TricksEditThorns - The signature trick of the Thornier Road. Thorns take the shape of long, thin rods of wind with pointed tips. Although Ringo doesn't consider them very powerful, she is capable of firing many of them very quickly, making them quite formidable.
Infinite Chain: Turquoise Thornier - Ringo's Infinity Atmosphere. To activate it, Ringo has to deactivate her Regalia briefly and let it charge. Once the charge is complete, she begins to rotate rapidly, firing Thorns indiscriminately and damaging herself as well as her opponent. While the trick's effects are not immediately clear, it was shown to be powerful enough to blow away the Wind Regalia's Infinity Atmosphere and inflict serious damage on the surroundings.
Thorn Arrow: The Keeper draws the bowstring of the Thorn Regalia's bow and releases thorny arrow-like projectiles. The arrow is able to easily pierce a person.
