Call me old-fashioned, but Yume fraternizing with this Sui girl seems a tad bit inappropriate. Hama's been missing for, what, a month or two, tops? Back in my day it was considered appropriate to wait at least a year after losing a paranormal investigation partner before hitting the pavement and seeing if there were any unpaired supernatural detectives looking to make a commitment, and you'd usually be getting side-eyes if you waited any less than 18 months before showing up to a cosmic horror cult investigation with a new +1.
