iirc she is Holo younger sister and years ago mc took Holo with him (in a "kidnapping" way basically), so she ended growing up resenting humans after witnessing this "kidnapping", so yeah lol
I'm waiting for her to say

"Umm, humans don't live that long, I'm in my 20s....."
"You're lying!"
"Um, no miss. Humans live maybe 60-80 years. Barely over 100 at most."
"....."
