In the beginning, Hideki had a huge influence on ACID and they played a hard mix of new rock and emocore with heavy emphasis placed on his and Junpei's twin vocals. After he left the band, their songs became less focused on vocals and turned a bit more pop-ish, but still kept their "heavy" sound due to their having three guitarists.
