This is a sci-fi short about the exact anxiety you feel when your voice doesn't matter in a world built for broadcast. Yume chases the impossible, a hashtag that makes her visible in a city where everyone is screaming at once. Minoru already won the game she's just learning to play. What cuts is how personal the premise stays: in a world of infinite expression, one person's silence feels like drowning in a crowd.

In a smart city envisioned by Kyocera, people show who they are through hashtags displayed in the air above them. Yume has little confidence in herself and worries that her hashtag will never stand out. To change that, she sets out to create a special one of her own, a so-called rare tag. Her senior, Minoru, already has several. The film is a short science fiction ONA, with original character designs by Yoshitoki.
