OOC:
So my understanding is that "Location" is a mechanical element that basically represents the information or knowledge needed to track down another character accurately enough to ambush them. It doesn't really represent a specific narrative location since that could be changing over the course of the game.
If you want to meet someone for dramatic reasons, then you can come across their narrative location as long as it makes sense in the fiction (like when Taizo surprised Aaron in his car during saevikas's first scene. Taizo didn't have Aaron's "Location" but he still met up with him to interact).
So I'm proposing that Lacy comes across Takezo's narrative location by following clues stemming from the peacock. Since I'm not interested in mechanically gaining Takezo's "Location" right now, then the interaction can shift away from the phoenix and instead to the fact Takezo is a Oni Hunter, which would capture Lacy's attention because she is interested in gaining Sumomo's Secret. She would ask for advice about how to search for information about an Oni since an Oni Hunter might be particularly good at researching or investigating Oni related-information.
Exactly how the interaction switches from Lacy searching for the phoenix thief to the subject of investigating Oni will be determined by how the scene plays out, but I could envision lots of options. For example, Takezo sees Lacy coming and intercepts her before she sees the phoenix and deceives her or charms her. Alternatively, Lacy actually does discover that Takezo is the culprit, but he bargains with her or threatens her. Anyways, that part would be up to you.
If I feel like the characters might have formed a bond during the interaction, then I might finish the scene with a roll for an Emobond. If successful, we can each choose whether the bond was positive or negative depending on how we felt about the interaction. If it doesn't seem like an emobond is appropriate then I'll finish with the Investigation roll for Sumono's Secret instead.
