碇真嗣
is the main focus of "Girlfriend of Steel", a game that is like an episode of the series. She appears as a transfer student at the Children's school, and becomes the focus of Shinji's interest and Asuka's jealous ire. She is the pilot of another man-made replacement for the Evas, the "Trident", whose combat skills are somewhat more on par with the Evangelions', to whom they bear a resemblance in design compared to the "Jet Alone" robot. She also appears in "Shinji Ikari Raising Project". Like many "Evangelion" characters, Mana's family name, Kirishima, is taken from a World War II battleship.
