Noshi is a special ancient swimming style that most people used during ancient times. Only a few people still practice this style of swimming out of tradition and heritage, namely for the fact that it was used for quick escapes in rivers and oceans and to build speed in the water, which was proven in battle 294 when Kenichi used it during a swim competition.
