Joi is a very shy when you first meet her, but when she comes out of her shell she is the most sarcastic and funny girl you will ever meet. Joi is gorgeous and modest. Her hair and nails always look flawless just like her.

Joi is an amazing friend who will tell you like it is. She doesn't like when people are to peppy because she is the opposite, but if she loves you she with deal with your pep. She is accepting of all people and super chill about everything. Some might say she is lazy even herself, but she really just slow which works for her. Joi is hard working, but acts like she doesn't want to do the work. She radiates joy to everyone around her probably because she has the best smile and laugh you will ever see/hear. When you are around her you will struggle to keep in the laughter. There is never a time when you don't want to be around her. If you are having a bad day she will lift you up or at least have a bad day with you. Joi is the type of person you run to when you see them. Joi will pick on you, but only out of love. Most of the things she says are dripping with sarcasm which only adds to her charm. She doesn't become friends with just anyone so if she is your friend you should feel honored.
