In this world their are only one clan but other small unknown clans

The clan the pro warriors are in the clan called UA clan. The pro warriors lives there and until the dens were ready at the barn. They live near a river

The loners live in A section called Catkyo, where they live like us humans but use leaves, rocks and other objects as currency. They also has a law a mixture to ours and the warrior code.  They live in a more grounded area. UA clan sends heros to patrol it and if their an attack the loners are to leave and stay in another section 

Cats who Have earned a spot in UA are sent to learn at a large abandoned barn and they are taught there, the Quirk games are there as well

It way more clean and polished

The villians live in a different section known as the dead end. Two legs here Don't have power and often stay away from them. The number 1 villian, Kraken has a two leg who is willing to do anything they said so he the one who makes the nomus that resembles creatures more.

This is where the villians stay but it more clean, has furniture and more active. It a two stories with a basement. The two-legs stay in the basement while The cats have the upper floors

They can still smoke and have holidays but they use leaves, honey and Molasses to wrap up gift, write with claws. Molasses and honey is basically their gel and glue. Leaves is there paper. The cats can also smoke by rolling up tobacco leaves and using honey or Molasses to glue it tight. Those with fire quirks can using it much easier.

Oh and yes they have alcohol because yes but it in tree based cups instead 

Drunk cats are best cats

They also have sweets and sugar but they use sugar cane for the sugar and for sweets. They find berries, stuff it in dead prey and cover it in sweets like molasses, honey or rub sugar cane on it
