It is quite impressive for the rookie group as they haven't even officially made their debut yet.  Furthermore, "Rumor" topped number one on iTunes in a total of 13 countries.  Not to mention reaching 5.5 million views on YouTube with their new music video.

DSP Media commented, "Many international fans are expressing their interest in KARD due to the group's bold and distinct image.  Please look forward to KARD's official debut in July." 

Meanwhile, KARD is currently in the middle of their first American tour.

Congratulations KARD!
