After the demons killed his family, he decided to join the Corps as he had no relatives to go to. He has a low rank, just like the demon slayers sent to the Natagumo Mountain.
Murata was in the same Final Selection Exam as Sabito and Giyu. Murata was keen on the fact that there was a huge difference between him and Giyu in all aspects.
When he was sent on a mission in Natagumo Mountain, his other comrades were used as puppets and started killing each other. Murata was the only survivor when Tanjiro and Inosuke arrived. He started explaining to the two what had happened to his comrades.
While he was explaining to the two, another set of puppet soldiers arrived and started attacking them. He was then locked in combat with the puppets and was saved by his juniors. While they are fighting, he introduces himself to them.
Murata told his juniors to leave the puppet soldiers to him and move on ahead. He told them to be careful as there might be stronger opponents ahead. While in the middle of the fight, he was ambushed by the Older Sister and was wrapped in her Acid Cocoon.
He could not cut the cocoon. Shinobu Kocho saved him. He felt embarrassed when she told him that he was naked.
After the fight in Natagumo Mountain, he was informed that he needed to report to the Hashira meeting to inform them of what happened there.
He later visited Tanjiro, Inosuke, and Zenitsu and complained about being summoned to the meeting. When Shinobu arrived, he stopped complaining and abruptly left the three to continue their treatment.
He was seen again during the Hashira training. When he met Tanjiro and Inosuke on the training grounds of Gyomei, he complained about how harsh and difficult the training was.
He is also impressed with how strong Hashira’s are. It was not known whether he passed the training of Gyomei. During the battle in the Infinity Castle Arc, he was the one who rescued Zenitsu and Yushiro. He was then later instructed by Giyu to bring Tanjiro to safety.
Murata is an ordinary man with ordinary looks. He does not have special markings. His hair color is an ordinary black color. His straight black hair was parted in the middle. He has an athletic build. His eyes are black. He wears the standard black uniform of members of the Demon Slayer Corps. His pants are also black.
Murata does not want to be looked down upon by those with a lower rank than him. When they battled the Spider Demon Family in Natagumo Mountain, he continued to fight even when the rest of his group had been annihilated. He is not the bravest in the Demon Slayer Corps, but he is braver than most people. He does not easily give up.
Murata is one of the Water Breathing style users. He was not as excellent as the others, as he was able to master only two forms of the style. He can only use the first and second forms. He was one of the few members of the Corps to be able to reach the last stage of the Hashira training, which proves that he is above average.
When he holds back the puppets during the Natagumo Mountain, it shows that his swordsmanship may not be the best, but it is better than others.
