Set during City of Glass.

Disclaimer

I own none of the characters except Luna Yuki, Mika Yuki, and Jasmine Fox. The rest belongs to Cassandra Clare.

Clary POV

I sighed remembering the fight I just had with Jace. He said I was fucking useless! I'm not! He doesn't understand my situation. I really want to save mom but if they don't need me, then they can save her on their own. I'll go my way with her majesty Luna. I scribbled down a thanks to everyone and apologizing that I 'mess things up'. I made a portal and teleported to the Institute, then Luke, and my home to gather all my stuff. My last portal went to her majesty Luna. I kneeled immediately.

"Clary. What have I told you? I hate it when you kneel in front of me, and I bet you started calling her majesty again." Luna said.

"I apologize your majest- I mean Luna." I said rising.

"I'm glad you're back, but what brings you here? Don't they need your help in the war that's coming?" Luna asked.

"They don't need a 'useless weak mundane'" I said.

"You didn't show them your abilities?" Luna questioned.

"No. I was nervous they might have treated me different. But maybe if I did, they wouldn't be there for me when I needed them." I said nervously.

"You're going to help them in this war. Partners? It's been forever since I had some fun." Luna asked.

"Of course." I said, and we went about our days until the war started.

Meanwhile...

Jace POV

I felt really bad for yelling at Clary, so I walked to Amatis' home to apologize. I heard a crash and someone yelling 'Clary'. I knocked on the door and soon Amatis opened it.

"Is Clary here?" I asked.

"No. She left." She said holding out a piece of paper.

Dear, well everyone,

Jace helped me realize that I don't belong here. So I'm leaving all the shadowhunting business behind. Since you most likely will never see me again, I figured I should tell you something. I am not a weak mundane. I'm a proud shadow hunter with a little bit of Mage and god blood serving under her majesty Luna. I pretended to be weak, because I was afraid of showing power and authority. I thought you all would treat me differently. I wanted to give you guys gifts, but since I can't think of anything now, I'll have it sent over when I make it. Don't even waste your time trying to track me down. I made everything that I might have left untraceable with my magic. If we are destined to meet again we will. It all depends on her majesty's wish. So for now hasta la vista everyone.

~Clary

P.S. Hasta la vista means Until we meet again

I said goodbye to Amatis and went to show Isabelle this. When I did she got really upset.

"I didn't want her to be fighting, not leave everything behind. And who the hell is this her majesty Luna person?" Isabelle whined.

"It's probably for the better." Alec said.

"Maybe." I said and went on with life thinking about Clary.

About 3 days later during the battle

"Izzy!" Alec called out. But it was too late, the demon was about to kill Isabelle. Sudden,y there was a gust of wind and a red hair girl blocked the attack with a sword.

"You okay Iz?" She asked.

"Clary!" Isabelle squealed and was about to hug her when Clary backed away.

"No hugging." She hissed.

"What's wrong Clary? We haven't seen you in 3 days and you suddenly changed." Isabelle said sadly.

"I was never any different. Besides it's not like you guys want a 'weak usexless mundane who always messes things up'." Clary said.

"I never said that! Jace did!" Isabelle protested.

"But did you stop him or deny it? I thought so." Clary said. "I'm not here to help you shadow hunters intentionally. I came here on orders to defeat Valentine and his armies."

"Clary! Don't be rude to them." A blue purplish hair girl ran up.

"Sorry Luna. But it's true." Clary said.

"I know it is, but don't take your anger out on them. Instead take it out on the demons. We came here to help the shadowhunters, not start a fight with them." The girl said.

"Hai."(Okay) Clary said.

"Wanna change and see how many we can fend off? Only one change though so choose wisely." Luna said.

"Let's see who wins." Clary nodded. They put the hilt of a dagger in their mouths and held it there for god knows why. Then there was a dim light from them as they shrank and in their places were a wolf and a jaguar. Now I understood, they needed their hands and legs which were now paws to run, so they use their mouths to hold their weapons. I saw them move at incredible speed. It was hard to believe that the Clary I knew, was now able to kill demons and morph into an animal.

"Tell me that's Clary and not my imagination." Isabelle said in awe. I nodded.

"Clary's the wolf and that Luna girl is the jaguar." I said.

"I know that part but how did she do it?" Isabelle snapped.

"Probably thanks to her extra angel blood, tiny bit of Mage and god blood too." I said like it was so obvious. I saw a demon about to attack Clary and was about to rush to protect her, but then a jaguar jumped and blocked the attack. Clary changed back and so did the jaguar.

"Clary up!" Luna said and they both jumped and wings sprouted from their backs. Luna had blue purplish one with the tips black and Clary had beautiful emerald green wings. They formed a bow in their hands that looked like it was made of ice and began firing, successfully hitting only demons. Most of the demons were gone now and Clary flew down near us and looked ready to collapse. Luna flew down quickly and held Clary up.

"Woah. How much energy did you use Clary?" Luna asked.

"Don't know. Lost count." Clary said.

"Rest here. You guys protect her." Luna said before she made a few clicks and whistles. One of her bracelet and an anklet flew off and grew larger into a silver and turquoise dragon.

"Protect Clary." She ordered them. "I'm heading back out to defeat Valentine and Sebastian."

"You can't fight them alone." Alec said.

"I don't want to waste more energy trying to protect you guys." Luna sighed. "Don't underestimate us Dark Shadows. When we get mad, all hell breaks loose."

"Clary's part of the Dark Shadows?" Isabelle asked surprised.

"Yeah." Luna said.

"Isn't the Dark Shadows a gang of only the strongest shadowhunters? What is Clary doing there?" I asked.

"You are underestimating Clary even though you seen her in action. She has much more potential, I just hadn't had much time to train her. She is already going at a fast pace. When I met her 4 years ago, she was the weakest thing ever. But then when I took her under my wing, she learned things Shadowhunters take 5 years learning in less than 5 hours." Luna said with a hint of anger in her voice. "Now excuse me, you're wasting my time."

Can Luna defeat Valentine and Sebastian?

Just how powerful is Clary?

I have no clue so you have to wait until next time!
