Reika Chang (レイカ・張) is a Chinese-American singer who performs under the name Vision. In Double Vision, she travels to Megatokyo to start her world tour, but her music career is merely a facade. She is the elder sister of Irene Chang, who was murdered by the Genom Corporation in Born to Kill. Moreover, she is an heiress to the "Hou Bang", a powerful Chinese clan bent on destroying GENOM and the American firm Gulf & Bradley - both of whom are collaborating on a Super Boomer project. Linna eventually manages to help Reika abandon her path of revenge and convinces her to continue her singing career.
