Those elves appeared quite young, at least... if judged by human aesthetics.
The oldest looked like a human at the age of twelve or thirteen, while the youngest resembled a child of five or six.
Of course, with El Moonlight as a precedent, Bento knew that even the smallest-looking elf likely had an age old enough to be his elder brother.
However, he noticed that these elves had different hair and eye colors compared to the Elf Girl.
There were blonde ones, red-haired ones, as well as brown and green-haired ones, but none had the gray-black hair like him and the girl.
According to the players' knowledge, the elves in the "Elf Kingdom" were also divided into many tribes, and the best way to distinguish them was by their hair and eye color.
Different hair colors indicated that these young elves and the girl were not from the same tribe.
