Talk:List of Minor Characters in the Clockwork Lullaby Series/@comment-33950880-20171228235244

The final theory I can come up with for the Mysterious Rin singer is that she is Luna Hazuki

Wordplay does refer to Tokyo in one of the PV texts which if the PV is still fully canon that the singer would have to come from the First or Second Period and based on Luna being a scientist she could fit into Full Moon Laboratory and with Clockwork Lullaby with her always being there. I think it would also fit with the characters themselves not knowing anything about Luna and this extended to even the audience not knowing anything about her.
