Gray Raven is an elite group, led by Lucia, the adeptus known as Plume.

Lucia is a powerful adeptus who wields the Cryo element and a sword. When she was young, she had a younger sister named Luna, though they were eventually separated because Luna allegedly died because of an accident.

She's the aunt of Jay, Alex, Alice, and Hideo, and likes to cook. However, her cooking needs a lot of work to be done, since it was rumored that she food poisoned half d Liyue's population without even knowing it.

Liv is the adeptus known as Eclipse, and the support member of Gray Raven. She wields two levitating guns--shortened to levi-guns--which have long reach. Her element is Electro, though the color seems to be in a pinkish color rather than the usual purple.

She is the daughter of a renowned man who lived long ago, and she had a step family complete with a stepmother and step siblings. During the Archon War, she was critically injured, and turned into an adeptus to save her life. She's a skilled medic who has a simple dream.

Her kind nature makes her prone to deception and pain. As such, it's very easy to manipulate Liv, but she'll always keep a stern face even after she realizes that she's been manipulated.

Lee is the adeptus known as Palefire, and as such, his element is Pyro. He is the member of Gray Raven responsible for any issues regarding their tech, such as the state of their weapons.

He was eventually charmed by Kamui, a member of Strike Hawk, and together had Jay as their child. In the Haikyuu universe, he also gave birth to Jay's younger twin brothers, Shizuo and Izayoi.
