Summary
A challenge given by my friend and fellow fanfiction writer Flightsoffiction: I loved dropping in, but what if it happened a different way? Lets have Doctor Garaki, being excited to test his new Nomu 'Kurogiri's' new quirk forgets that new quirks tend to act as if the person is four and learning to use their quirk for the first time! And it just so happens to drag our reluctant heroes into BNHA to different locations. The big difference? Splinter is going to the Battle Nexus, but decides to bring his sons, leery of lying to them about the whole thing after the Ninja Tribunal erased their memories. On their return trip, they are all deposited into different parts of Japan just like dropping in. Our first person to drop in? Splinter. His location: I-Island. Hope you like Flightsoffiction!

Summary
Magic once ruled the world, and Wendie is one of the last witches still seeking out hidden magical beings and people who fall through the cracks. While investigating rumours of dragons, a rat yokai, four kappa, and even a demon who tried to take over New York, she discovers the TMNT—four boys with powerful mystical abilities. Believing their magic accidentally transformed them and their 'Master' into animals, and mistaking Splinter’s title for abuse, Wendie enacts an ancient spell to “save” the turtles, reverting Splinter to human form and taking the boys to raise as her own. But magic—and the bonds of found family—aren’t so easily undone.
