After finishing the first day of her 36-hour birthday festival, Hibiki Riona heads to take a bath and announces the upcoming sleep endurance stream. The "Mindfulness" ED video played to close the stream praises viewers with "You look like wakame," then instructs an absurd breathing technique: "Inhale for 16 seconds, hold for 45 seconds, exhale for 1 minute." Viewers play along with "Wakame~" but react with agonized laughter like "Gu, gurujii..." and "Ku, kurushii..." as they endure the sixth mindfulness session of the day, wrapping up the festival's opening day.
