Sequel to Uchuu Senkan Yamato 2205: Aratanaru Tabidachi.

This episode aired prior to the original series and introduces the main characters.

Grade schooler Yuuta Tomonaga stumbles upon Deckerd, a humanoid robot under construction by the Japanese police, built to fight advanced forms of crime. Yuuta's constant contact with Deckerd gives the robot a "heart," or personality; when Yuuta is recruited as the "boss" of the "Brave Police" as a result, a true human/robot partnership occurs.
