Ep. 8: Hiei holds Keiko hostage with the Shadow Sword, forcing Yusuke to battle him for the antidote.
Hiei, the final thief wielding the Shadow Sword, has kidnapped Keiko to obtain the Orb of Baast and the Forlorn Hope from Yusuke. The situation escalates when Yusuke and Botan discover that Hiei struck Keiko with the sword, causing her to slowly transform into a demon. Botan utilizes her spiritual energy to halt the change, while Yusuke realizes he must defeat Hiei to retrieve the antidote sealed within the sword's hilt. Hiei employs the Jagan eye to gain superior perception, making the fight extremely challenging for Yusuke. Kurama intervenes to aid Yusuke in combat and assist Botan in protecting Keiko. Yusuke ultimately defeats Hiei by firing his Spirit Gun off the Forlorn Hope to strike his blind spot. The artifacts are returned to the Spirit World, and Keiko is restored to her normal human state after receiving the antidote.
