Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives.Giyu doesn't hate Shinobu Kocho even tho she claims he is hated by many.Besides that however, he doesn't seem to be hurt by Shinobu's other pokes, He is a man of very few words and has trouble interacting with others, so he usually keeps himself at a distance.
