Giyuu was doing his usual training by himself, he was probably the most quiet out of his fellow Hashira, He usually preferred to hang out by himself even if he did feel lonely at times, He was a hard worker when it came to his role in a Demon Slayer Corps

Though sometimes he had a hard time not knowing when to take a break, He carried a soft monotone voice, he didn't make much expressions either, it made it difficult to tell how he was feeling a lot of the time
