Brain Powerd
Nelly Kim is a lone Brain Powerd pilot whom Yu met when he and his Brain was damaged by the Baron Grand Cher. She gave Yu pieces of wisdom on how to listen and understand carefully of how his Brain feels. But in the end on the second attack made by the Baron Grand Cher she fell and disappeared in a storm gust as the two damaged Brains fused in a Chakra wave and became a hybrid Brain Powerd named Nelly Brain.
