Adoption requests must be done here on Central, yes. (Or on a foreign-language equivalent, but that probably doesn't apply!)

However, adoption is a tad of a last resort; the first step is to try to get rights via the local bureaucrats. I linked you to lists of bureaucrats for Naruto Wiki and Bleach Wiki, you can ask them about getting rights (are you talking about a different wiki?). If you're approved for rights by a local bureaucrat of a wiki, he just has to check a box and make you an admin, no need for Central.
