When Rose breaks into a gallery to steal an emerald worth millions she trips the security alarm and is forced to stash it somewhere and what better place to do it than the local hot spring across the road. She takes up a job there to recover it the next day but unfortunately for her the R.U.C.'s elite team, Sylvia, Celica, and Accela, are taking one of their only days off at the same hot spring where the emerald is being hidden. By coincidence, Roy, Miranda, Kasha, Yuto, and Solty are also there.
