So yeah, we got hints Kameya got roughed up like Mukai for disobeying direct orders and getting useful assets burned, and straight confirmation that the conspiracy had their caught flunky point the finger at TripleSakura once they had time to steer the narrative/coach her. Guess the only question is if the excerpt this chapter between Riko and TripleSakura is a microcosm of their normal relationship and this was just a good chance to get back at her, or if the backhandedness is because the latter is fully suspicious of the former, and getting her out of power serves some nefarious future goal. Honestly feels like a coin flip to me. Going back a few chapters, the way Sasaki gave Toudou the cold shoulder makes me think the bad guys already got leverage on her offscreen, so TripleSakura will find her a dead end in her investigation. If she goes at it alone, anyhow.
Also of note: I'd thought R was a firm M as far as things went, but it looks like she's got more than a little S, for the right kind of person. Should have guessed, given her vocation.
