The main protagonist of the Metroidvania game Frontier Hunter: Erza’s Wheel of Fortune. It is a sequel to Tower Hunter: Erza's Trial.

Info on this game's story and characters is scarce (It doesn't have a Wiki page) but luckily, it has an in-game glossary. I took screenshots of the glossary files and used AI to extract the text which I copy/pasted into Erza's definition.
