[Kamen Rider] I Must Hold a Huge Cannon Ceremony Right Now!

A Knight Rider fan lets loose, trying out a chaotic protagonist for the first time.

All the original-series Riders in this story are treated as the heroine's secret identities, and any OOC behavior is considered a difference in how she plays the roles.

The heroine has no romantic pairing, though there are original characters who do.

Since it's unclear whether readers who aren't Knight Rider fans will be following along, tokusatsu references and specialized terms will be explained.

The title, "Big Gun," refers to the D.G.P. in Kamen Rider Geats. It's a Rider battle game run by people from the future, and the winner gets to create the world of their wishes.

//////////////////Synopsis/////////////////////

As a Knight Rider fan, when a System sprite showed up asking her to save the world, Mizushima Harui agreed without hesitation.

But then she saw the people on whom another world's fate depended:

A handsome, inexplicably narcissistic playboy protagonist who seemed bewitched whenever he saw a beautiful woman;

A wealthy young lady heroine hopelessly in love with the villain, a romance-obsessed fool who couldn't tell right from wrong and acted like a lovesick lapdog;

A mysterious male transmigrator, self-important and contemptuous of everyone, who'd say, "I don't eat beef";

A terminally ill female thief who stole from others and brazenly livestreamed it;

A lovesick, psychotic male AI who was so devoted to its master it seemed to have a masochistic streak;

A queen who left everything to her elders, then called her own self-indulgent lifestyle "going incognito";

And plenty more weirdos besides.

Mizushima Harui: ?

"This isn't an ordinary world anymore. We need to hit it hard," Mizushima Harui said gravely. "I have to put on a Desire Grand Prix right now!"

"Didn't you say Knight Rider fans are all full of justice and responsibility?!" the System cried in dismay.

"You clearly haven't seen much," Mizushima Harui said scornfully. "Knight Rider fans include, but aren't limited to, plot lovers, power-scaling fans, character fans, scriptwriter fans, suit-actor fans, actor fans, magnetic-field nutjobs, bloodthirsty viewers, and chaotic troublemakers who just want to have fun..."

She paused for breath.

"But! We've been righteous, deranged, crazy, and downright absurd. The one thing we haven't been is this pathetic!"

"How are we supposed to save the world with a bunch of clowns like these?! We have to hit them hard!"

She would create heroes for this world!

Theme: Anyone can become a hero.
