'''Who ever said it was Aleister? nobody. It's probably somebody else. we don't know.'''

Whoever said it is NOT Aleister? Nobody. It may be him, may be somebody else. We don't know as of now. It is just a speculation. But the most logical culprit that you would think of is him.

And why Aleister? Since he has a master plan that is either being brewed or waiting to be executed. And Touma or rather "something" inside of Touma is a significant part of it. Since Touma is a significant part of his plan, I doubt he will let him die just like that unless it is part of his plan or he is taking drastic actions again to keep his plan from failing. And knowing Aleister, the General Superintendent of AC, it is impossible that he has no knowledge about the mobilizing of ALL of the Level 5's to assassinate the magic god and Imagine Breaker.
