In One Piece chapter 1137, fans finally learn the name of the Devil Fruit Gunko uses in her battle against Loki. This power is called the Aro Aro no Mi, a Devil Fruit with a unique ability that combines arrow symbols with motion control.
Although details about this power remain limited, the chapter reveals enough for fans to understand how it works and its impressive potential.
The name Aro Aro no Mi comes from “Arrow”

Like many Devil Fruits in One Piece, the name Aro Aro no Mi directly reflects its ability.
“Aro” is derived from the English word “Arrow,” fitting perfectly since all of Gunko’s skills revolve around arrow symbols that appear constantly during combat.
This is what sets this Devil Fruit apart from many previous Paramecia-type powers.
A Paramecia-type Devil Fruit that creates arrow-shaped ribbons

Confirmed as a Paramecia-type, the Aro Aro no Mi allows its user to create and control ribbons shaped like arrows. These ribbons can float in the air and be remotely manipulated by Gunko’s hand movements.
They are not just simple “arrows” for attacking, they act like extended arms. Gunko can wrap them around opponents to restrain them or even lift victims into the air.
This flexible control makes the Aro Aro no Mi a power that is both offensive and highly effective for battlefield control.
Can transform into armor and guide attacks

Another notable feature is Gunko’s ability to wrap the arrow ribbons around her hands and feet, creating armor or large weapons for close combat.
This enhances the power of her punches and kicks, making them especially effective against giant-sized opponents.
Even more impressive, the direction of her attacks seems to follow the arrows’ pointing direction, allowing Gunko to launch strikes with unpredictable trajectories. However, in theory, if an opponent moves quickly enough before the attack completes, they might still dodge.
Arrows can pierce and pin down foes

Beyond controlling and boosting melee power, these ribbons also serve as sharp projectiles.
In chapter 1137, Gunko uses them to pierce through beasts surrounding Loki. Moreover, the arrows can pin targets to the ground, completely immobilizing them.
This shows that the Aro Aro no Mi is not only strong in control but also delivers significant direct damage.
Striking similarities to Imu’s power

Fans have taken special note of the similarities between the Aro Aro no Mi and the power Imu used to kill Cobra.
Imu’s attack also took the form of an arrow piercing straight through the target’s body. Additionally, when Gunko activates her power, black flames appear around her, an effect previously seen with Imu and the Five Elders.
There is currently no official confirmation linking these two powers.
