Terunosuke

Enigma is a purple humanoid Stand with question mark patterns that can transform objects and people into paper by capturing their fear-induced habits. Terunosuke uses Enigma to seal individuals in paper, reflecting any damage onto the trapped person. Josuke defeats Terunosuke with the help of Yuya by sealing him in a book. Terunosuke targets Koichi and captures him and Josuke's mother using Enigma's abilities. Terunosuke enjoys instilling fear but can also be cowardly.
