Atarashii Gakko: Otona Blue. Reaction and walk through by AJ Hartley ( Atarashii Gakko, 1)

In case you haven t seen this great and quirky Japanese female group. Smart, talented and funny. This song s title puns on buru the Japanese pronunciation of Otona Blue : adult blues, and otonaburu (大人ぶる) to act like an adult. While they work with various composers on their musical arrangement, they do their own choreography and write some of their own lyrics, including those for this song.
