   Summary

   Leo is fine. Despite what his brother’s might tell you, he’s doing great. Sure, he hasn’t quite been himself since Splinter’s death, but he’s adjusting and his brother’s silly little intervention wasn’t going to change that. He tried to tell them as much before the dart pierced his skin and everything went black.

   He now finds himself half-way across the world in Japan at the mercy of his unknown assailants. Just as he’s about to give up all hope, he’s saved by a band of Yokai Samurai led by a rather nice white rabbit. He’s not sure how he’ll ever get home, but he trusts Yuichi Usagi to get him there.
