From PASH! Books, the third volume of the book and the third volume of the manga adaptation are now available. I was reincarnated into a world of warfare reminiscent of the early modern era, where musketeers engage in combat. As a commoner lieutenant, I am assigned to the 6th Special Operations Brigade, which is known as the 'Death Brigade' and consists entirely of women. The brigade commander seems to have ulterior motives, the non-commissioned officers are carefree, and the infantry are mostly inexperienced girls. If things continue like this, everyone might die in battle. I have to do something... but what!? *Serial publication period: April 11, 2021 to April 28, 2023 (ongoing with epilogues and side stories).
