Taeko Yasuhiro, more commonly known as Celestia Ludenburg, is a student at Hope's Peak Academy and is the Ultimate Gambler. She is known to be mysterious-like, creepy, Lolita-like, smart, composed, and formal. Although she is composed, there are times where she would snap should someone become ignorant. She can also be a bit bossy too, as evidence due to Hifumi Yamada, the Ultimate Fanfic Creator, being commanded by Celeste should he have doubts or refuses, though he has gotten used to it. In the Jurakan Universe, at Hope's Peak High, the Ultimate Headmaster Cat Makita gave her a deck of gambling cards capable of slicing though enemies and, if by chance, can even explode when hit on impact. Celeste is a 1st semester student at Hope's Peak High.
