A messenger becomes a warlord for the sake of vengeance.

A story about an orphan girl who taught herself the way of the sword. After the end of the war between two nations, she joined the assassin's guild in search of a white haired assassin who personally killed her adoptive family and friends. (The story starts after the war. P.S. The story was written with pre-made characters that aren't specifically tailored for this story. Some of the settings are from Ragnarok Online, but the characters are not.)
