The characters on the left appear to be "ドーアア ありがとう" (Doaa Arigato), which sounds like a play on words or a unique phrase. "Arigato" means "thank you."

The characters on the right "旋律" (Senritsu) mean "melody" or "tune," adding another layer of abstract meaning.

• High Contrast on White: The vibrant colors and dark outlines of the design pop vividly against the clean white background of the t-shirt, ensuring it grabs attention.
