Ai Ohto stopped going to school after the suicide of her friend Koito. Buying Wonder Eggs pulls her into a dreamlike Egg World, where cracking them open frees girls who took their own lives and sets her against the Wonder Killers born from their trauma. 'My Priority' is the hour-long special edition that continues directly from the twelfth episode and brings Ai's story to its conclusion. It opens with a recap before extending the finale, so it serves as an ending rather than a standalone entry point.
