I find it rather repelling to give a simple answer to a question that warrants a simple answer like "Yes", "No", "I don't know" and so on and so for. So, I would first explain the factors that would kindle some fear in me. The avatar and signatures exude some aura of mystery and menace all at once. But at alas, it is only 2D!
If it were to manifest in full shape and form right before me, I would feel reason to be scared. However, since this is not the case, I cannot reply in the affirmative. Nice avatar though.
By the way, is the gameplay for Ar Tonelico or the storyline really that good? I have heard bits of the OST on Youtube, and it was impressive. Fell in love with it.
