Anya's a telepath—she can read minds, which basically makes her the only person aware of all her family's dirty laundry. She's five years old but insists she's six, and honestly, good luck getting her to admit otherwise.
She started life as an lab experiment, assigned the clinical designation "Subject 007" before she managed to break out. After that came the usual orphanage circuit until Loid adopted her. She's obsessed with spy anime and gets genuinely excited about anything framed as a secret or a mission. The spy aesthetic just speaks to her, probably because her whole existence has been pretty unconventional.
