Elisa was a ice dragon and taught Winter to use the powers that caused her and her brother to be separate. Along the journey to find her brother after she kills Crystal, she runs into a man with black hair. He introduces himself as Zeref, causing Winter to back away in fear of the immortal. That was to be expected, right? But something about Zeref made Winter less afraid of him. He informed her that the 7 years that she did not age were linked to her brother who was part of a strong guild.

Or will she just not admit that she knows who he is? Also, how will her brother, his guild and her own react to her wanting to save the most evil being in all Earthland? Read and find out!
