From Sevan Seas:
Before Glenn Litbeit opened his own clinic, he was just a med student in an academy full of monsters! Take a trip back through time in this prequel volume about young Glenn’s trainee days at the lab run by his upperclassmen Sapphee and Lime. Dog-headed girls, hypersensitive marionettes, amorous silkworm-ladies and more with such tantalizing adventures in consultation under his belt, it’s no wonder Glenn became the doctoral sensation he did.
