Ruminas-san participated in the "Spreading Sky Blue Song Relay." Her song selection, which evoked the passage of time throughout the day, and her singing captivated viewers (including relay participants). She also participated in the closing ceremony, striving to interact with all the participants.

In the subsequent "RUST" session, while she felt a sense of comfort with familiar faces like Otoha-san and Nanamona-san, she also enjoyed spending time with people she hadn't met since the last session.
