this is how people read it, not a direct translation.

day 245

" My battle with the [Flame Mother Dragon Empress] kept on going thanks to instantaneous recovery. Near the end, the  8 Demon Generals, which includes  Kanami -chan, were in the vicinity and we performed a combined attack from the sky against the Dragon. As a result, they all 【Ranked Up】."

now as you read that it seems that they ranked up after the dragon empress was defeated because it says "as a result" means it happens after the fact.

therefore they all ranked up at the same day if not the same time, that is the least i will accepted but if it was on the same day it can be considered the same time.
