From my Fantasy Mythologyverse
The second eldest of 6 siblings, Reta found herself lost and alone after being blown away from her family. Unable to make friends with others due to her deadly poison, she immediately clung to the immortal Hulijing Atsushi.
In spite of finding her initially annoying, Atsushi later learned how important he was to her, and accepted her company. Over their time together, the pair would later become close friends, as well as powerful partners.
