When a cursed phantom thief resurfaces after a decade of silence, Detective Yukari Yuki is the first to answer the challenge. The thief leaves riddles instead of clues, charm instead of violence, and a trail of stolen jewels with forgotten names. But this is no ordinary game of cat and mouse. Mockingbird hides more than just his face. Beneath the mask lies a curse slowly eroding his identity and the key to breaking it may lie with the one person sworn to stop him. Yukari thought she was chasing a criminal, unbeknownst it was someone whom she's close to. A tale of secrets, stolen memories, and the line between justice and obsession. --- Lore is half based on Zenless Zone Zero, mostly AU but still have base elements from Zenless.
