Haruko Tajima's new song is a tribal and hyper rap song with beat of reggaeton and baile funk style. This song is also about "dragon key chains," a souvenir sold at every tourist attraction in Japan. These are very typical Japanese souvenirs that remind us of subcultures such as anime and video games, but in Japan they are known as nostalgic and "tacky" because they have a strong image of being something that elementary school boys beg their parents to buy for them.
