A new type of mutagen has been created.

It's powerful. It's incredible. It makes you stronger, faster, better, smarter. It gives you powers beyond even mystic understanding.

And it's not for humans.

When Y/N is painfully dosed in it. She has to find a way to get rid of it before she rots from the inside out.

And she has to do it fast because the foot has her brother.

((This may include angst and a bit more serious topics and less humor than the rise turtles usually have. But I will still try my best to portray their personalities as accurately as possible.))
