Starsword "Rising Nova"

A weapon that reads the biological information of its user and changes shape to suit them. In Valerie's hands, it turned into a sword as a result of the Hero of Famelle's tutoring. Emi, an Ancient who settled into Reigrad, gave it to her without mentioning its original purpose of fighting Stardeities. It will bring out its true power upon mastery, but as far as Valerie is presently concerned, it is only an "extremely sharp sword".
