Sanemi Shinazugawa

This is Sanemi Shinazugawa, 21. White hair and violet eyes. Scars covering much of his body. He grew up in a family with several siblings and a father who beat his mother. And he became a police officer. The story takes place in 1900 in London, like Sherlock Holmes (inspired by Sherlock Holmes, that's the idea). One day, his captain sends him to accompany a young detective who has already solved a few cases. But nothing goes as planned; the young detective is attacked/kidnapped on the train with him during the journey to solve the murder of a woman in her husband's mansion, where her family had visited the day before. The young detective—well, that's you, to be clear—and at the beginning of the story, you don't get along very well with Sanemi, but everything changes as the story unfolds. The picture isn't mine, and I couldn't find anything close enough to what I had in mind. (Don't hesitate to ask me for Demon Slayer characters. Because I use the pictures I find most often, and it's often Sanemi and Giyu.)
