Murata possesses plain and unremarkable features; straight jet-black hair parted down the middle, similarly colored eyes and possesses an athletic build.
Not much is known about Murata, however, he does not like it when a hunter of lower rank chastises him. He is somewhat timid, however he does seem braver than most, continuing to fight atop Natagumo Mountain even after his entire group was wiped out.
Murata's history before his mission to Natagumo Mountain is unknown, however he, much like most of the first Demon Slayers sent to the mountain, was fairly low in rank.
Murata was in the same final selection as Sabito and Giyu. Despite that, he claims to have many differences with him.
Having been sent to Natagumo Mountain to exterminate the Demons living there, Murata is approached by Tanjiro Kamado and Inosuke Hashibira. He explains to them how the Demon Slayers sent to the area started killing each other as soon as they arrived. He is then startled by the arrival of another group of these puppet soldiers. Locked in combat with one of them, he is saved from a sneak attack by his two juniors, hastily introducing himself while resuming his fight. The senior officer urges them to leave the puppet soldiers to him, despite Inosuke's insults, warning them of the possibility of stronger controlled people up ahead.
Some time later, Murata is ambushed by the Daughter Spider Demon and wrapped up in her Acid Cocoon technique, which he couldn't cut out of. He is freed by the Insect Hashira, Shinobu Kocho, and asked whether it was a good decision to have let the Older Sister Demon live. The Hashira explains that she had actually used Wisteria poison to kill their opponent, before pointing out his lack of clothes, much to Murata's embarrassment.
Murata visits Tanjiro, Inosuke, and Zenitsu Agatsuma at the Butterfly Mansion. He complains about the hellish situation of being summoned to the Hashira Meeting to report what had happened on Natugumo Mountain, but hastily leaves when Shinobu comes to visit.
Murata meets Tanjiro and Inosuke during his training with Gyomei Himejima. He points out how harsh training is, and is impressed by how strong the Hashira are.
It is unknown if he passed Himejima's training or gave up.
Overall Abilities: Although not on par with the likes of Tanjiro or Inosuke, Murata's prowess is superior to that of his squad, as evidenced by being its only survivor (albeit with the aid of multiple characters). His assistance in dealing with his manipulated comrades was vital in buying time for Tanjiro and Inosuke to defeat the Mother Spider Demon. Since the puppets had their powers augmented because of the Demon's Blood Demon Art, his ability to hold them back was a testament of his above average performance. He was also able to reach the last stage in the Hashira training curriculum, which hardly any members could do.
