I don't own Soul Eater or Star Wars Rebels just the idea to combine the two of them and the plot/storyline

Third P.O.V:

"Look Sabine, I know you have your thing going on and I have mine but we need to find a way to get in more training and hunting missions if I'm going to become a death scythe," Ezra stated.

"I know Ezra and I'm trying but with me being part of the rebellion and all it's not that easy to sneak away to train or do missions," Sabine explained "maybe if you stayed in weapon form I could sneak you onto the Ghost and you can just stay hidden in my room and turn into a weapon when you need to hide.  It should be able to keep Kanan off your trail."

"No, no, no, bad idea Sabine, bad idea.  Even if me being in weapon form could keep a Jedi from sensing me do you really think I'm going to stay in weapon form for that long, weapon form really puts a crick in my back," Ezra complained.

"I know but do you have a better idea?" she questioned.  Ezra sighed.

"No" he admitted "but are you sure that's the only way because you'd have to be really secretive because even though I'm a weapon I am still a human being with the same needs as you guys, such as food."

"I know, I know. Just give me a second to think."

"Okay."

"Hmmmmmm," Sabine hummed to herself in thought.  She abruptly snapped her fingers as an idea came to mind.

"You got an idea?" Ezra questioned rhetorically.

"What if you joined us?" Sabine suggested.  Ezra blinked at her.

"What?"

"If you joined the rebels?  You'd become part of our crew and we can just say that as the two youngest members we want to hang out and when we go to hang out we train and maybe go on the occasional hunt for kishin souls!"

"Umm, ok.  Let's say I agree to this plan how am I supposed to become part of the rebels?"

"Tomorrow we're doing a cargo pickup here on Lothal, you can intercept it as the loth-rat and steal the cargo.  This'll get you noticed.  Then we just have to show that you're good for the cause."

"This plan is crazy."

"So is that a yes?"

"You know it is."

"Wizard!  How about we practice for a little longer maybe this time we'll get soul resonance."

"Okay."  With that said Ezra turned into his weapon form.  Sabine grabbed the hilt and ignited the sword.

"Let's go soul resonance! AAAAAAHHHHHHHHHHHHHHH!" they both screamed.  The green blade began to grow and widen, it turned pitch black.

"Darksaber!" Sabine cried and swung her trusty partner at a nearby boulder.
