Using a keychain of the character Noba from the anime Bleach on your keys can be a good conversation starter. Noba, as shown here, looks a lot like an alien, but he isn't one.
He is an artificially created being that can stay alive by consuming souls. Noba usually is seen as a plush toy, and this is the version used for this keychain by the team at Great Eastern.
The item is made of high-quality PVC, and has a keyring and a hook made of metal. Like this, you can place your keys directly onto the product and further attach them to something else, making the keys easy to reach.
Alternatively, if you don't want to use it as a key holder, you can use the hook to attach the accessory to your backpack, purse, or other similar items. Just placing it in your Bleach collection is also a possibility.
