Akema and Akera
Akema and Akera are both characters in Extinctioners.
Akema and her twin brother, Akera meet horrible fates in an auto accident that cost them both the usage of their arms. Takemitsu helped them by giving them cybernetic prosthetics in exchange as acting as his body guards. Of course, since then both have gained a far deeper relationship with him than employer and employee.
Akema's cybernetic arms allows her to generate energy whips while Akera's cybernetic arms allows him to generate energy sabers. They both first appeared in Extinctioners issue 12.
