Seikai no Monshou

Linn Jinto's entire life changes when the Humankind Empire Abh peacefully occupies his home planet of Martine — no shot fired, but everything transformed. As the planetary governor's son, Jinto finds himself reclassified as a nobleman and sent away to learn the Abh language and culture. It is not a future he chose or wanted. Now he is entering the next stage of his training, where he will meet his first actual Abh: a young woman named Lafiel, who is considerably more than she appears. Together they will have to fight to survive.
