They're the ones that got mutated
Did they ever get mentioned before hand, cuz idk if I forgot them
Yeah, we see them arrive on the floor, we see them being captured, we see them being mutated, we see them fighting on the enemy's side (black and white), we see them fight the Sword Emperor on the current timeline, we see them coming back to their sense when Junho kills the boss's brain, and we see them making a suicide bomb attack on the body, destroying it.
Thanks! Lwk they are forgettable tbh
Who was the couple
