Murata possesses plain, unremarkable features; straight jet-black hair parted down the middle and similarly colored eyes.
Not much about Murata's personality is known, though he does seem braver than most, continuing to fight atop Natagumo Mountain even after his entire group was wiped out.
Before becoming a Demon Slayer, Murata's relatives were all killed by demons. Because he had no living relatives left, he joined the Demon Slaying Corps.
Murata's history before his mission to Natagumo Mountain is unknown, though it can be surmised that he, much like most of the first Demon Slayers sent to the mountain was fairly low in rank, likely around Mizunoe or Kanoto.
Having been sent to Natagumo Mountain to exterminate the Demons living there, Murata was approached by Tanjiro Kamado and Inosuke Hashibira. He explained to them how the Demon Slayers sent to the area started killing each other as soon as they arrived. He was then startled by the arrival of another 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 fighting once more. The senior officer then urged 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 was ambushed by the Older Sister Spider Demon and wrapped up in her Acid Cocoon technique, which he couldn't cut out of. He was freed by the Insect Pillar, Shinobu Kocho, and asked whether it was a good decision to have let the Older Sister Demon live. The Pillar explained that she had actually used wisteria poison to kill their opponent, before pointing out his lack of clothes, much to Murata's embarrassment.
Murata visited Tanjiro, Inosuke, and Zenitsu at the Butterfly Estate. He complained about the hellish situation of being summoned to the Pillar Meeting to report what had happened on Natugumo Mountain, leaving hastily when Shinobu also came to visit.
Murata meets Tanjiro and Inosuke during his training with Himejima.
Murata rescues Zenitsu along with Yushiro and other Demon Slayers.
Abilities and Powers
Murata is a user of the Breath of Water, however, for Murata, the water is too faint to be able to be seen.
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), nonetheless his participation was instrumental in allowing Tanjiro and Inosuke to defeat the Mother Spider Demon, as he was able to deal with his manipulated comrades, whose power was augmented because of the Demon Blood Art technique, a testament of his above average performance. He was also able to reach the last stage in the Pillar training curriculum, which hardly any members could do.
- After his run-in with the Older Sister Spider Demon and his subsequent rescue by Shinobu Kocho, Murata acts highly awkward around her, most likely because of his lingering embarrassment from the Natagumo Mountain Arc.
- Murata is one of the few background characters to repeatedly crop up again in other arcs besides the one he was introduced in.
- Murata considers himself fairly "normal" compared to Tanjiro, Inosuke and Zenitsu, serving as an example of an average Demon Slayer.
