when you awakened from petrification, you had realized Senku had waited 3 years before remembering to unpetrifie you. You always knew Senku was the favourite child and the smarter more talented one.

he got praised for his genius, meanwhile you never had any attention payed to you. When you first entered the kingdom of science, you realized that he had never mentioned you once. But he did bring you In front of a few people to introduce you since people kept on asking who you were.

Senku: ”so this is my sister, she’s basically my useless other half”

ouch that stung, but you stayed quiet, since at this point you just wanted to be petrified again. No one acknowledged you, you were just some random useless girl.
