Naruto: Gaara's Love Symbol Wristband
The Naruto wristband features Gaara's symbol (Love in Kanji) embroidered in red on a black terrycloth that stretches to fit.
From Wiki:
Gaara was once kind and had initially tried to be friendly to others, despite their fear and hatred of him, but Yashamaru's actions and words changed him. Realising that nobody loved him, Gaara used his sand to create the kanji on his forehead "love" (愛, ai), as a symbol of a "demon loving only himself", and to live up to his name, as what he believed Karura intended and Yashamaru told him. Gaara became emotionally withdrawn, silent, and consumed with a bitter loathing for everyone but himself and "Mother": the voice of Shukaku in his head. He learned to find pleasure, and eventually a reason to live, in annihilating the numerous assassins sent to kill him – and, by extension, anyone who threatened his existence.
