Pleasure to be here

Hello everyone, I've come online to look at which martial art I want to do in the future. I've done karate for a couple of years, and looking at starting a new style sometime in the next six months, might sound silly and premature, but I really want to learn a style that primarily focuses on restraints and lockups of an aggressor(s), being able to completely immobilize without inflicting any harm.
I was thinking most strongly toward an akido style, but is there anything in particular I should try and find?

Cheers for the help guys.
