Accelerator screamed with rage as he ran into yet another dead end. He had gone through several information networks, only to find nothing. He had even searched through the information banks from the newly destroyed dark side of Academy City, to no avail. There was no information on the Windowless Building, and no way in.
There had to be a way in and out, without using Celeste's ability. One could probably teleport in, but the Windowless Building's security would not be so lax if even a building and five minutes of Earth's rotation could not even scratch its surface. It couldn't be as simple as teleporting inside. Normal teleporters would not know how the place worked, and would get into a very painful and perhaps even life threatening accident. And that didn't include the traps that doubtlessly lay inside.
But that only meant normal teleporters could not get in. There had to be one or two who could, aside from Celeste. Because if all three people got wiped out, then there would be no way for Aleister Crowley to interact with the outside world, save for exiting the building himself.
Yomikawa peeked into the room and sighed. He had asked her about getting into the Windowless Building first, before going to Yoshikawa. Both of their answers were the same. They would look into it, but he shouldn't get his hopes up. And as Yomikawa expected, none of the Anti Skill databases contained any information about the Windowless Building, top secret data or not. Nobody could get in, basically.
Yoshikawa came up with the same conclusion. None of the research databases in the entire Academy City had any information. At the most, she had told Accelerator, the information was written on paper and hidden somewhere. But even that was highly unlikely. All the information was probably kept in certain trustworthy brains, only passed on to those deemed worthy of the knowledge.
Accelerator knew that meant the Misaka Network wouldn't know anything either, but it didn't stop him from trying. And just as everyone expected, they came up with zilch.
With Celeste in such a condition, there was nobody else he could ask. It wasn't like the databases actually stated that a person 'could get into the Windowless Building' or not. He would have to investigate the inhabitants of Academy City one by one. Or rather, he would have to investigate those who had been a part of the dark side of Academy City. Nobody in the light would have such knowledge.
Out of the people he knew, that left GROUP, Kamijou Touma, Misaka Mikoto, and Heaven Canceller. He could strike Imagine Breaker and Railgun off the list immediately. He highly doubted that Kamijou Touma knew the way in, considering that his right arm nullified any supernatural ability. That meant that he probably couldn't be teleported anywhere. As for Railgun, she hadn't learned about the dark side until very recently, and it took her a long time to discover the Level Six Project. If she wasn't in on things from the start, she wasn't deep enough in the dark side.
That left GROUP and Heaven Canceller.
Accelerator frowned, collapsing into a chair as he thought. If he were a less suspicious person, he would strike out Heaven Canceller and Tsuchimikado Motoharu. They had been in the hospital room with him when he practically declared war on Aleister Crowley, and they hadn't said anything.
Yet, the more he thought about it, the more it would make sense that Heaven Canceller had something to do with Aleister Crowley. The man stayed alive for so long, most likely through artificial means. And magic didn't last forever, no matter how many times the magician renewed the spell. His body would have eventually broken down. That only left science to keep Aleister Crowley alive.
And when one thought of medical science in Academy City, one immediately thought of Heaven Canceller, the doctor so good at his job that he seemed to defy the gods.
If he questioned the doctor, he could find a way into the building, even if the doctor couldn't physically get him inside.
Still, Accelerator was reluctant to interrogate the man, especially if he had other means at his disposal. Not only had the frog doctor saved him several times, he also saved Celeste once, and possibly could do so once again. He didn't want to get onto the man's bad side, no matter how infinite the doctor's patience sometimes seemed. Every human had their limits, and he wasn't quite willing to test the doctor's.
As for GROUP…
Tsuchimikado seemed like Accelerator's best bet. The blonde seemed to know too much about Academy City and magic. He knew about Aleister Crowley and he had followed Celeste when she left to summon the fallen angel. The more Accelerator thought about it, the more it made sense that Tsuchimikado would know a way for him to meet Aleister Crowley.
The boy stood, the chair clattering violently as it threatened to fall, but steadied. He walked towards the apartment door, levelling a stare at the two Misaka clones and Yomikawa.
"I'm going out," he said, and slammed the door behind him.
Once outside, he paused for a moment, frowning. The two brats seemed strangely quiet for the past few days, since they had returned from the war. It was almost like… No. They were tiptoeing on eggshells around him. Tch. Smart brats.
As Accelerator walked, he flipped open his cellphone and scrolled down. He paused for a moment when Celeste's name popped up, but he shook his head at irrationality and continued scrolling until he got to Tsuchimikado's name.
The boy picked up on the third ring. "Hello?"
"How do I get into the Windowless Building?" Accelerator asked, skipping the greetings and pleasantries.
He heard Tsuchimikado sigh on the other end. "I knew you would reach me eventually… Meet me in front of GROUP's former headquarters."
And then Accelerator was left listening to the dial tone. He raised an eyebrow, but complied. It wasn't like he was afraid of traps or anything. He was the strongest level five, even without the wings he somehow developed a while ago. If Tsuchimikado tried to corner him, he just had to squish everything in his way before forcing his way into the building.
Thankfully he didn't need to.
When he arrived at the run down place, more suited for rats and cockroaches than humans, Tsuchimikado was waiting with Musujime Awaki. The older girl had always tried to avoid him after he had beaten her into the ground when she stupidly assumed he had gotten weaker and confronted him. He didn't really care, even when he found out that she was in GROUP along with him. He preferred to work solo anyways.
But he really should have expected. She was quite close to the dark side of Academy City, even more so than the other former members of GROUP. And most of all, she was a powerful teleporter.
"Tch. She can get me in?" Accelerator growled, eyes never leaving the girl.
She fidgeted, refusing to meet his gaze. Tsuchimikado nodded, a half smile on his face. Accelerator's eyes scanned the girl, almost judging.
"She got me in, and a few magicians before me too," Tsuchimikado said. "She's one of the only few teleporters who could get you in, and the only one I know of."
"Tch. Kusotare," Accelerator said. "Let's go. And if you get me in and out, I'm not going to kill you."
Musujime visibly shuddered, sending Tsuchimikado a look that would have been called 'pleading' if it was on a less prideful girl. But the blonde shook his head, shrugging helplessly with a smile on his face. And gulping, the girl scurried behind Accelerator, making sure not to walk too close or too far.
The walk seemed to take forever, but they finally stood in front of the Windowless Building. From outside it looked so innocent, yet it held something, or someone, Accelerator would like nothing more than to kill.
He glanced at Musujime. "Let's go."
