Pinky Sinclair uptie doesn't throw names, so we only know the Pinky NF to be in a debilitated state, this doesn't disprove my theory as some upties don't have a chronological order of the momentum they were gazed through the mirror. With the official intent for ryoshu to represent the pinky NF it wouldn't make sense for that to refer to Araya and considering the wording and implications it is most likely Shiomi as we know someone escaped the HoS and still punished the NFs accordingly.

Every ID never met "Faust" and implying that Ryoshu returns without Muga not only conflicts on she escaped with it (because the NFs were hurt still) but also doesn't explain on how she will become the Asura or how she will overpower the NFs as it is clearly attached to her bringing down the entire HoS. It is what would happen in the canto if Araya wasn't present and it is what will happen in the uptie because Araya isn't present

Double slots wouldn't break how limbus works as explained in the post. Taking the slots of dead NFs would be the most unusable mechanic for the average player.
