The manga has not confirmed the traitor’s identity in a fully settled way from the sources I found, but the story does point suspicion toward an infiltrator tied to Goetia , the villain faction behind the Terminalia attack.

What’s known

  • The investigation in the Tower is specifically about finding the traitor who helped with the Terminalia attack.
  • Reader discussion also suggests there are still multiple theories and no universally accepted answer yet.
  • Some fan coverage around chapter 52 mentions the “traitor’s identity” being revealed, but the available snippet does not clearly identify a single confirmed person.

Best current read

  • If you want the safest answer: the traitor is still not cleanly confirmed in the material I could verify.
  • If you want the likely direction of the plot: it is connected to Goetia’s infiltration inside the Tower.

Spoiler note

This is a spoiler-heavy plot point, and different fan summaries online may oversimplify it before the manga fully clarifies everything.
