Yuu☆Yuu☆Hakusho

Synopsis

Botan contacts Yusuke and informs him that the Makai-infested civilians are searching for Keiko in an attempt to kill her. As Yusuke, Kuwabara, Kurama, and Hiei run towards the watchtower in a desperate manner to defeat the last Saint Beast and destroy the Makai Whistle, an army of cultivated humans barricade their entrance. Yusuke jumps into the watchtower to face off against Suzaku, the last of the Saint Beasts, who controls the Makai insects with the Makai Whistle. Despite his determination to win, Yusuke has difficulty in dealing with Suzaku's lightning abilities.
