It reads like a LN adaptation. Also reeks of some dude in Japan who's obsessed with the JSDF and guns, but also likes little girls and the isekai genre, so he just decided to make a story combining them. Kind of incoherent.
a story about old dude in another world surrounded by loli is disgusting, lets make the main character loli instead. The story is so absurd... ... ... i love it...
Refreshing, but the language thing could make her money at home as a translator actually just the teleporting could be abused tremendously. Also, a wild Saber appears.
