I apologize and will do that. although space and matter are in my area of manipulation and I could have easily shattered your private dimention or found my own way in...

Aura is the essence of creation and every thing brought into creation I can bypass. not only that but my character is driven by intrigue so if you set a barrier up like that he is very likely to infiltrated it... though I should have explained that before hand. so for future reference do not try to keep Eren out of something. that is the same thing as an invitation to him.

Part of eren's character is that as good as he can be at reading people he often does not know what a boundary is and will need to be taught that and many other normal people skills.
