this series can be described as ikkitousen+sekirei+queens blade! lots and lots of ecchi hence the queens blade reference. -.0 samurai's named after famous history figures...like ikkitousen, and sekirei because its a harem of girls and 1 guy not to mention its oppai-liscious!
heres one of the main characters
and yes that is her costume in every episode! no pants! O.o
