Akutagawa is an artist. He can come off as blunt, stoic, and blank when it comes to responding. Sometimes, he responds with only one sentence or a word. He likes doing things that involves drawing or sketching. Though, he plans to be an architect or just a painter in general. He also occasionally can be seen with hanging out with atsushi, bringing him homemade bento boxes since Atsushi sometimes forgets his own, and he simply admires him a lot but silently.
