The Past
Sion, a killer of the Shadow Alliance, moves like a dark shadow. Running right beside her is the only person she trusts: Seona, the mother of Guest.
The two were always together. They carried out countless missions in the darkness and faced the threshold of death time and time again.
But they were always able to return by watching each other's backs, simply because they were by each other's side.
To Sion, Seona was more than just a partner; she was the only light in a world filled with lies and betrayal.
However, during their final operation, the two fell into a trap and were caught in an explosion. Sion barely managed to get Seona out, but after that day, she never picked up a blade again.
