Benkei

Benkei is aggressive, playful and fiercely loyal to Yoshitsune. Her panther imagery suits a fighting style based on sudden aggression and physical confidence, but she is not simply Trident's muscle.

When working with Kogarasumaru, Benkei shows a patient and nurturing side as a trainer. She understands how to push inexperienced riders without treating them as disposable subordinates.

Her loyalty to Trident runs extremely deep. The destruction of the organization and Yoshitsune's loss leave Benkei emotionally devastated, although she continues moving forward because completing her responsibilities matters more to her than displaying her grief.

Benkei is an A-Class Storm Rider who follows the Over Road. Although she does not possess Yoshitsune's Rumble King title, she can fight King-class opponents and use the Road's manipulation of air pressure both offensively and defensively.

Her principal weapon is Panther Corsa, a long metal staff with panther-head fittings. The heads conceal A-T wheels that can deploy during combat, allowing Benkei to use the weapon for propulsion, striking and maneuvering.

A blade is concealed within Panther Corsa's handle. Benkei is also skilled enough to ride effectively on a single Air Treck, demonstrating exceptional balance and adaptation.

She proves capable of confronting Om, Sleeping Forest's Water Queen. With assistance from Kazuma Mikura, Benkei overcomes Om despite the latter's King-level abilities.

Benkei appears with Trident when Ikki enters Kansai and becomes involved with Yoshitsune. Once cooperation is established, she serves as an important link between Trident and Kogarasumaru.

During Ikki's hospitalization, Benkei works as Kogarasumaru's trainer and temporary additional member. Her experience gives the younger team access to an A-Class rider accustomed to operating under an established King.

Genesis later attacks Osaka and destroys Trident's organized resistance. Benkei becomes the sole survivor of the decisive battle after cutting off her own trapped right leg with Panther Corsa's hidden blade. She carries Yoshitsune's bloodied Ram Jet Regalia back to Kogarasumaru before finally allowing herself to break down.

Benkei later joins the assault against Genesis and takes Nike's foot in retaliation for the destruction of Trident and the loss of her own leg.

Yoshitsune is Benkei's leader and closest companion. She serves as his second-in-command with absolute loyalty. After Yoshitsune is killed during Genesis's attack on Osaka, Benkei carries his Regalia to Kogarasumaru and continues fighting in his memory.

Itsuki Minami and his teammates receive Benkei's training and assistance after Trident becomes their ally.

Om is Benkei's King-class opponent during a Parts War. Benkei defeats her with help from Kazuma Mikura.

Kazuma Mikura supports Benkei during her fight with Om and later fights alongside her in the wider conflict.

Nike Takeuchi becomes a target of Benkei's revenge after Genesis destroys Trident. She later cuts off his foot before he attacks Kazu.
