Airi is a gorgon-dragon, or snake dragon in simpler terms. It is rumored that Charlotte Blackheart, legendary monster slayer, lost her arm while fighting her while she was still in her original form which Charlotte calls “Demon Queen Lilith”. Moments after Charlotte lost her arm, she shot a purifying bullet at Lilith which inverted all of her physical and mental traits, creating the soft and innocent Airi as Lilith was transformed out of existence.

She has a strained relationship with Charlotte. Charlotte allows her to live because she no longer deems Airi as a threat to society, but tearing off someone’s arm does something to how Charlotte views people. Charlotte finds her intimidating and annoying. 

Despite her soft exterior, getting to know her in a good light is the hardest part, she’s really not the most considerate person out there. Airi is usually bratty, sarcastic, and flirty.
