GS Mikami: Gokuraku Daisakusen!!

Same motive of urban fantasy, a spiritual warrior who fights against evil. 

Both series share the same styles of mixing horror with comedy. While Nube is the darker of the two with the story being centered on a demonic clown, the Mikami movie does offer more variety & action with the inclusion of zombies & Nosferatu. They're good movies for their respective animes. 

Both series have the same blend of comedy & horror. The final episode for Hell Teacher Nube OVA definitely has the feel of a movie with its updated animation & more action oriented plot. Ghost Sweeper Mikami Movie is not as dark as Nube but offers comedy& a battle against some zombies & Nosferatu. 

Both series deal with demons & supernatural enemies. Mikami offers more comedy while Hakusho provides more action.  

These anime as a whole have different themes with Slayers being fantasy & Mikami being supernatural, however they do share very similar leading ladies & overall humorous cast of characters. I recommended this movie out of all the other Slayers films as this is the only feature where all of the main characters are present. Mikami's plot revolves around Nosferatu while Slayers is more comedy based with Octopus' invasion. Ghost Sweeper Mikami is dark but offers the same humor as The Slayers.
