Aikido and Ju Jutsu. Sounds like Hapkido to me. Get the circular throws and locks. Get strikes and kicks. The way we train Hapkido, once you get the throw or takedown we takeit to the ground and try for a submission. Hapkido and BJJ blend quite well. Learning this way, you dont always have to go to the ground(multiple attackers) but are competent if you have to.
