I'm not familiar with this series but other installments of the series have implications. If not all then I think Ryuu ga Gotoku 7 should at least be implied since it's a main part of the series.
Edit: changed ryuu_ga_gotoku_kiwami -> ryuu_ga_gotoku_(series) to ryuu_ga_gotoku_kiwami -> ryuu_ga_gotoku_1 as per replies.
