The Eternal Sorrow is a Keyblade wielded by Naku in Kingdom Hearts: Sorrowful Echoes.
Design[]
The Eternal Sorrow is fairly simple in appearance. The blade is a stylized heart, with a red gem in the center. The tip bears triangular spikes, and the stalk another
stylized detail. The gaurd is large and vaguely oval-shaped, consisting of two curves that don't connect at the bottom. The key chain is a string of silver rings, and the token is a shape resembling the blade. The blade, gaurd, hilt, token and details are blue, while the stalk and keychain are silver.
