A/N: Thanks Kira Minzu for favoriting and following!

"Shiro-chan, if I disappeared, if I stopped existing, will you miss me?"

Her phone rang once, twice, three times. And it fell silent once again. Celeste sighed, leaning her head back against the tree, eyes closed, trying to relax and concentrate.

Three hours left.

With her body this tense, it would be a long wait.

For the hundredth time, her eyes scanned the clearing, checking on her magic traps. They were all potent and ready.

Wasn't there anything else she could do to prepare? Even if Satori Miroku had been weak, his spell easy to shake off, there was no saying that the rest of them were the same level.

With her ability, some complex things took surprisingly little energy and required surprisingly little as an exchange, but some simple things took a surprising amount of energy.

And some things she didn't dare try because she had no idea what the consequences would be.

It would have been so easy just to kill someone with words, but exactly what would the universe demand in exchange?

A branch cracked.

Celeste shot to her feet, ready to fight.

But she froze in surprise, eyes widening when they met red and white. What…?

"Shi—"

"Titania," Accelerator growled.

He was furious. The idiot dared to disappear on him again! At least this time he had realized something was wrong. And he had used the Misaka network to hack into her phone signal. They tracked her down.

"H-how… Why…"

"They found the body, idiot."

"O-oh…" She averted her eyes. She couldn't look him straight in the eye. Not now.

Something in Accelerator snapped. "What the hell! You really think you could disappear again looking like you're going to die?! Fuck you!"

Her eyes widened, snapping back to meet his red orbs. That was the first time he had ever cussed her out like that. It only meant one thing. He was pissed. But…

"I won't die, okay? So you should leave. You shouldn't get involved in this," she said, giving him a smile.

Accelerator's eyes narrowed. It was another of those damned smiles that didn't reach her eyes. Did she really think she could deceive him with that pathetic attempt at a smile? Had she forgotten that he was the one who had seen more of her smiles than anybody else? Had she forgotten who she had spent the most time with?

If she thought he wouldn't see through her, she had another thought coming.

"No."

"H-huh?!" She stuttered, surprised.

"No. Or are you deaf?! Kusotare!" Accelerator snapped.

"B-but—"

"And stop stuttering! It's annoying and so not like you that I want to punch some sense back into that empty head of yours!"

Celeste opened her mouth, but shut it again immediately. She really didn't want him to see this. She wanted him to keep seeing her as the cheerful girl who wouldn't hurt anyone.

She didn't want him to become disgusted with her when he saw her massacre a bunch of people, didn't want him to develop an even lower opinion of her when he found out that she was considered 'cursed', an abomination.

"So what the hell was it that made you leave again?" Accelerator huffed.

"I…"

"Are there people you need to kill?"

Her head shot up, the girl's mind going blank in shock. Accelerator rolled his eyes at her reaction. It wasn't as if he didn't know she had other sides to her that he had never seen. Her attitude towards that Satori bastard was something he had never seen before. And it wouldn't surprise him if she had killed people before.

She had smelled faintly of blood and death the day she returned, the day she healed him.

He knew that scent very well.

"I know you've killed people before, idiot. So have I. So what? I've seen you pound someone into the dirt for insulting me when we were kids. It's not like I don't know how violent you could be."

Celeste blinked, mind wrapping around the words for a moment before her shoulders started to shake.

"Stop laughing, damn it!" Accelerator snapped, scowling.

"Sorry, sorry! I just… Really didn't expect you to try and comfort me," she giggled. "And you're not really that good at comforting people."

"Tch."

She poked his cheek, grinning. "You're cute when you pout."

"I'm not cute!"

"Yeah, keep telling yourself that. You'll always be my adorable tsundere," Celeste said, her tension completely gone.

He always had that effect on her.

"Your what?!" His face was red, heated from a mixture of anger and embarrassment. "I'm NOT a tsundere, idiot!"

She didn't reply, but her eyes were dancing in amusement.

"Tch," he repeated.

It was silent for a while, but it was comfortable. The two stood side by side, backs leaning against the tree, arms barely touching. Accelerator wondered when he had become so comfortable, so used to her presence. If anyone else dared touch him so casually, he would probably tear their heads off.

In fact he had killed several people simply for bumping into him when he was in a bad mood.

What? They didn't apologize, and they should have known better than to get too near the Accelerator.

It wasn't like he was hard to recognize, with the white hair and red eyes and all.

Interrupting the silence, her phone rang once.

Accelerator felt Celeste stiffen, then relax with a sigh. She had no idea how she missed the two hour mark, but with Accelerator distracting her, it wasn't surprising.

"They're here to kill onii-chan," Celeste finally said.

"You have a brother?" Accelerator asked, dumbfounded.

She gave a small smile. "He's more like my great great great times I don't know how many generations grandfather. But he looks too young, and it's a lot shorter to call him 'onii-chan'."

"People can't live that long…" Accelerator deadpanned. Then it hit him. Could it be?

"It's a secret, but it's Aleister Crowley. A founder of Academy City and one of the residents of the Windowless Building," she told him.

"Oh. That bastard."

She raised her eyebrow.

"He used me as a pawn."

"Yeah. I know."

At that, he shot her a glare. "What?"

"I read the files," she corrected. "They never really did anything until three years ago, right?"

Accelerator scowled. "He waited until you were gone."

"Yeah. At least he respects me that much."

Accelerator wondered if he should mention that he threw a building at her 'brother'.

But then again, if she was killing a whole bunch of people to protect the bastard, he didn't think she would take too well to finding out that he had tried to attack the man.

Briefly he wondered if she had to choose between them, who she would choose.

When he thought that it might be Aleister, something inside him clenched, and he felt like killing something. Namely Aleister.

"Well, well. We are honoured to have the Cursed Child come all the way out to meet us," a new voice said.

The two teens stiffened. They glared at the new arrivals.

Celeste made a low growl. "There's ten minutes to spare. So much for you bastards arriving in an hour."

"Tch. I dare you to try."
