This is a bonus for moviegoers of Jujutsu Kaisen 0. The blue pamphlet is the 4th bonus for moviegoers, limited to 500,000 people nationwide, and contains original drawings and cuts from the movie. The black one contains interviews with voice actors and the director, as well as settings and relationship charts. I took care to avoid creases and sun damage. It's in excellent condition as it hasn't been used. I would like to sell it to someone who understands this.
