I'm still developing Shining, but meanwhile here's another idea:

The Psychic Rider, Kamen Rider Psi-K!
In this world, roughly 5% of the population are Espers, humans born with psychic abilities, identifiable by a "third eye" mark on their forehead that gets more visible the more they use their powers. An Esper who loses control becomes a rampaging monster called a Psych-Over, sometimes they can be saved and returned to normal but other times the change is permanent. Because of this, Espers face widespread fear and prejudice from normal humans, and the distress this causes them raises their risk of going Psych-Over, creating a vicious cycle.

Into this conflict steps Seiko Gushiken, AKA Kamen Rider Psi-K. She's an Esper who used to work for the secretive company Core Techs, who experimented on her to enhance and refine her powers and then sent her to hunt Psych-Overs. On one such mission (the first episode), she forms a bond with an orphaned Esper girl named Mirai, who holds great psychic potential that multiple sinister forces will stop at nothing to get their hands on, including the anti-Esper hate group Braindead, extremists within the Esper rights alliance Esperanza, and her old bosses at Core Techs. All three of these groups are willing to unleash Psych-Overs for their own purposes, and I think all three of them might eventually get Kamen Riders of their own too.

The collectables are Psycards, cards themed after the Tarot major arcana that contain psychic powers extracted from Espers, a process that can possibly save someone who's gone Psych-Over but also possibly kill them. The Psycards are used to transform, summon items and activate special abilities, but unlike past card-based Riders, all Psycards are in the same style and can be used by any psychic Rider, so they could be traded or stolen back and forth between the characters, and duplicates could exist too.

I haven't developed the other Riders much, though I have a vague notion of two brothers who become the twin Kamen Riders, Egos and I-D.

And yes, the names are all driven by horrible puns XD
