Mondaiji next season might be kinda like that, except the MC might be more useful than the one in Sekirei. The staff doesn't seem very strong, unfortunately. Diomedea and the director of Campione are working on it, but the director also worked on Nanoha A's so you never know!
I'm still hopeful for it, lol.
Im really excited for Mondaiji ever since I saw those super cute bunny girl designs and the plot.
