Nico

Nico (ニコ, Niko) is the former partner of Acta in Black★Rock Shooter ~Innocent Soul~.

Appearance
Nico's default form is similar to that of a bee or a rabbit with two wings sprouting up from it's body. When transformed, Nico takes the form of a large hammer wielded by Acta.

Personality
Nico is shown to have something of a superiority complex to Black Star soldiers. This is shown when Nico is uncaring of Acta's death and criticizes Rock for trying to save her.
