Sing of Innocence Keyblade

"A weapon that boosts your Magic to give it a lot more power."

The Sign of Innocence is a Keychain for Roxas's and Xion's Keyblades that appears in Kingdom Hearts 358/2 Days. It can be upgraded to the Sign of Innocence+. Both of these weapons are Magic-oriented, as shown by their Magic-enhancing abilities.

The Sign of Innocence's handle is white and its smooth, circular, dark indigo guard completely surrounds it. The top of the guard is decorated by three magenta diamonds; one at the base of the blade, and two on either side of this one. The shaft of the blade is rather short and is dark indigo. The head and teeth of the blade are comprised by a dark indigo cross with a magenta diamond set in three of its four arms, leaving the arm opposite the "teeth" bare. A white ring connects all four arms of the cross. The Keychain token is triangular and resembles the head of the blade, being dark indigo with three magenta triangles and one triangular gap decorating it.
