I had so much fun writing this chapter. Finally got it done. Here's the third chapter. Enjoy.

Previously

"One Titan got past. He's headed for Eren." Connie yelled as he pointed to the Titan that was approaching Eren's Titan body. The nearby soldiers stared at Titan, wishing that they could get there in time to kill it.

"Eren." Mikasa yelled as she propelled herself towards Eren. She knew she wouldn't make it. She knew that if the Titan got to Eren, the mission would fail once again. The Titan was in reach of Eren's leg and as Mikasa and a couple other soldiers were flying towards Eren, an unnoticed figure was racing towards the same target.

"Hurry. We must protect Eren." The mission leader yelled. The soldiers were running towards Eren, avoiding the oncoming attacks of other Titans.

"They're going to come into contact." A fellow soldier said. The small group of soldiers watched in fear and horror as the Titan swung its fist back ready to punch Eren.

"Eren!" Mikasa screamed. She knew. They all knew that they wouldn't get there in time. They were just too far away. And then it happened.

A figure, cloaked in black, shot her rappelling cord at the Titan's body and cut the nape of the Titan, letting his body drop to the ground. Flipping in the air, the figure landed on the roof beside Eren.

"Who is that?" Reiner asked as he stood on the roof with Armin and Jean next to him as the two were fighting a Titan.

"That's the figure we saw with Instructor Shadis that day." Jean stated, his eyes grew wide as he watched the figure cut the nape of another Titan before moving on.

"But who is it? They don't bear the crests of the military divisions." Armin said as he stared at the silver crest on the cloaked figure.

"I don't know Armin, but whoever they are, they're on our side. With them, we can retake Trost." Reiner replied as he killed the Titan in front of him.

Everyone saw the figure move, the way she used her 3D Maneuver Gear, the way her face was never seen. Her strikes were fast and clean, killing the Titans in an instant. They were all relieved, knowing that with the unknown figure on their side, humanity would have a chance to win. As Eren got closer to the gate, four Titans quickly walked through and were walking quickly towards him. Just as the other soldiers were about to abandon their posts to kill them, the figure yelled out.

"I will protect your Titan shifter until he gets to the gate. Finish off the other Titans." The figure yelled as they ran on the roofs of houses beside Eren's Titan body. The mission leader heard the order clearly and yelled back.

"Very well. We are counting on you." The figure nodded back to the mission leader before using her rappelling cord to pull themselves to the four Titans. Within seconds, two of the Titans were on the ground, their napes cut out. The figure quickly shifted and locked her rappelling cord onto the closet Titan before shooting towards it, cutting its nape out, before changing direction to the last Titan.

"How are they moving so fast? They cut down those Titans in mere seconds." Connie asked Jean, who stood next to him.

"I have no idea. Come on, Titan on the right." Jean and Connie jumped off the roof and attacked the Titan. The battle raged on for minutes. Titans and soldiers falling everywhere. Eren had finally made it to the gate. As he walked towards it, the figure jumped onto the closest roof and stood, watching.

"Go Eren!" Armin yelled as Eren roared, slamming the large boulder into the breached gate, closing it off. There was a moment of silence. Eyes were widening, jaws dropping, tears falling.

"You all didn't die in vain." Rico had dropped to her knees and stared at the back of Eren's Titan body. Reaching down, she picked out the green color flare, loaded it and fired it into the air, signaling the victory of humanity.

"For the first time in history, humanity has won against the Titans."

Far away, on Wall Rose, a soldier stared out at the district of Trost, at the color of the flare.

"Sir, it's a green flare. The mission was a success." Commander Pixis grinned as the soldiers behind him began to cheer.

"Send in reinforcements. Bring in the elite soldiers." At his command, the soldiers around him got to work, some dropping down into the city and others spreading the message.

Meanwhile, Eren's Titan body hadn't moved since he collapsed against the sealed gate. Armin flew over to Eren and landed on his shoulders. Rico and Mikasa following him.

"We have to get him out of there, but how?" Rico asked. The three were thinking when a voice sounded behind them.

"Cut him out." The three spun around to see the cloaked figure whom had helped them out.

"Are you insane?" Mikasa yelled and was about to argue with the figure when a hand gripped her shoulder. Turning around, Mikasa saw the grim face of Armin.

"We have no choice. He isn't coming out by himself. If he lies in the nape of the Titan, we just have to cut the nape out." Armin said, trying to diffuse the brewing tension among the two.

"I'll leave you two to it. Hurry and bring him back." Rico said as she got off of Eren's Titan body and headed to regroup with her Garrison comrades. The two had also noticed that the cloaked figure had also left them alone, probably during Armin's speech.

"I'll do it." Armin cut the nape out and found Eren stuck in the Titan. Pulling and tugging did no good. So Mikasa had no choice but to cut the Titan flesh holding Eren. As she did, Armin was still pulling and hadn't noticed Mikasa was cutting it until it was too late. He and Eren went tumbling down the back of the Titan's body and fell on it's legs.

"He's burning up." Mikasa dropped down to where her childhood friends had fallen and felt Eren's forehead.

Thud.

A large shadow covered the three teens on the floor.

Thud.

Mikasa and Armin turned around to see two Titans coming for them.

"Mikasa, what do we do?" Armin panicked. They were cornered. No buildings were around for them to use and a Titan's body was blocking them.

"Tch. God damn brats." A rappelling cord struck in the wall next to the nape of the Titan. In mere seconds, the two Titans had their napes cut. It was then that Eren's eyes decided to open. As they did, Eren, Mikasa and Armin saw the two Titan bodies fall to the ground.

"Mikasa?" Eren spoke. Mikasa and Armin turned to face their friend who had just woken up and where about to ask if he was okay when they saw Eren's eyes widen. Turning to what he was looking at, their actions mirrored Eren's. Standing on the dead body of one of the Titans, was the cloaked figure. Eren could see the symbol on the back of the cloak. A silver crescent moon.

As the figure turned around, she flicked her swords, getting the blood off of them.

"Nice abilities you got there, shifter." The figure spoke to Eren.

"Who are you?" Mikasa yelled to the figure.

"A comrade. Who else?" The figure retorted, feeling the anger from Mikasa rising.

"What military division are you with?" Armin asked, worried for the figure's safety from Mikasa.

"I don't know. Why don't you figure out? See ya." The figure jumped up and began to run towards the houses before switching to 3D Maneuver Gear and flew out of their sight.

Once the figure had left, Eren had fallen unconscious once again. Seeing that the surrounding Titans had been killed, they noticed a bunch of soldiers bearing the Wings of Freedom rescuing the elite squad. Eren had been taken from Mikasa and Armin and escorted down to the prison cellar, where he would stay until his court trial date.

Meanwhile, the two Survey Corps members met up with Commander Pixis at the top of Wall Rose.

"Pixis, what happened here?" Erwin asked. Pixis explained the mission and the discovery of the Titan shifting abilities in Eren Jaeger.

"Who was that black cloaked brat?" The voice of the man standing next to Erwin asked.

"They never said their name. Here is what they gave me." Erwin took the paper Pixis was holding out and read it.

"One of the top ten from the 102nd Training Corps. The Training Corps that produced some elite soldiers I know? That one?" Erwin asked.

"Yes. The soldiers in the mission will have more information on her. You should talk to them." Pixis replied.

"Levi." Said man turned away from the view of the battlefield to face his Commander.

"Gather the elites from the 102nd Training Corps and have them brought to Headquarters." Erwin said.

"What about the black cloaked brat?" Levi asked.

"Find them."

I hope you all liked it. R&R:)
