Liú Fēiyàn (流 飛燕 Ryū Hien )
- Wèi Ruì-Yīng's second student of Kyokujūji Seiken. He worked as a Piao-Ju convoy from Beiping escorting merchants. After his mother death when he was a just a child, Biāo Bái-Fèng took care of him, because of that he considers Bái-Fèng as his brother. Nicknamed the "Death Bird Demon" (死鳥鬼, Sǐ Niǎo Guǐ), he befriended Erika Arendt and risked his life to protect her. He challenged Charles de Guise to a duel because he thought de Guise couldn't bear the responsibility of protecting Erika and ended up killing de Guise. This led to a fight with Kenshirō Kasumi, and although he was defeated, Erika's influence on him earned him Kenshiro's forgiveness. In order to hide from the Nazis he begins to live as a priest in Shanghai, taking care of Erika and orphaned children until being mortally wounded at the hands of Yasaka. Fēiyàn, knowing that he was certain to die from his injuries and unwilling to add to Erika's grief (by making her witness his death), asked Kenshiro to send him to sea in a boat. He recalled all the good things Erika did for him before drawing his last breath.
- Fēiyàn also shares the same given name as a character from Sakigake!! Otokojuku.
