Yuzuki Fukui : the bartender from Kogoro in the bar episode, she looks very similar to Asaka, her hair is tied like Asaka and also her chin, and I didn’t see any one talk about her.
Ryujiro Uematsu : according to the descriptions of haibara, we can add him also to RUM suspect list, he is old man and in chapter 966 he opened just one eye.
Hyoue Kuroda : I think there is a possibility that he can be Akai’s father, Akai joined the FBI because of his father, and he said his father wasn’t an FBI agent and didn’t specify whether he is CIA agent or not, and his accident may be related to Kohji/Asaka/RUM case.
Mary: or Akai/Sera/Shukichi mother, I think she is not Asaka or RUM as Conan is thinking, and when Akai asked Ran and Sonoko about the person who is with Sera, he didn’t mean that person is Asaka.
Wakasa Rumi: we don’t have enough information about her or her background, her name may be fake to begin with, and her interest in Conan is suspicious, she was giving hints to him as she figured the meaning of the code (the time table and whisky). She may be the responsible for uploading the data about Kohji case, thus she figured that Conan has accessed the website many times through his IP.
However, she isn’t Vermouth, because she didn’t trigger haibara’s sense although she fixed her eyesight on her and talked with her, unlike when Vermouth was standing away from her in Jodie’s memories and the cherry blossom viewing trap.
