Rebellion Concerto (リベリオンコンチェルト - Riberion Concheruto) is Ryōna's Ultimate Ninja Art in Senran Kagura: Shinovi Versus and Senran Kagura: Estival Versus. It requires 5 Ninja Art scrolls to use.
Overview[]
Shinovi Versus[]

Ryōna skates around like a figure skater, lunging, jumping, and twirling as she fires her guns wildly in all directions. For the finale, she leaps into a spinning pirouette, and lands on the ground causing a geyser of ice shards rise up.
This attack has range and can be moved into the desired direction, allowing Ryona to keep in pursuit after enemies that may stray. If caught in the fray, enemies will be frozen and will be devastated by the barrage of bullets in every direction.
Estival Versus[]

This attack retains most of its uniform action from the original. However, there are some notable differences that make this technique much more powerful. As before, Ryōna skates about, lunging, jumping, and twirling as she fires her guns wildly in all directions. Only now bullets from her attacks start to burn and freeze enemies on contact. For this finale, she releases large bursts from her gun, causing large ice pillars to shoot up from the ground, and an ice statue of her guardian animal shoots up and presents itself center stage.
(Ryōna becomes able to use it after reaching Level 12.)
