It's probably the obviously enchanted grafitti.

You might be the only one Noah.

And yeah, the walls are painted in garish colours and can't be un-painted. If you weren't feeling something strange I'd worry whether you were switched on or not.

Once you meet Felix someday, you'll want to kill him yourself.

Felix doesn't need magic to nearly kill himself.

So, did Noah finally learn to communicate with Ciel without speaking out loud, or will he further cement his reputation as a weirdo?

Wait... Is the whole landscape under someone's magic ability? Is the paint like an area of control?

Noah dos not need to look in a reflective surface or close his eyes to see Ciel now? Or is he walking around with his eyes closed?

Strong words bleeding eyes boy.

It does look somewhat deserted.

Dun dun dun

Noah's power is interesting. And now he can talk to ciel without using his voice I assume ? Different color of eyes and speech bubble, that's a cool way to show it

Noah can talk with Ciel ever since the magic sensing class.
