The Guardian Bell (ガーディアンベル Gādian Beru) is a Keychain for Sora's and Riku's Keyblades that appears in Kingdom Hearts 3D: Dream Drop Distance.
The Guardian Bell is majorly based off the Notre Dame cathedral. Its teeth are made up of a Bell held by the mouth of a gargoyle standing atop an ornamental-circular design from the cathedral. Three long strands on the Keyblade, appearing similar to the supports on the cathedral, act as the blade, with them connecting onto yet another ornamental design that is the hilt and connected to two gargoyles facing outwards, away from each other. The handle is golden and connects to a golden chain that has a bell as the Keychain.
