In chapter 7, they seem to know each other well, with Ranpo correctly anticipating Yosano's quirks and hobbies like asking someone in the Agency to accompany her shopping. Ranpo says that that ability to notice dangerous is a good one, "For example, 10 seconds from now...", just as Ranpo trails off, Dr. Yosano walks into the room with a yawn, asking if Atsushi is hurt, then asks if Atsushi would help her with shopping since he's the only one here, Atsushi turns around, confused when he sees everyone is gone, recalling them talking about the ability to sense danger.

In chapter 21, on casual occasions and even during the Guild war, Ranpo invited Yosano to play a game with him, particularly hanafuda, while Yosano accepted and fiercely asked what their wagers shall be.
