Even though this little girl was looking straight at him, Ben still wanted to believe that it was all just a coincidence and this little girl was not aware of his presence. With that belief in his heart, Bem tried to slightly move to the side. But unfortunately for him, the eyes of the little girl perfectly followed his movements.
With this undeniable proof, Ben had no other way but to believe that, his super powerful ability which could even fool extremely powerful monsters was useless against this little girl.
After seeing that hiding anymore would be useless, Ben decided to show himself. But he did not get too close to the little girl as he was still worried about what she actually was. This place was still a part of the dangerous Desolate Plains of Gahana and it was impossible for a random little girl to appear here.
