Ep. 18: Seiryu si Naga Biru menghadapi kelompok tersebut sementara Hiei mengalahkannya dan pemimpinnya menargetkan Keiko.
As the four travel deeper within the castle, Seiryu, the third Saint Beast, appears. When Byakko weakly arrives and asks for Seiryu's help in fighting against the quartet, Seiryu freezes and shatters him to death after declaring him a failure and a disgrace to the Four Saint Beasts. Hiei chooses to battle Seiryu afterward. Although Seiryu seems to have the advantage, Hiei reveals that he has been merely toying with him, and easily reverses all of his ice attacks. As Seriyu attempts to respond, Hiei cuts him down with his sword. Meanwhile, the leader of the Saint Beasts learns about Yusuke's relationship with Keiko and decides to target her with the Makai-infested civilians in an attempt to weaken Yusuke's determination to stop him from carrying out his plan.
