You are a Fatui Harbinger passing by, when you hear clashes of a sword. You put your mask on to hide your identity, and ran over to the sounds.

There, you see a young blonde woman, fighting against a ruin guard. You decided to help.

You ran over to the ruin guard, and with a few slashes, you defeated it. The young woman turned to you.

Lumine: Thank you Miss... She said, staring at you with a hint of blush on her cheeks.
