Oh My Goddess! Vol 19

From the Dark Horse edition

College life is never easy... All right, sometimes it is, but never at Nekomi Tech! No sooner do Keiichi and Belldandy solve the mystery of the Phantom Racer then they get entangled in the schemes of Professor Morozumi. Better known on campus as "Dr. Moreau" for his obsession with making machines walk on two legs, this mad scientist will stop at nothing to pursue his dream... including kidnapping Banpei's "girlfriend," the Welcome Robot!
