Looks like there are some interesting plans for the fourth Hayate anime series. April's Hayate the Combat Butler: Cuties will feature a different path, dedicated to a different heroine in each episode. Furthermore, each ep will have its own end theme.
Shizuka Itou sings the opening "Haru Ulala♥ Love yo Koi!" ( Spring ulala ♥ Come, Love!)
The staff from Hayate the Combat Butler: Can not Take My Eyes Off You return for the new series.
