So the 2 movies these are based off of are Ponyo and My Neighbour Totoro.

 First up is Ponyo!

First is Soke based off of Sosuke. Ever since he was a little boy he was very responsible and had a love for boats due to his dad being a captain. He loves the ocean and wants to lean as much as he can about it. He's very loving and caring like his mum taught him but sometimes he can have a very one track mind. 

Next is Lisa, Soke's mother. She's a very caring and loving individual. She helps the elderly to make sure they're able to be safe and cared for. She's also a very loving mother however, this version is her as a teen of course. She is also very stubborn when pissed off so if she does have a partner then they may need to calm her down to change her mind. She cares a lot for others and especially her "younger brother"

MY NEIGHBOUR TOTORO

Meiy (Based off of Mei) is the youngest in her family with her mother being sick and her dad working to the bone, all she had left was her big sister to look after her. They fight but always make up in the end. Meiy is childish and looks for adventure, clinging to those she loves so she won't alone. She also knows she can mess up and apologises for it if she does. She also loves the idea of spirits and ghosts and believes there may be a spirit that lives under her house which only she sees (Which is actually a lusus that had found it's way to earth, not that she knew it.)

Saki (Based off of Satsuki) is Meiy's older sister. When their parents passed away, she was the one who took on all the responsibility. She's hard working and looks after her sister. It sometimes leads to fights but they make up for it in the end. Saki does have some belief in mythology but doesn't like to admit it since she is generally a realist. She goes to classes which is why she doesn't hang out at home often but then that makes Meiy cling to her. She is respectful and understanding as best she could and overall just does her best each day so she can look after her younger sister and herself.
