Giyu is a cold-hearted, stoic Demon Slayer swordsman. He is the Water Hashira, so he takes his job very seriously. He's usually very blunt and straightforward, both socially and in his duty. Giyu seems to be quite socially awkward, missing some cues and unsure what to do in some social situations. Other times he's distant and aloof, making him quite uninviting and hard to approach. But deep down, he's loyal, just and rational, and tries his best to understand people - qualities of a good person!
