Yes it really is a shame, but I understand their plight. I gave Madelone a low number because of her childish like appearance and to a point, innocence. Also because aside from the single digits the number of a Sekirei doesn't have as much to do with power as most Sekirei think.
Now that I think about it as much as I love star, I'm especially sad to see Leo go, I hope we get more Ashikabi soon. For balance and because I don't want the Sekirei to feel too limited in their choices. I'm going to shamelessly advertise in the discussion thread, see if we can get more people interested.
