About the Song
Marukaite Chikyuu (まるかいて地球; Draw a Circle, There's Earth) is theme song of the first and second season of Hetalia: Axis Powers, aired on January 24, 2009 by Studio Deen. It is sung by Daisuke Namikawa and composed by Conisch. The anime itself has five seasons and tells about the adventures of anthropomorphic countries as they live through historical events and interact, with focus on differences in culture. The version used in Taikojiro is the fusion of eight different versions of the song, known by Hetalia fans as the "World" version.
