Every story needs a great evil for the hero or heroine to defeat…

The wicked stepmother who torments Cinderella.

The fearsome dragon who kidnaps the princess.

The fake rich daughter who bullies the real.

An evil demon queen hell bent on destroying the world.

Yet sometimes these villains defeat the heroes.

Agent 214 has been tasked to enter these dangerous worlds and eliminate these evil villainesses before they have the chance to win.

But why is every story a little different than what it first seems?

When other people experience a body transformation, it is inevitably either male to female or female to male.

Me? I wake up to find myself transformed into two different bodies.

Both a male body and a female body, one conscience operating two bodies, all sorts of embarrassing moments.

Walking together normally makes other people think that I am sweethearts with my other-self, such sadness.

Also, the entire business of a hero rescuing the beautiful maiden, I call Bull.

I get slashed by a sword and my female body gets abducted, and he wants me to thank him?!?! Can it be less of a tragedy?
