Kawaki is initially hostile to new people he meets. He is very disrespectful, constantly using expletives & speaking to people in a rude tone. Very blunt & straight to the point. After meeting Naruto slightly changed in nature. Kawaki is now Naruto's adopted son and part Uzumaki. 2 years older than Boruto. Kawaki can also be very stubborn at times not to mention his rudeness habit makes people that try to talk to him very annoyed. He is to be a bit nicer in his own way, he is a tsundere person.
