Clearly she only kink flex if she sense potential new member.
This one she's marked as enemy.
Wouldn't surprise me if she's mentally considering the best place to dispose a body.
The full army itself is 'only 5000 according to this
Assuming all the 200 magic tool engineers + golem users are in there, based on how many columns they're taking then probably around 1000 are inside the temple itself?
This time the goal is just winning after all.
Also it's a fair question if the opponent is truly 'the best' if they can't handle something unorthodox.
Even more so if consider 'best' beyond just PvP duel and include dealing with monsters with OP powers (like Anko)
