#80 of Pumpkin Novels, this label is famous for game adoption, however it suspended sometime in 2011, actually the publisher ceased to make any publication around that time.

Another thing this label (in)famous for, they found of cross-page illustrations but their bookbinding is terrible, usually the joint part is over-glued makes it hard to scan flawlessly.

Before the discontinuation they published novels for all 3 installments from Ikusa Otome Valkyrie series, altogether 6 books. The first two already exist in e-hentai gallery:
Vol.1 (#051)
Vol.2 (#060)
this is the 3rd book of the first installment (戦乙女ヴァルキリー「あなたに全てを捧げます」) and is the only one not written by 高橋ショウ(Takahasi Syou)

the 4th and 5th book are from 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…」) I'll scan them soon.

the 6th book is from the 3rd installment (戦乙女ヴァルキリーG ~戦乙女達の黄昏~) which I don't have the copy yet.

there's no info on mugi database yet.
