Alderamin on the Sky

ねじ巻き精霊戦記 天鏡のアルデラミン

Ikta Solork wants nothing to do with war and would rather chase after older women, but he grudgingly sits the Katvarna Empire's high-grade officer exam as fighting against the Kioka Republic escalates. Alongside the swordswoman Yatorishino Igsem and Princess Chamille Kitra, whom he pulls from the sea, he finds that his talent for reading a battlefield turns him into the commander his troops actually want leading them, whether he likes it or not.
