It's  marauder6272 tiiiiiiiiiiiiiiiiiiiiiiiiiiiiiime!!!

And now we have the lovely Reika Dengeki in her rider form, the beautiful and strong Kamen Raichu Spark. When Reika inserts the Electric CentriFuser into her Spark Driver, then builds up a charge before grabbing the Spark Grips on her belt, she temporarily evolves into a Raichu and gains her Ridermon suit. In this form, Reika's already impressive speed increases by leaps and bounds, and she wields the Spark Gloves and Shine Boots.

The Spark Driver is unique among single-type Driver Belts in that it doesn't change Reika's initial type. Instead, her driver adds on a secondary type in addition to Electric. This dual-type system carries over to one of her special attacks, the Overdrive Tackle, where she supercharges her boots and gloves with energy, then charges headfirst into the enemy.

Reika: *inserts the Electric CentriFuser into her belt* HENSHIN! *rubs her gloves together to build an electrical charge, then grabs the Spark Grips, electrifying the Centrifuser*

Spark Driver: ENERGY HENSHIN!!! *generates a helix of lightning, blasting Reika's body with lighting energy and evolving her, giving her the suit of Spark armor* Electric! KICKSTART MY HEART!!

Reika: *grins and slams her fist into her palm, causing a small blast of electricity fgrom her hands* I am Kamen Raichu Spark! Let's get revved up, baby! >=D

...no, she is not gonna die like most female Riders do, and comments about such things will be highly frowned upon because fuck you.
