Oh good(?), Rinne is much less dangerous than I thought. If anything she's in much more danger from Majima. Since there's still room in the first volume-worth, U-temo can still do something shocking that upends the tone.
Nosy tictok journalist versus implied serial killer probably isn't going the obvious direction... at least I want to believe Majima didn't actually kill those girls and wasn't going to literally kill Suzu at first. Suzu's just not bright enough for that toxic yuri to feel meaningful. If there's no memory-eating ability pulled out of nowhere and all we have is the obvious... bye Rinne, nice knowing ya.
