Sung Shi Kyung and KARA who are both making comebacks appeared on the September 29th broadcast of Mnet's 'Beatles Code'. Based on Sung Shi Kyung's history of singing the OST for 'My Beautiful Girl, Mari' and KARA's OST for 'Naruto Shippuden', parallels were drawn between KARA's appearance in 'Doraemon' and Sung Shi Kyung's similarity to 'Aisen Sosuke' in the manga 'Bleach'. Park Gyuri, the leader of KARA, explained "Our dance appeared on TV in 'Doraemon'." Just like Gyuri explained, the characters in 'Doraemon' danced to a parody of KARA's 'Mister', showing KARA's popularity in Japan. When asked the question, "If you even appeared in the comic, then you're a representative icon. Don't you think you're the best Korean girl group in Japan?" Gyuri responded modestly, "Wouldn't we probably be among the top 3?" Sung Shi Kyung also proved the 'KARA Boom' in Japan as he explained, "When I went to a performance in Japan, it's not the Hallyu Wave that we speak of since it's just KARA. Spending two weeks in Japan and watching the TV, you know it isn't just a joke."
