Isekai Shōkan Ojisan no Jū Musō Life: Sabage-Zuki Salaryman wa Kaisha Owari ni Isekai e Chokki Suru #7

Isekai Shōkan Ojisan no Jū Musō Life: Sabage-Zuki Salaryman wa Kaisha Owari ni Isekai e Chokki Suru, translated as The Gun-Master Life of an Isekai-Summoned Middle-Aged Man, is a Japanese light novel series written by Shirataki and illustrated by Itoniku. It represents a subgenre of the Isekai trend that focuses on the transfer of specific, practical knowledge—in this case, an enthusiasm for airsoft and tactical firearm equipment—into a high-fantasy setting. The seventh volume continues the protagonist's journey, balancing comedic tropes with the tactical satisfaction of introducing modern weaponry to an environment traditionally governed by magic.

The series emerged from the web novel platform Shōsetsuka ni Narō before being picked up for physical publication by HJ Novels. The cover art and interior illustrations by Itoniku aim to evoke a distinct contrast between the mundane appearance of a salaryman and the tactical gear central to the narrative. The series has found its audience among readers who appreciate the niche blend of military otaku culture and lighthearted fantasy adventure, serving as a reliable entry in the prolific lineup of middle-aged protagonist-led stories that have dominated Japanese light novel publishing in recent years.
