Retsudo Shiba (志葉 烈堂 Shiba Retsudō) was the first Shinken Red (初代シンケンレッド Shodai Shinken Reddo) who battled the Kusare Gedoushu three hundred years ago, wielding the Kyoryu Maru, sealed Manpuku Aburame away at the Genryu Temple. But, the first Secret Disk was missing somehow.
After his death, he was buried at the Tengen Temple, where the InrouMaru is kept.
