Viscount Joisontak

Giebe Joisontak, also called Viscount Joisontak, was formerly the governing noble of the Ehrenfest province of Joisontak. Karstedt's deceased third wife Rozemary was his younger sister.

When his younger sister Rozemary married the prominent archnoble Karstedt due to her abundance of mana, Giebe Joisontak and her other mednoble relatives began to make demands of the family that overstepped their authority. That spurred a conflict between Rozemary and the second wife Trudeliede, which eventually grew to encompass the whole family, including Elvira and Karstedt. As a result of the stressful situation, Giebe Joisontak's already-frail sister passed away.

When Rozemyne was introduced into noble society and baptized as the daughter of Karstedt and Elvira, many of Rozemary's relatives believed that she was actually the daughter of Rozemary. Accordingly, they tried to approach her on several occasions to take advantage of her new position as the adopted daughter of the archduke. However, they were repeatedly rebuffed.

Viscount Joisontak was one of the culprits behind Charlotte's attempted kidnapping and Rozemyne's poisoning. When called in for questioning, he claims that his only target was Charlotte and that he never intended for Rozemyne to be harmed. In fact, he hoped that the scheme would help gain Rozemyne's favor for her "true" family. Much to the dismay of his interrogators, Viscount Joisontak appears to have been manipulated into taking the fall for a third party.

Viscount Gerlach, believed to be the true mastermind behind the attack, is eventually released from custody due to lack of evidence. Meanwhile, Viscount Joisontak is executed for the crime of attacking a member of the archducal family.

Spoiler from Part 4 Volume 4 Due to the severity of his crime, his entire house was eradicated and all his relatives executed alongside him.


 * His name ジョイソターク (Joisotāku) is an anagram for そくたいじょう (即退場, sokutaijou), which means "quickly removed from story". This is fitting to the fact that he was executed shortly after merely appearing on page for a few times.
