There was no doubt about it.
Humans don't grow fluffy white tails.
When characteristics belonging to beasts appear on humans, these creatures usually have another exclusive name - beastmen.
No wonder, from the strange name "Animal Gang", to Lisa's description of their monstrous strength from an outsider's perspective, and finally their displays of not being very smart - when these elements were put together, Reji actually had a vague feeling early on.
And now, with the white-haired woman "revealing her tail", it undoubtedly put the final nail in the coffin for this conclusion.
So after elves, the next new race to "descend" upon this world was...beastmen?
In the first playthrough of the game, there were only two races in the world - humans and demons.
