Wakae Mikiko, 39 years old, unmarried but with a live-in boyfriend, rented an apartment in a mid-tier building.
After notifying Nakano Eri, Nanahara Takeshi immediately went to check Wakae Mikiko's apartment and found...a whole box of various clothes and strange toys in an instant.
Of course, that wasn't the focus; it was completely unrelated to the case. The key point was that Wakae Mikiko's home also contained many women's self-defense tools, and like another female victim, Kikumoto Ayaka, most had been purchased in bulk several years prior.
Her live-in boyfriend also couldn't explain why she had bought so many self-defense tools since they weren't together at that time.
Besides that, Wakae Mikiko was just an ordinary woman with an ordinary job and an ordinary life...if you disregard the XP.
