Eiko Magami  

A-ko

A-ko appears to be an invulnerable character with superhuman speed and strength. She is the main protagonist of a series set in Graviton City, Japan. Despite being from an unusual lineage, she tries to lead a normal life and is generally friendly, cheerful, and polite. However, A-ko can become very dangerous when she's angry. She has a large appetite and a tendency to oversleep on school days. C-ko Kotobuki is her constant friend, whom she has known since kindergarten. While A-ko loves C-ko, she can sometimes be frustrated with her friends immaturity. Her powers are controlled by distinctive armbands that she always wears. Without them, her strength becomes uncontrollable and she destroys anything she touches (even things she doesn't touch). It is suggested that A-kos parents may be Clark Kent and Diana Prince, also known as Superman and Wonder Woman.
