Tetsu

テツ

Tetsu is a young boy residing in Rush Valley, a town in southern Amestris.
Because an unknown accident necessitated replacing his right leg with an automail prosthesis, Tetsu depends on Atelier Garfiel for mechanical maintenance and repairs, particularly on Winry Rockbell, the atelier's attractive new apprentice.
While Winry is away in Central City for an extended period, Tetsu is among the clients who contact her by telephone, eagerly asking for her quick return. He also cheekily remarks that he would rather have a pretty girl like Winry working on his leg than Chief Engineer Garfiel.
