Saki the Succubus Hungers Tonight Vol. 4 (manga)

Saki is left out in the cold when rival succubus Mami confesses her feelings for Renta first. And then, even worse, Saki gets left out in the rain. Stuck outside in a freak rainstorm and soaked to the bone, she chases after Renta to set the record straight and confess her own love. She's in for a surprise when Renta pulls her into the closest building to escape the downpour-and it turns out to be a love hotel!
