Children really are amazing, huh. She had more balls than half of all their school (and human society most likely) to come up to the 2m tall alien lady and talk to her.
And props to her onee-chan, a gyaru (which makes sense, they have more balls than the average japanese student when it comes to talking to strangers), for being super chill about her small sister coming in contact with an extraterrestrial as if it was just a neighbour. “No big deal, just a big girl who is pink from my school doing a good deed and helping me and my lil sis.”
