I wonder whats so special about the landlady besides being number 1 and not winged
Her position as the God's Seat. Basically, she's as far or more above the other sigle numbers as Karasuba is against a regular Sekirei. She has her full powers, unaltered and unrestrained. Miya was literally wiping out battleships, from miles away, with a single sword pass.
In this case, though, Mutsu understands a basic truth. If they force Miya to fight, Karasuba will show up to challenge her. And if the two of them go at it, all of Tokyo, at least, will be destroyed in the crossfire.
