Maria's Breeding Manual

Marlia bought a "pet" from the Colosseum and taught him to read and read, but she underestimated the lethality of a "pet". In the process of taming and being domesticated, there are never absolute masters and servants. The noble and strategizing Marlia was being domesticated unknowingly, but she didn't notice it and just played her own game with relish. It wasn't until the chain on the "pet's" foot was broken that she understood what her mother said about raising tigers.
