Kamen Rider Diend

Kamen Rider Diend is a world-centric character in Kingdom Hearts: Dual Paths as well as a minor Guest in the Modern Province. His actions kickstart Phayne's campaign within this world.

In actual publications, Diend serves as a Rival to Kamen Rider Decade, a Kamen Rider created to honor previous entries in the Franchise. While Decade traverses the nine dimensions, fixing anomalies and discovering his true identity, Diend follows to steal treasures from the worlds he ends up in. He and Decade begin as bitter rivals, only to often work together. They develop a odd friendship throughout their tenure.

Story
Diend follows Decade into the Modern Province unbeknownest to his rival. After having an odd conversation with a grey-hatted figure, he sees a sushi-shop owner playing with a robotic toy of unknown origin. Seeing the toy as a treasure, he swipes the robot from it's handler, prompting the shop-owner to chase him. He doesn't get very far however, as a Remnant ambushes him and steals his transformation gun. Powerless, Diend is forced to turn to Decade, the shop owner, and now Phayne to recover his weapon, promising to return the stolen item in exchange.

The Identitis proves too much for just the four. Forced to retreat, the four lure it into a desolated area, whereupon the Shinkengers, the local superhero team, intercept the Remnant. With everyone working together, the Remnant is defeated, and all items are returned to their respective parties.

While having no prominent role during Kamai's campaign, Diend is seen watching her from a rooftop alongside the grey-hatted figure.

As a Guest
Diend participates in the first battle against the Identitis alongside Phayne, Decade, and Shinken Gold. He ends up being the weakest of the pair, simply spamming kick combos on the nearest enemy. Being a Guest, he cannot be customized, has invisible stats, cannot be defeated, and does not appear in the Pause Menu.
