Raynare

Raynare is a Fallen Angel and serves as the first major antagonist in High School DxD.

She initially appears as a sweet, attractive high school girl named Yuuma Amano, with long black hair, violet eyes, and a slender yet curvaceous figure. In this human disguise, she pretends to be kind and dates the protagonist Issei Hyoudou to get close to him.

Her true nature is completely different: vicious, sadistic, manipulative, arrogant, treacherous, and cruel. She has no hesitation about deceiving, mocking, and killing others for her goals (such as obtaining powerful Sacred Gears). She leads a small group of other Fallen Angels and shows a power-hungry, deceptive side, often looking down on humans and even begging cowardly when defeated.

She is ultimately defeated and killed by Rias Gremory after her schemes fail.
