Shadow Master is indeed one my more powerful semblance. But it goes with the character and their role in the story.

The user (Atsu Sumbra) grew up in the shadow of their younger brother. Where Atsu's brother was charismatic and outgoing, Atsu was an introvert and hid themselves from others.
In the story, Atsu works as an informant/assassin instead of a hunter/huntress. Really neutral in terms of alignment, but occasionally helps out and acts as a challenge/trial for the main characters.
