"Nice to meet you. I am Sylvie Xilrel, the younger sister of the current Elf queen, and this is Princess Ava Xilrel, next in line for the throne…"
Jareth nodded his head at Sylvie's words and said,
"I am Jareth Ayad, the Vice-Principal of 'Ivan's Higher Arcane University'…"
Jareth glanced at Ava for a second and asked,
"I am quite surprised by the courage of the elves… You brought the heir of your empire to enemy territory without batting an eye… Consider me impressed…"
Even Jareth couldn't help but be impressed by the fearlessness of the two women.
Humans have a really bad reputation among other races, so it's quite a surprise that Sylvie and Ava had the courage to come here alone.
In the game, Ava is one of Allen's harem members, and she sacrifices her life to save Allen from a certain death.
That's the reason why Jareth has a strong impression of this little girl, and he immediately recognized her the moment he first saw her.
