Space Battleship Yamato 2199

A World I Once Saw (1x11)

:

Melda Ditz, a Gamilan pilot under the custody of Yamato, is given a medical examination by Dr. Sado and is found to be identical to humans at the DNA level, except for the blue skin. She claims that their attack on Earth was not unprovoked, and that it was the Terrans who first fired without warning during the first contact between both races years before. Daisuke, whose father was killed in the attack, does not believe her at all until Yamazaki, the sole survivor of his father's ship, reveals to him the truth about what really happened that day. At the end, Ditz is given four days of food supplies and leaves the ship on friendly terms.
