Celestia was a notorious liar - to the point of earning the nickname "Queen of Liars" - and so it is difficult to determine what, if any, of her self-reported life prior to the Killing Game is fact. By all accounts, it seems she was given the given name Taeko Yasuhiro and born into a likely working-class family in the capital of Tochigi Prefecture, Utsunomiya where she came to love its most famous food, gyoza. As mentioned in Danganronpa Kirigiri, Celestia had been a gambler for at least 4 year.
