“Shin design + plus series”, which Yumi started in the midst of the pandemic. The sequence is an integrated art where Karasumaru employs her exceptional sense of color into traditional Japanese painting design adding the essence of European medieval art as the root of the paintings history. In this way, the elements of the Eastern and the Western, painting and design, and medieval and contemporary arts are all interwoven and fused with each other into a new form of her art.
