If this is true, my guess would be Ringyoku dies next chapter with the other officer either being Koku Ou or Zenou. One of the latter two lives beyond the next chapter if only to secure or attempt to secure Kanki's escape.
If Kanki is to escape then it is probably going to be either Koku Out or Zenou that holds the line while Kanki escapes. Zenou makes sense for pragmatic reasons cause he is motherfucking Zenou, no explanation needed beyond that.
Koku Ou might make for a thematic option instead, since she seems to adore Kanki. That adoration for Kanki might be what allows her to hold out long enough for Kanki to escape and make her realise the truth behind Ba Fuuji's words. That she was stronger when fighting to protect something her heart adored than when she was fighting to kill.
Then again, a glaive might just cleave her skull open before her brain can have a chance to process that nice train of thought.
