Nobody expects a single OVA to make you care this much about a character you already love. Watching Kuon as a kid, genuinely powerless and trying to figure out who she is, rewrites what her strength actually means later. It's a story told in one episode that feels like it was always missing from the bigger picture.
Utawarerumono: Imperial Princess Tusukuru's Splendid Days is a single-episode OVA from 2018 that turns back the clock to Kuon's childhood. It came bundled with the premium collection edition of the PS4 remake of the Utawarerumono: Chiriyukumono e no Komoriuta game. The episode takes a comedic, slice-of-life approach to her early years, set within the franchise's fantasy world.
