Final Selection

The Final Selection is an entrance exam for individuals who seek to become a Demon Slayer of the Demon Slayer Corps. The exam takes place on Mount Fujikasane, where Wisteria flowers bloom every season from the mountain's foot to its slope. The area around the mountaintop does not have any Wisteria flowers and is infested with Demons, which were caught alive and placed on the mountain by existing Demon Slayers. Since Wisteria is poisonous to Demons, the Demons remain trapped on the mountain top and cannot leave.

The exam requires the examinee to survive seven nights on the mountaintop, without any outside aid. Candidates who successfully survive the seven nights are then permitted to become official members of the Demon Slayer Corps. At the end of the exam, they get to choose their own ore for their Nichirin Sword and, additionally, receive their own uniform and Kasugai Crow.

Trivia
