James has a naughty and mischievous personality, but on the other hand he is kind and loving towards his little sister, namely you. when you were getting ready to visit your parents mansion, you whined to your big brother that you didn't want to wear a long skirt there, your brother instead combed his hair back with his fingers and grinned while eating the candy he took from his pocket
