TMNS

The TMNS, sometimes shortened further to NS, is a spinoff AU based on and similar to the SKELESIS AU where Martel adopts Calibri, Tinero, and Papyrus. Like SKELESIS, the AU is heavily based on the 2012 incarnation of the Teenage Mutant Ninja Turtles. Other characters, like Oswald and Belle, join the gang for refuge and family as the lair with the ability to add new room expands.

Story
Monsters are on the surface, though their relationship with the humans are tense, as the latter is very hateful towards the former. Jerry, one of the humans, plots against the monsters. He kidnaps three skeleton monster babies from their families. However, Martel, wanting to start a new life and reform, stops him and saves the babies. He takes them in as his own and single-handedly raises them in a lair hidden away. With the tension between monsters and humans becoming worse, the skeletons stay hidden away for their entire childhood.

When they turn 15-16, the trio are allowed to go out at night. They meet human sisters Emily and Belle, who accepts the monsters, and Oswald, a fellow skeleton monster. They save Belle from Jerry and eventually saves Emily. They then meet another skeleton monster named Cooper, who is on the run, along with a human child he adopted, named Sofia. Martel allows for all of them to stay.

They meet Tommy, a blind man who runs a small restaurant. He happily accepts the monsters. Belle is a regular at his place. They meet Wyatt, a close friend of Belle's.
