Wasn't that obvious? Like, the first time we saw Alicia in the flashback? She had the same fighting sequence introduction in chapter 17 and chapter 39; she even had the other half of Hero Killer... The only unaccounted one is the hooded mage
Asuta! Goddamit! We need results! What tf have you been doing half of the manga?! I'm actually pissed there's no explanation for her to not get any useful intel yet.
