It is later revealed her aforementioned distaste towards the school was because of being constantly left out by every single one of her classmates and that she struggled to make friends up until got dragged into Gauma and co.'s conflict against the Kaiju Eugenicists. The desire to participate and fear of being left out for the second time was what ultimately warped one of Kaiju Eugenicists' Kaiju Seeds she found by chance into the loyal and unique Goldburn that soon proved both it and its creator Chise to be valuable assets for Gauma's team.
