Aleister was showing signs of aging, he was carrying a lot of stress. Yuuka had brought two major treats in the city, he didn't even plan those. As soon as the city's seal was lift Yukari jumped away in a dimensional rift. He regretted not doing as Erich and keep his distance from the trouble, VIVIT was useless to Accelerator now as he had rejected the maid and asked Yuuka for proper training. At least she was teaching programming to Misaka Worst and Last Order, but who used LISP anymore but AI's?

He was still willing to know who that new girl was, he always knew about ESPers but this one was a completely new one. She was maybe the first lvl5 teleporter, Sumireko knew her but she never shared much information with him. There was no way he could see or detect her time manipulation skills, she was very careful with them which always made them seem like pure teleportation.

Then the white haired girl appeared in front of him, he didn't expect her to know the way inside, was she so reckless to teleport into a place she didn't know? Or she was so skilled she could do it without any danger? Maybe he could ask.

–Do you have a death wish little girl?

–I made this space temporarily bigger so it was impossible for me to teleport into something.

–Why are you telling me this?

–Sooner or later you will find out what I can do, this whole city is crowded with proves. In fact I am here to calm your need for information. I don't want you to check on me in the future –She wasn't going to tell him the full story, if she did he would make an artificial version of herself because he had the "materials" for doing so. Though she would get rid of him if she told him everything he thought he needed to know.

–It seems fair, I won't check on you if you tell me who you are

–Don't you want to know why I am here?

–You were looking for Yuuka… Let me guess, you want to check on her.

–This city is full of proves… I am Izayoi Sakuya, head maid of the Scarlet Devil Mansion in Gensokyo –It wasn't a lie that was her identity at the moment.

–Nice meeting you. What can you do then? Any comment in my program for teleporters?

–Yes teach them non euclidean geometry… They will thank you sooner or later. Well I can control time and space.

–Prescience?

–Only limited to my own destiny. –there it went his plan for capturing her, there was no way of catching her without alarming Gensokyo. If he tried she would find a way of causing a youkai invasion. Sakuya knew he knew that, that's why she was here in the first place.

–By the way I heard someone here has learned Master Spark… Hope it is someone loyal to you.

–So that's how that was called? What is it?

–An energy blast composed of every single type of energy. It requires a lot of power to pull it off. It can be done by a spell… But I doubt that in here. –Sakuya knew from the future that Kazakiri could fire it, the first and only person who fired it without the use of magic.

–I didn't ask if it was a spell for obvious reasons… –Sakuya left before he finished the sentence. She was here only to get him off her back and to make him understand Kazakiri was capable of defending herself.
