What if the landlord has learned about the Sekirei?
I am having dark thoughts about that man, and I think he is an insanly angry man. I'm also thinking that he was antagonizing Minato Sahashi possibly for being a ronin. Later one night he discovred that Minato had Musubi with him and he evicted him almost without reason.
And if he learned about the Sekirei and finds out that his ex cilent Minato is a Ashikabi, he would ether halved Minato locked up in prisson, forced in a work camp, chased out of the country for good, or worse put to death in the electric chair, and become president of Japan and turn it into a communist country.
