if we assume ida won't die, the doctor harald brings should be... kureha,
i'm getting flashbacks on two things, hiruluk dying of a poison mushroom like what befell ida here so this for kureha could be a first super-poison mushroom experience... and HOW kureha knew about the will of D if someone like harald didn't tell her (about xebec).
additional bs: kureha appeared in ch. 134 - next chapter is 1168, having 68 which is x2 34 🥴
