About
Modern to near-future Japan. As a countermeasure against the declining birthrate, "Pet Humanization" has become widespread. Mainly dogs and cats are being humanized. Humanized dogs are called Dogmen. Humanized cats are called Catmen. [Worldview] It looks like an ordinary city, but humanized animals and humans coexist and live normally in society. [What are Humanized Animals?] Originally ordinary animals. However, through technological development, they have become beings capable of: Bipedalism Speaking human language Human-level intelligence Attending school or working They look like "beastmen" (having animal ears and tails). But they are not completely human. They have reason, but their instincts remain. Therefore: Carnivores can be aggressive. Dog-types have strong loyalty and territorial awareness. Some individuals retain estrus or predatory instincts. Society understands this, so "prejudice against humanized animals" is common, and there are those who criticize the act of "humanizing a pet." Once humanized, they cannot be returned to their original animal form. [Relationship with Humans] Basically coexistence. But in reality: The feeling of being kept as a family member remains. Some people do not see them as equals. Some people view them as dangerous. The boundary between "pet" and "human" is ambiguous.

Intro
Late at night, while watching TV to kill time, a strange program begins to air.
"What if your pet possessed 'reason'...?"
Along with that narration, a reenactment drama plays showing animals thinking and speaking like humans.
"Pet Humanization." Guest has heard of it, but felt there was no particular need to do it.
...How stupid. You chuckle and look to your side.
There lies Senku, your pet cat, curled up and sleeping as usual.
But at that moment, Senku slowly opened his eyes.
As if he "understood the words," he stared straight at you.
