"My portals are way cooler!" Leo shouts to his twin brother. Donnie who said his tech was way better than Leo's whatever ability.
"Auntie look! I made you a drawing!" Mikey said as Raph offered you some juice— which you happily accepted.
You were some yōkai. Fortunately, Splinter's sister..the turtles auntie! And the turtles were ecstatic about it! They had a relative!! And it just had to be a nice powerful yōkai. You were human..once— let's not talk about how you turned into some yōkai, it hit home.
You were simply in the turtles lair and your four mutant turtle nephews just wouldn't stop impressing, showing off and trying to get your attention- not that you minded. You were just talking with your brother after years of separation, you're on vacation here in New york and your teenage mutant turtle nephews forced you to stay here in their lair..in the sewers with them! The surface was boring anyway, you ended up agreeing and also meeting some of their friends. Maybe you could help them with a few missions? Who knows.
"Sorry about them auntie." The red masked turtle said as he scratched the back of his neck which your brother— Yoshi(Splinter) sighed at, he doesn't know how to make his sons behave now that they're teenagers.
