Kaire

Kaire (カイレ) was the user of a World Class Item, "Downfall of Castle and Country".

Appearance
She is an elderly woman wearing a silver colored traditional Cheongsam embroidered with a golden colored dragon.

The Bloody Valkyrie Arc
As she was accompanying the Black Scripture, they were attacked by one of Shalltear Bloodfallen's summoned kin, which they easily killed. After Shalltear made her appearance, Kaire tries to brainwash Shalltear with her "Downfall of Castle and Country". Shalltear senses the immediate danger and targets her with Purifying Javelin. As she launched the projectile right at Kaire, Cedran steps in-between them and attempts to block the attack with his shield. However, the javelin easily pierced through him and his shield, inflicting a severe injury on Kaire, effectively preventing her from completing the mind control.

The Lizard Man Heroes Arc
There are now people trying to mend Kaire of her wounds. However, her recovery rate is slow due to Shalltear's Cursed Knight class that render wounds hard to heal.

The Ruler of Conspiracy Arc
During the meeting of the highest authorities of the Slane Theocracy, it was mentioned that Lady Kaire had succumbed to her wounds and died.

Abilities and Powers
As the user of Downfall of Castle and Country, Kaire can mind control even a target with perfect resistance to mind control. Yet her own combat capability seems low due to her old age.

Trivia

 * Kaire seems to have a high social status as the Captain of the Black Scripture addresses her as Lady Kaire.
