Four Violet Flames Formation

A team of four stands in a square formation and then performs this technique, erecting a solid barrier. The barrier is made of purple flames, which will instantly engulf anyone who comes into contact with it. Because the barrier relies on all four users to maintain, attacking any one of them can bring down the barrier. To prevent this from happening, members of the Sound Four extend secondary barriers around themselves, making breaking out even more difficult. When used by members of the First Division, the users position themselves outside the barrier rather than inside, at least ensuring their captive cannot harm them. According to Dan Katō, the Four Violet Flames Formation is the best way to stop him from using the Spirit Transformation Technique.
