|Also Known As||Jessie (at school)|
Milady (by Kanon)
|Birthday||August 25, 1968|
|First Appearance||Legend of the Golden Witch|
|Portrayed By||Marina Inoue|
Krauss and Natsuhi's daughter.
In the absence of any irregularities, it is thought that she will eventually inherit the headship of the Ushiromiya family (or technically, her husband will). However, she seems to have no interest in all of this.
She was born with weak bronchi and is sometimes assailed by sudden asthma attacks.
Jessica suffers from asthma and occasionally has asthma attacks when she gets too excited. In Turn of the Golden Witch, it is revealed that Jessica secretly practices guitar and plays in a rock band at school.
Jessica appears as a pretty young girl with blond hair tied into a ponytail. She wears a dark blue jacket over a white shirt and red tie combined with a red skirt, knee-length socks and black shoes. The One-Winged Eagle is imprinted on her left sleeve.
Jessica has a very hot-headed personality. She has no interest in money or in the headship of the family and tends to act impulsively. When it comes to talking about love, Jessica often gets flustered and can barely hide her feelings. Jessica is especially strong in her feelings towards Kanon and does everything she can to make him open up to her. When Jessica gets determined, there is nothing she cannot do.
Legend of the Golden Witch
Jessica becomes one of the last survivors and dies on the tenth twilight.
Turn of the Golden Witch
At Shannon's suggestion, Jessica has Kanon pose as her boyfriend for the school's culture festival. After the first twilight, Jessica accuses the 19th guest Beatrice of being the culprit. After heading to the VIP room and finding nothing, she heads back to her own room with Kanon. There, Beatrice attacks both of them and aims to make them sacrifices for the second twilight.
Jessica soon bears witness to Kanon summoning a magic sword and fighting Goats and the Stakes. Jessica protects Kanon when Asmodeus tries to stab him and dies soon after.
Banquet of the Golden Witch
During a scuffle with Eva, Jessica is blinded when Eva's gun fires off. While resting in the servant's room, EVA-Beatrice murders Nanjo outside and plans to do the same to Jessica. Beatrice soon appears, summoning Kanon's ghost to guide Jessica to the parlor and hide in the curtains.
Alliance of the Golden Witch
As part of Kinzo's test for the family headship, Jessica is summoned to her room and encounters Ronove. During their fight, she shows extreme prowess in hand-to-hand combat, enchanting her fists with various upgrades. She dies when Gaap causes George to destroy her head with a kick. Ronove temporarily brings her back to life so she can give a message to Battler over the phone, dying again shortly afterwards.
Dawn of the Golden Witch
Jessica becomes embroiled in a battle for love between herself, Kanon, George, and Shannon. In order for her relationship with Kanon to progress, Jessica has to prove to a pair of love demons, Zepar and Furfur, that she and Kanon deserve the miracle of love more than George and Shannon. For her trial, Jessica has to choose one person on the island as a sacrifice for her love. She decides to choose the first person she runs into while walking around the Ushiromiya Main Building, which turns out to be Kyrie Ushiromiya.
After an extended conversation about Kyrie's romantic past with Rudolf, Jessica attacks her. Kyrie manages to defend herself with the help of Leviathan, however Jessica gains an upper hand when the two lock themselves in Krauss's study. Jessica uses powers bestowed upon her by the love demons to burn Krauss's study, killing Kyrie.
