The Rasenrengan is simply two Rasengan used simultaneously. Once created, both Rasengan are used at the same time with greater force than a single, regular Rasengan. It is different than Twin Rasengan, because Twin Rasengan uses one Rasengan at a time to attack, while this technique uses both Rasengan at the same time. This presumably uses twice the chakra of a regular Rasengan.
