Engaged to the Unidentified plot recap, spoiler-light
Kobeni Yonomori is a sixteen-year-old high school student living with her mother and eccentric older sister, Benio. On the day she reaches this milestone age, her ordinary routine is completely upended by the revelation that she has an arranged fiancé named Hakuya Mitsumine, courtesy of her late grandfather. Along with Hakuya comes his remarkably small and youthful younger sister, Mashiro, and both of them abruptly move right into Kobeni’s household.
As they begin attending the same high school, Kobeni attempts to navigate this bizarre domestic arrangement. However, she quickly starts noticing strange and unusual vibes surrounding her new prospective family members. From Mashiro's quirky obsession with extraterrestrial life and unidentified mysterious animals to Hakuya's stark, emotionless demeanor, it becomes clear there is far more to them than initially meets the eye.
These oddities are further tied to an unexplained gap in Kobeni's own childhood memories involving Hakuya. Despite the mounting confusion and her sister Benio's intensely over-doting behavior, Kobeni tries to adapt to her unusual new daily life in Engaged to the Unidentified.
