In The World At The Outskirts summary: One day, a boy who really loves ciphers and Wikipedia, woke up in the body of a little girl at the outskirts. It was a different world with low level civilization. Above all, it was a fantasy world where magic exists. She continued living a tranquil life while a.n.a.lyzing the magic in that strange world, but she lost her father when he was drafted in the previous war. The seeds of war unexpectedly came to the girl one after another… The girl began to use the knowledge from her former world to keep her promise with her beloved Father, and then the enemy attacked once again. The difference in military power was about 66 times. Modern knowledge supplemented that hopeless difference, and though the victorious girl barely enjoyed her short-lived peace, the girl’s knowledge further sparked wars. An empire beyond the remote, distant oceans surrounded by conspiracies. In front of the mult.i.tudinous attacking fleet, the girl stands in the battlefield once again.
