Zetta reluctantly admitted that he'd underestimated her. Not that he'd forgotten she was a demon, mind -- if he had, he'd have probably attempted to challenge her with two million Earth Defense Force battleships, which even a reasonably capable level 70 demon could destroy in a matter of minutes. No, Zetta was rapidly reassessing Alessa as someone who, like Nanashi or Evangeline, ought to be classed with the strongest Overlords he knew.

Which, really, Zetta was just fine with, so long as he was still on the top of the heap. (Which, sadly, no one seemed willing to acknowledge despite its absolute literal truth, most likely because he was stuck as a book.)

He'd throw a challenge at her after she'd vented some energy on a horde of mooks. Even now a few of those mooks were pitching spells at her, fire and ice and wind magics exploding around her.
