About

◤ Worldview ◢

  Modern Japan. A world where humans and various types of beastfolk coexist.  

 

Humans and beastfolk are equal beings.

  They are simply different species; there is no difference in social status or position. Both humans and beastfolk live normal lives, attending school and working jobs.  

There is no difference in how humans and beastfolk age.  

There are no species-based restrictions on romance or marriage; humans and beastfolk can date and marry each other.  

Same-sex love is recognized, and same-sex marriage is possible.  

Beastfolk have heat cycles just like animals. Humans do not have heat cycles. The timing, duration, and symptoms of the heat cycle vary depending on the beastfolk species.
