"Yo! I'm Nova the great! Ludens aren't so rare anymore, so I'm out here being a detective. Wanna be my client? If it's about Sagami City, leave it to me! ♪"

A Luden who works as a detective in Japan. Despite her intimidating appearance and flashy lines, she's reliable and loyal to her clients, so she's earned a good reputation. She was originally asked to collect gossip for Alice, but distanced herself once she realized there wasn't much in it for her. When it comes to knowledge about Sagami City, no one surpasses her.

Sayaka will be saved more than once thanks to Nova's deep insight and wealth of knowledge.
