Saurva

サルワ

Saurva is a rival of Jahy who once vied for the No. 2 position in the Dark Realm. She was transported to the human world, where she continues her attempts to surpass Jahy.
Saurva is highly ambitious and strives to become the second-in-command of the demon world. She considers herself far superior to Jahy in both power and wisdom regarding the leadership of the demon realm. Consequently, she constantly seeks opportunities to challenge and defeat Jahy, but due to bad luck or other factors, she invariably ends up losing.
