Akirise mix rock and hardcore music with a dash of punk, forming a genre the band refers to as "anticore fusion", something obviously uncommon. The impact of their sound is accredited to a crushing bass and competing vocal styles that clash against the irregular compositions of the music. The heavier passages are supported by rousing and trenchant riffs, which in turn are given additional energy by spat-out French lyrics regarding their country's political issues.

Since the band's formation in 2003, they have recorded their 2005 EP ("Comme Des Mouches") and full-length debut ("Brouiller L'Ecoute") in their home studio which is shared by all members of the band as their home.
