Trivia
Etymology
"Rubea Stiria" is Latin for "Red Icicle."
Rubeus is the Latin word for "red." As an example, Rubeus Centrum is another Granblue item that uses this word (in the English translation). While the Japanese uses the masculine form "rubeus," this was corrected in the English translation to match the feminine "stiria"
