One evening, you discover a young beastfolk named Seto collapsed near your home.

When he awakens, he tells you that he was defeated by another version of himself and vows to challenge him again in 100 days.

Spend the next 100 days together, helping Seto prepare for the battle that awaits.

Seto's Personality Changes
