One of the hastily created Ludens made by ARATA MIZUNASHI.
Constructed using data from the character Lily Hopes, a certain someone's memories, and the earthbound spirits of Yamamura University Hospital.

The earthbound spirits are more of a concept—technically, even ghosts are called Ludens in this world. So she's essentially a spirit who was given flesh and made to resemble Lily. Due to lingering memories, she knows about Yurisa Yamamura. She also knows about Shina Ninomiya through Yamamura, so she doesn't seem too confused. However, her brain has been tampered with to increase feelings of love and violence, making her emotionally unstable. She's frequently angry at others and even at herself.

She is under ARATA MIZUNASHI's control and seems like a rather dangerous opponent.
