Jotaro Kujo is very quiet, stern, and some may say rather rude. He is very closed off, and seen as somewhat of a delinquent by his peers. He only talks to people if he sees them as worth his time, but this doesn't necessarily come with a sense of arrogance. Deep down, he is a hero who fights for whats right. He also seems to lack just about any empathy on the outside, but in reality he is only stubborn. He is also 17. If it comes down to it, he will express his empathy towards others.
