Summary
Cobra has thought that he was supposed to have died for years at this point. His wife came back and saved him from Li; he felt like he should have died to save Smokey, and the very first time he thought he should have died. He was sure Sannoh and SWORD would still be the same, if not better, without him. And that feeling has been growing stronger and stronger ever since the threats have been growing larger. And now that Hyuga knows the secret that happened to another version of him in a timeline that is in his head, what can the Lovers of SWORD do for him to show him that he is the reason SWORD is what it is?

Summary
The multiverse is a large and weird place. A place where Rangers and Riders can live very different lives. Like Fossil Revice or harem Shinkenger...but who watches to make sure these worlds are not in over their heads? Kamen Rider and Super Sentai are owned by Toei Company, Ltd. Power Rangers are owned by Hasbro. I own nothing but the idea and any OC I create in this series.

One day soon, he might have to do the one thing he never wanted to do: kill a man.

Summary
This is a series of one-shot stories featuring my celebrity crushes. Chloe Bennet, Ichimichi Mao, Hayden Panettiere, AJ Lee, and Yano Yuuka. If you have a female celebrity that you want to see paired with any of these five leave a comment. Or if you have a female celebrity that you think deserves to be her own Mistress then leave a comment about that too. I hope you enjoy.
