辺境貴族の長男に転生したノイエ。魔女であった母から言葉を学んだため女言葉しか話せず、周囲を驚かせることもあるが、誰もがその有能さを認めていた。持ち前の頭脳と現代知識を活かした奇策が、領内の内政の要だったからだ。だがある日、彼は幼い王女を狙う刺客と遭遇し、魔女の秘術で撃退、更に彼女を虐げる王侯のクズっぷりを知ることに。ノイエは決意した。奴らを成敗し国ごと手に入れると！最強の軍師兼戦士が瞬く間に成り上がる、超爽快逆転劇開幕!! Having been reincarnated as the eldest son of a frontier noble family, Neue is recognized by everyone for his exceptional abilities. Because he learned language from his mother, who was a witch, he speaks only in a feminine manner, which sometimes surprises those around him. His clever strategies, making use of his intelligence and modern knowledge, have become the key to governing his territory. One day, however, he encounters assassins targeting a young princess and defeats them using his mother's secret witchcraft. He then learns just how corrupt the nobles who oppress her truly are. Neue makes up his mind: he will punish them and seize the entire kingdom for himself! The thrilling rise of the strongest strategist and warrior begins!
