Cardiac Arrest (Ereri/Riren AU) (Death Note AU) (L!Levi x Kira!Eren) (COMPLETED)

Face Off

 Eren

I sipped absently at my Starbucks coffee as Levi sat next to me, drinking tea. I took the drink away from my mouth, eyeing it, extremely confused.

"What's wrong?" Levi asked, cocking his head and moving his attention from his tea to me.

"This coffee. It's what I always get," I shook my head, "How?"

"Watari bought it, not me." The raven shrugged.

"You can call me Xel."

I turned around instantly to be met with a girl who was my age, a bored expression playing on her features. Her hair flowed past her mid back, a deep magenta color that brought out the brown of her eyes. She was wearing a shirt that showcased her tattoos, a collarbone tattoo that had flowing music notes, and a treble clef on her left forearm.

"How did you know what coffee to get me, Xel?" I asked.

"You're the same Eren as always, deep down," she replied, sitting on the couch in front of us.

"I don't understand how you know so much about us when we don't tell you anything, Xel." Levi admitted, looking at the female with expecting eyes.

She sat, legs crossed into her as she sighed, leaning back, "Do you really want to know, Levi, Eren?"

Levi nodded briskly, "I do, I don't know about him though."

I nodded, motioning for her to continue.

"Do you know of the multiverse theory?" Xel asked.

"Yeah, it's kind of like reincarnation, but it's us in different dimensions, right?" The older male replied, seeking confirmation.

She shook her head, "Not exactly. Basically, the theory says that there are multiple universes, not just this existence, occurring all at once. In these universes, different, sometimes similar realities occur. You may not believe me, but I've been to a few of them besides my own and in these universes, I knew you two."

I stayed silent, looking over to Levi.

"So the two of us were close in those other universes?" He cocked his head, "... What was our relationship like?"

She sighed, pulling out a bunch of polaroid photos as proof, "In this one, you two were musicians that were of total different backgrounds. Levi, you were about the age you are here, but you were the lead singer and backing guitarist for the band known as the Survey Corps. You held a competition where musicians could submit music and whoever won got to meet you and your band. Eren won this competition. This verse was very different from where we are now. Levi, you were in the band with Hange, Erwin was your manager, and Mike was also in your band."

"Hange and Erwin were what?" I asked, only believing things due to the pictures.

Xel ignored my comment, focusing on answering what Levi had inquired, "You two were very close. I mean, Eren literally took a bullet for you. You two are married and have a daughter."

"Married?!" Levi's voice showed his surprise more than his face did, despite his mouth being open in shock. "Eren and I are married?!"

She nodded, pushing two photographs towards me from across the coffee table. My eyes widened at the polaroid film. One picture was of Levi laying in bed with me, well, a different me in a hospital. I looked to be asleep while Levi kissed the top of my head. Another picture was of Levi, a girl, and I sitting around in a half circle, playing peekaboo. I looked closer at the handwriting on it, widening when I saw the name 'Luna'.

Levi grabbed the pictures from me, staring at them in amazement. He looked like a deer in headlights, unable to do anything but study the photographs in silence. He traced over the word 'Luna' with a finger, mumbling something about how it was unmistakably his writing. Opening and closing his mouth, speechless, the raven turned to me to check my reaction.
