A/N: Interesting. I thought it would be difficult to write this final story because it's connected with the light novels while having its own plot, but I'm on a roll :)

Thanks to ShadowFire10, Subtility, and goddessofshadows7212 for the faves/follows.

"Tsuchimikado Motoharu and I can use magic for thirty minutes," Celeste said.

He felt a strange wave wash over him, then the tingling disappeared. He expected to feel something. Perhaps some divine sign that he could now use magic. But he felt no different. He raised an eyebrow at her.

"Well? Start!" She ordered, fluttering her hands at him, before settling back to watch.

Tsuchimikado really hoped that her ability worked, and he really could use magic. Otherwise undoing all the spells would really hurt. Maybe even kill him. His lips twitched into a grimace as he turned back to the grimoire, studying the spells set on it. She was right. It was undoubtedly real, considering the strong magic radiating from the book itself, even under the many layers of barriers and protective spells.

"Fallere825," he murmured, and set to work.

It took exactly five minutes, just as he predicted. Tearing down so many spells took quite a bit of time and energy, and he had worked as quickly as he could. Therefore, he found himself in nearly the same state as Celeste had been when she transported them both to England, except with more energy remaining. He also doubted that he looked as much like a corpse as she had.

But still, he felt exhilarated at having been able to use magic without feeling any of the consequences. He had grown used to pain and physical damage whenever he used a spell, even the simplest ones, and to be able to feel the tingling of power without such repercussions… Well, it was astounding, to say the least.

But the feeling of euphoria didn't last long.

All the spells on the book were gone, and he had used magic without consequences, but in return, a group of magicians were pounding on the locked library door.

Tsuchimikado groaned, grimoire in his hand, heart thudding in his chest. He did not like this. Not at all.

She grinned.

He groaned once again.

And she kicked open the door, but not before grabbing his hand. Her hand was strangely warm. He had almost expected it to be icy cold, like a ghost or a corpse.

"Septu, warrior god, god of protection. I bow to thee. Let none touch us. Let all who try be destroyed by thy powers. I am Heredis000, defender, thou art our shield!" She shouted as she began shoving through the crowd.

He just knew all the magicians in St George's Cathedral were there.

It was official. Celeste Crowley, Aleister Crowley, and anyone who associated with them for enough time was insane. To think that if he had never met her, if he hadn't decided to face her or to follow her, he could be sitting at home with his dear little sister, watching television and munching comfortably on snacks.

Instead he was running for his life through a crowd of murderous magicians, all of whom were shouting out their magic names.

"Apollo, I invoke thee, bend light and hide our image, let us appear as what we are not," Celeste said as she ran, dragging Tsuchimikado behind her. "Ye lord Kalki, destroyer of darkness and foulness, destroyer of ignorance. I seize the darkness of the Church and bring it to your hands. Let the white horse come forth, let them face your wrath!"

In spite of himself, Tsuchimikado found himself intrigued. He had never heard the incantations she used, never thought someone could use so many types of magic at once. But he could trust her, at least, as long as they were partners. He was depending on her to protect him, after all, just as she depended on him to get the book, even though he had the niggling feeling that she could have done fine on her own.

He watched as the magicians milled around in confusion, looking straight over their heads, looking straight through them. It was like they had become invisible. And then the screams began. Magic users around them clutched at their heads, doubled over with pain. Only few remained upright, confused. Amongst them were Kanzaki and Stiyl. Tsuchimikado couldn't help but smile. At least his friends weren't hurt.

And then he turned back towards Celeste, and concentrated on running.

It felt like a miracle when they escaped the cathedral, unscratched and not pursued. Tsuchimikado could not help glancing back at the doors as they slammed shut behind them, wondering how and why in the world they had managed to lose an entire church full of angry magicians.

Somehow, the teenage girl named Celeste Crowley, despite being the same age as him, seemed much more deadly than anyone he had ever met. And that included Accelerator and Laura Stewart, the archbishop. If she ever wanted to destroy the Church or destroy Academy City, she could probably do it, and with ease. He shuddered. He should be glad, then, that she cared about Accelerator and Aleister too much to go against the science side, and that she had no grudges against the magic side.

But she would obey Aleister if he told her to destroy the Church.

Was that why she was summoning Lucifer? No, she probably didn't know that much. Aleister used his pawns without divulging any more information than necessary, and even though she was closer to him than his other pawns, Tsuchimikado doubted that she knew everything.

"Are we safe?" Tsuchimikado finally asked, hesitant.

"Probably," Celeste replied, and stopped.

The two stood there for a moment, catching their breath, a faint sheen of sweat on their skins. And then Celeste held her hand out for the grimoire. Tsuchimikado eyed her from behind his sunglasses and hesitated. He only paused for a second. Although normal people wouldn't notice, she undoubtedly did. And she smiled wryly, curling her fingers in a gesture for him to hand it over immediately.

He didn't comment. He simply put the book in her hand. Her attention immediately turned away from him, focusing on the book she was flipping through. Tsuchimikado contemplated tearing the grimoire from her hand and running, but he wouldn't get far. Not from her, at least. He could still use magic—around eleven or twelve minutes remained of the thirty—but she could as well. And he had no doubt that she knew more spells than he did.

One of the perks of training under Aleister Crowley, one of the greatest magicians that ever lived.

For a moment, he wondered just how much magic she knew. She was a level five esper. The news that spread like wildfire around Academy City and the world told him that much. And she could warp reality on top of that, a rare one of a kind power. Did she stop learning magic when she became an esper? He doubted that. She knew too much to have done so. But to learn magic while being an esper… It was a risk. Yet, somehow she didn't seem like a person who would shy away from any risk. After all, she was stupid enough to be an esper who would use large, complex magic to summon Lucifer.

Celeste sighed. "Moonless night, large magic circle, yada yada yada."

Tsuchimikado raised an eyebrow, bemused. People would kill to find out how to summon Lucifer, and here she was, treating it like the most mundane, troublesome thing. He supposed it would be, considering all the things you had to do to summon an angel-like being, whether it be an AIM entity or a fallen angel, or even one of the archangels.

And they had six days to prepare.
