Momiji, having won in the first round of the Festival, fights Hagun's representative, Shizuku Kurogane. At first, Momiji uses Trackless Step, to make Shizuku unable to hit her, but Shizuku counters this, by covering the arena with thin water, and sensing Momiji's movements. Shizuku then attacks Momiji with Water Prison Orb, taking her out, and winning the match. This leads to Momiji getting eliminated from the Festival.
