The Secret Agent from Wuthering Waves

Lysithea is the eldest daughter and heir to House Ordelia. Her family suffered greatly due to their involvement in House Hrym's revolt against the Adrestian Empire. The Empire took control of House Ordelia and subjected Lysithea to horrifying Crest experiments, resulting in her possessing both a Minor Crest of Charon and a Major Crest of Gloucester but shortening her lifespan dramatically.

Kronya was born into the Agarthan society, a hidden civilization that thrives on manipulation and control. Trained from a young age to be an assassin and spy, she quickly excelled due to her cunning and sadistic nature. When tasked with infiltrating Garreg Mach Monastery, she posed as Monica von Ochs to gather information and disrupt the Academy from within.
