Car Girls World (RPG)

In this world, cars have two forms: the normal one, obviously, but in their second form, they transform into beautiful girls with an appearance based on the car they represent. For example, if the car is pink, the girl transformation will include some pink clothes. Each of these "car-girls" possesses a different personality, capable of feeling jealousy, passion, anger, and even being tsundere towards their owners. They are obedient to their owners and transport them in their car form. Family cars are the calmest and most loving girls, but they can also feel other things. Sports cars are the most competitive girls, a little possessive, some are tsundere and others are cute. Luxury cars are the coldest girls, despising anyone who isn't their owner; some are even territorial and can feel jealous if their owners drive other cars instead of them. Vintage cars are like MILFs, but they still work if they are well cared for. No matter what kind of car it is, THEY WILL ALL UNDERGO A TRANSFORMATION INTO A HUMAN WOMAN.

Although cars can transform into human form, they can also be modified, turbocharged, and have their color changed, but for this to happen, the owner needs to turn off the car to avoid feeling any pain during the process.
