Chapter 187

Innocent Person (なる) is the one hundred and eighty seventh chapter of Koyoharu Gotōge's Kimetsu no Yaiba.

Summary
After crossing paths with Muzan, Yoriichi immediately senses his violent intent, comparing it to "magma erupting from a volcano." He reveals that Muzan was the first to instigate the confrontation after stating his disinterest in swordsmen that utilize breathing techniques. As he lunged towards Yoriichi, it became adamant that Muzan possessed great skill and speed. It was the first time that Yoriichi had sensed a presence of danger.

Using his See-Through ability, Yoriichi was able to distinct Muzan's anatomical difference that set him apart, he had a total of seven hearts and five brains. However despite his immense skill, Yoriichi was still able to successfully complete his sword forms and demobilizes Muzan. (As the flashback progresses at this point, Tanjiro's conscious within Sumiyoshi's body realizes that Yoriichi had mastered the unknown 13th form and eagerly listens.)

Despite trying to regenerate his body, Muzan becomes stunned and is forced to hold his head in place to keep it from falling off. Yoriichi realizes that the immense amount of damage was caused by the red blade that the wielded. He question's what Muzan's value of life was, hoping to seek and answer but only received a glare of anger.

Yoriichi's attention is then drawn to the young demon girl, —revealed to be Tamayo—, travelling with Muzan. He immediately notices her eyes staring directly at Muzan, not with a look of concern, but with a look of hope as he sat there with a severed head.

Before he began dealing with her, Yoriichi began to approach Muzan in order to finish him off. However as he walked towards him, the sounds of teeth grinding grew louder in volume until Muzan's body burst into 1,800 pieces. Caught off guard by the sudden escape, Yoriichi reveals that he was only able to obliterate 1,500 of the pieces, allowing some of him to escape.

Tamayo collapses on the floor and begins to weep while tearing out her hair.
