A New Day is Dawning
"A New Day is Dawning" (ステキな仲間たち, Suteki na Nakama-tachi?, lit. "Wonderful Companions") is the final song mission played in Atlantica in Kingdom Hearts II. It reflects the new beginning of harmony between the surface world and Atlantica. It celebrates the union of Princess Ariel, a mermaid, and Prince Eric, a human.
This song is available after Sora obtains Thundaga from the Groundshaker in the Pride Lands and returns and talks to Sebastian. In the mission, Sora must be able to earn at least 30,000 points to be able to pass and end the story. After the cutscene, Sora obtains an Orichalcum+ and a Blizzard spell upgrade.
