His left wing is damaged, a little rip in the webbing near the middle."

"When will he be gone?"

Rin smacked her twin on the head with a book she pulled out of nowhere, screaming "Rin-chan CHOP!"

Len fell on his butt, holding his head. "Owowow… What was that for?"

Rin giggled cheerfully. "Saw it on TV. I think they called it a 'Maka chop'. This brunette was always hitting people over the head with books, and I wanted to try it. Also, DON'T ACT LIKE YOU CAN'T WAIT TO GET RID OF LAUREN!"

"Lauren?" he asked.

"The bat, stupid! Honestly, you are so dense sometimes…"

"Sorry, sister, if you didn't make it extremely obvious."

"It's okay, just tell the twins we appreciate the pet they gave us."

Len grinned mischievously. "And may I give them a…present in return?"

Rin jumped up and down, clapping her hands. "Ooh, yes! And you should give it a cute little collar! Write a little thank-you note and tie it to the collar! It's perfect! Just make it polite, I absolutely adore their 'gift'!"

"Will do, sister."

"You know, if you keep acting like the servant of evil you're gonna die."

A/N: So how do you like the Kagamine's new pet? Should I have made it a snake instead? What do you guys think they should give the Hitachiin twins? I need feedback, people!
