The allegedly deceased daughter of the illustrious Kaida family. Though technically, this report was correct, few suspected that the bright and beloved heiress had indeed been resurrected from the start...

Little is known about how Tsubaki has spent the past few years. Certainly not as the blooming young socialite her parents raised her to be, though the reasons for that remain equally cloaked in mystery. Allegedly, she entered the Early Insert Program willingly following the disinheritance of her brother, Kaida Himawari; however, this remains unconfirmed.

Most confounding of all is Tsubaki's newfound mission. For years, there were few in Caer Sidi's high society more renowned for their humanitarianism than Tsubaki; and yet, she's returned to the public eye as leader of newly-formed faction ESCHATON, the sole objective of which seems to be destroying the Star -- and ending the lives of all Unbleeders with it.
