Blade and Soul.

Alka is an assassin for the Clan of the Sword. She's on a journey to find the woman Jin Valel, who killed her master Hon. Jin is demon-like woman who controls the Energy of Chaos and kills without feeling - not unlike how Alka has learned to kill in her work as an assassin. On her journey, Alka encounters three strange women, each great warriors in their own right, and grapples with her slain master's wish that she leave the life of an assassin behind.
