#081 of Pumpkin Novels, this is the 4th book from the label that based on "Ikusa Otome Valkyrie" series, and the first book about the 2nd installment (戦乙女ヴァルキリー2「主よ、淫らな私をお許しください…」), for previous volumes:
Vol.1 (#051)
Vol.2 (#060)
Vol.3 (#080)
are about the 1st installment (戦乙女ヴァルキリー「あなたに全てを捧げます」)

I'll scan the 5th book soon, hopefully upload it tomorrow, but I didn't get the 6th atm (I actually ordered it but the shop owner posted the wrong one for me ><)
