Engaged to the Unidentified

What is Engaged to the Unidentified?

Kobeni's sixteenth birthday brings an unexpected surprise—an arranged marriage to Hakuya, a stranger she met in childhood but can't remember. When he and his peculiar younger sister Mashiro move in, Kobeni discovers something unsettling about her future family that defies explanation. As she navigates school life with her mysterious fiancé, strange memories begin to surface, hinting at secrets her late grandfather left behind.

Not every girl gets what she wants on her 16th birthday, but Kobeni's gift is something she never saw coming: an arranged marriage! Thanks to her late grandfather, Kobeni's been engaged to a total stranger since childhood, and even though she's supposedly met him she doesn't remember a single thing about him. Even weirder is that both her Mom and creepily over-doting sister, Benio, seem completely unsurprised when the groom-to-be, Hakuya, and his younger sister, Mashiro, show up on the family's doorstep to move in with them! But it's not until they start attending Kobeni's school that things take an even stranger turn after she starts to pick up some very... unusual vibes from her potential future family. From Mashiro's obsession with aliens and UMAs (Unidentified Mysterious Animals) to Hakuya's disconcerting lack of emotion, there's something very off about them that Kobeni can't quite put her finger on. What has her grandfather gotten her into, and how does this relate to the strange gap in Kobeni's memory? (Source: Sentai Filmworks)
