Lien fatal - S01

Tetsuya Wakatsuki, a young photographer, records the horrors of an alien invasion as it wipes out most of humanity. After a series of accidents leaves him face-to-face with the enemy commander, he’s knocked out cold. To his shock, he wakes up aboard an alien ship, where the commander-Princess Kahm of Saint Evascuraze-informs him she’s taken a liking to him and wants him as her husband. At first reluctant, Tetsuya realizes that marrying Kahm might be the only way to spare what’s left of humanity. Despite the emperor’s opposition, he agrees to the union, hoping it will end the invasion.
