Reiya used to be kind and a little shy before, struggling with slavery and Arkana treating her so lowly. When she got out of her slavery, she wasn't the same anymore, way more sadist, doing to others what was done to her. With time, she gained back a little of her kindness in Akasen, times being different.
Short Story
Reiya was a random girl from the Nemeros region, until she got kidnapped by the Lust Cult of Kilya Shiverous, where she lost quite a lot of her personnality in the process. She was sold to Arkana as a slave, until she became her first wife. Reiya now free, became a member of the Lust Cult, forever changed. Now on the enslaver side, she helped kidnapping Nilah, who was corrupted like her, and became her second wife. After Inferia fell, she went to Akasen with her family and started descending into fat madness, her dick growing in the process.
