Niken got up and walked out of the inn, following the song's source that had hypnotized her. Her gaze was blank as if someone had controlled her mind. Niken herself was completely unaware she had walked out of her room and was now approaching the lake where several mermaids were waiting for her arrival.
When Niken stood right in front of the barrier that prevented humans from getting close to the lake, Niken raised a hand. Her indigo magic circle appeared and now reformed into a dagger.
Niken directed the dagger towards the barrier, causing a rift big enough for her to pass. Once her feet have stepped over the boundary, the hole behind her has entirely sealed again.
The dagger from Niken's magic circle had disappeared. Then, she walked over to the mermaid, who was still singing to her. Niken's steps stopped as if Niken began to regain consciousness.
'Go! Get away from there!'
