Miyako is very obsessed with catching Jeanne, to the point where she's disappointed when Jeanne doesn't show up to one of her planned thefts, and she's over the moon when Jeanne's next theft announcement arrives and contains an apology for missing the previous time. It gets even more Les Yay when we find out that Miyako's whole reason for pursuing Jeanne is to protect Maron's reputation.
Nightmare Fuel: Jeanne's bracelets look suspiciously like the ones used by Galaxia to keep Senshi who want to join her alive after taking their Star Seed, and mindcontrol them... foreshadowing?
Strangled by the Red String: Neither Yashiro and Kagura, nor Yamato and Miyako share any on-screen or on-page chemistry or romantic foreshadowing before confessing their love for each other.
What an Idiot: When Maron's classmates talk about she looks like Jeanne in Miyako's presence. It's expected that she can piece this one together and decides to not arrest Maron to protect her. But no, she refuses to believe such fact and therefore vows to arrest Jeanne to prove her point. Subverted in the manga, where Miyako in fact knew all along.
