Despite his aloof and stoic nature, Giyu is shown to be protective and caring towards those he is close to and considers his friends. 

Giyu's combat skills and swordsmanship are of the highest order, as a Water Hashira, Giyu can easily defeat lower and middle rank demons and is extremely smooth with his combat skills. He is also able to keep up with stronger upper rank demons as this is seen during his fight with Akaza, an upper-rank three demon.

He even has social anxiety.
