Cristoforo: “These Echoes are keen to find their friends too. They're not fighters, but they can surely be your guide. Why not take them along?”

Rover heads to the place where the Echoes were last seen, leaving Zani with Cristoforo.

Rover: (Everything seems normal here. Let's keep moving.)

Continuing to follow the Echoes...

Rover: (Hmm? There's something on top of that ruin. Are those... corroded frequencies? Need to find a way up there.)

Rover investigates the area.

Rover: (There are Fisalia markings on these crates. What's inside? Something's being wrapped in these strange frequencies. I should clear them out first.)

Rover transforms into Echo Lottie Lost to clear the corroded frequencies.

After clearing the area of corrupted frequencies, a Lycoris petal emerges.

Rover: (These are... petals? I think I saw them before...)

Echoes that have lost control attack Rover from behind.

Rover: (Something's wrong with these Echoes. Looks like someone's pulling their strings, just like at the rehearsal. Need to find a way to stop them first.)

After dealing with the Echoes, Rover returns to Cristoforo and Zani.

Cristoforo: “Ah! You have returned! How did it go? Any discoveries to share?”

Rover tells Cristoforo and Zani what she found out.

Cristoforo: “Intriguing. Frequency corrosion, you say? So these missing Echoes appeared out of nowhere and turned hostile? This is unheard of... Echoes are the Sentinel's gift to Rinascita. They're not supposed to turn on each other, much less humans.”

Zani: “Actually, there was a similar incident with hostile Echoes in Ragunna City recently. It was more serious, and the Echoes involved almost hurt us. That's why we're investigating.”

Cristoforo: “I presume the Fisalia you seek is entangled in this affair.”

Rover: “Exactly.”
