The 2018 anime adaptation by Troyca (directed by Makoto Kato) covers roughly the first half of the manga. In the anime, Yukina Saeki is portrayed as enigmatic and cool. Voice actress Minako Kotobuki delivers a performance that is perfectly detached, capturing Yukina's exhaustion with a world that demands she feel.
