A term coined by fangirls to describe the yaoi pairing of the Kingdom Hearts II characters, Axel and Roxas. Many accept it as canon(Based on lines such as,"(Roxas) made me feel like I had a heart"), however, many others say that the Axel-Roxas relationship is more of good friends or brothers.
The name is derived from the Japanese names for Axel and Roxas, AKUseru and ROKUsasu, respectively.
