Long Ago In a distant land.

A soul had found himself isekai'd into a new world as The Shogun of Sorrow already ruling Japan and enslaved it's citizens to mine it's resources.

Until a foolish samurai warrior welding a magic sword had stepped forth to oppose him but before the final blow was struck.

The soul had tore open a portal through time and flung himself into the future 

Only to find himself in a very different world than the one he left behind.

[Let's fast forward a bit here to a 1000s of years later]

Another soul had made their way into the body of Oroku Saki better known as The Shredder and with his ever loyal foot clan by his side 
What is a man to do with all the power of The Shredder? Deal with the Turtles who are just teenagers Bah! that be a waste of resources 

No he'd rather claim some woman here in Japan and get more power to further his goal of just gaining a harem of bottom heavy women (Mostly)

Either Way, These 2 forces of Evil will shake this world's Japan to the core.
