Kapitel 157: Changes Welcomed by 157

Reiger's path of trial was longer than he had imagined, and even more horrifying than others had imagined.

After persisting in the courtyard for seven days, Reiger finally collapsed for the first time.

Rengoku Kyoujurou, who habitually checked in on him, was the first to discover Reiger collapsed in the courtyard and hurriedly carried him back to his room and called for a doctor.

The doctor called by Rengoku Kyoujurou was none other than the Insect Pillar, Kochou Shinobu.

In addition to being a swordsman, Kochou Shinobu was also a Pharmacist who excelled in pharmacology. She had also established a treatment facility called "The Butterfly House" within the Demon Slayer Corps, which housed some nursing staff without swordsmanship talent, specifically to provide wounded members with medical treatment and rehabilitation.
