Rating Pistol Emanators theory is still going strong! It seems EN translation screw up again..
Credit to u/kirboswrath who I learned this from.
As you may already know by now, there's a theory that any character rated Invalid by the rating pistol curio is an emanator. This theory was seemingly disproven by The Herta's rating, which was a 4 that the gun changed into "limitless". She never got an Invalid rating
However, it seems EN actually screwed up a little. In CN, EN's "Limitless" was actually the same "Invalid" rating that was given to Acheron, Jingyuan, Feixiao, Luocha,...In CN. According to the wiki:
While the phrasing is distinctly different in English, the score of "limitless" used for The Herta in Chinese uses the same wording as those with "rating invalid" — 无法测定 wúfǎ cèdìng, "undeterminable"
So it seems the Emanators get Invalid theory is still going strong. Herta's initial score of 4 was likely because the gun mistook her for her puppets
