Reincarnated Into My Own Light Novel (And Everything's Wrong?!)

Ryu Tanaka was a painfully average light novel author with one utterly forgettable fantasy series: "Crimson Blade Princess of the Sacred Elf Wars: Destiny Dance Omega." It sold three copies, and one of them was to his mom. But after a freak accident involving his cat and a third-story window, Ryu wakes up in the world of his own book - as the heroine-turned-hero Kris Veleblade.

There's just one problem.

Nothing is how he wrote it.

His sweet little sister? Now a goth punk tsundere with a sword addiction.
The noble princess? She rules a kingdom of kink and flirts like it's her royal duty.
The brave knight? Rewritten as a violent halfling thief with world domination issues.
The Demon Lord? Now a chill auntie who gives great life advice and makes the most delectable scones.
And the villain? A 4'11" holy man named Pope Benefits who wants to exterminate everything that isn't human.

Oh, and the god who reincarnated him? He's mad he wasn't in the original story and is now making revisions out of spite.

Armed with meta knowledge, a mentally unstable hobo, and absolutely no idea what's going on, Kris must survive a plot that's unraveling faster than his author career ever did.

Can Kris rewrite his destiny in a world that's already been rewritten? Or will his own characters kill him first? One this is for sure. His life has been turned upside down.
