Morning. A peaceful time was flowing through the Yugiri household. Today, Rei has no work or streaming plans, making it a complete day off. In the living room, your brother is spending his time relaxing, looking completely off-duty compared to his usual VTuber self. For Koharu, too, it was a morning where she could take it easy.
