Princess Principal: Crown Handler - Chapter 4: Fabulous Platypus

Princess Principal: Crown Handler - Chapter 4: Fabulous Platypus is a single-episode OVA released in January 2026 as a bonus feature bundled with the Blu-ray release of Princess Principal: Crown Handler Chapter 4. This slice-of-life short offers a lighthearted companion piece to the main series, providing fans with additional content featuring the familiar cast in a more relaxed setting.

The OVA has already finished airing, making it available for immediate viewing to those who purchase or access the physical release. As a bonus episode rather than part of the main narrative sequence, it serves as supplementary entertainment for dedicated viewers rather than essential viewing for following the overall story. The inclusion of this short reflects the franchise's approach to giving fans extra material beyond the primary series episodes.
