Attack on Titan: Betrayal And Unknown [Book 3]

Kousagi, The Guardian of The Walls and Fortress

Erwin Pov

Chibi Chibi isn't doing so well from what happened to her is nothing more what I can do. She's going to die....her life is too short and it didn't go so long for her life is needed outside the walls and for freedom. 

"Commander Erwin Smith?" I heard as I look up to see someone standing there.

"Who are you and what do you want?" I asked.

" I am Kousagi, the guardian of the walls and fortress. I was sent here to return this to my dear friend, Chibi Chibi." She said holding something shining before my eyes that flow itself into Chibi Chibi's chest as she began to feel normal and not cold.

"Kousagi..."

"Take care...be safe." She said fading away and I nodded.

I was backed up with the other's that I look over the wall to see Rod arriving here and now. Levi and Hanji informed be that my friends are down there blocking the black energy Duchess had sent out and they are not destroyed that made it more powerful than before. 

"Eren, we've got a plan on getting rid of Rod. You'll need to transform into your titan form to be to do this." Captain Levi said.

"It seems like the other's down there are struggling with those creatures that Duchess released. DAMMIT! They're breaking out and its no use into stopping them!" Hanji exclaimed.

We looked down where the village was being broken down by the force of those creatures were now entering as I gasped in shocked.

"Those creatures are not going to last long unless Duchess/Kousagi is yet still here to destroy them." Dr. Shizumi informed.

"We don't have much time!" Hanji yelled as we stood horrified at the sight of Rod's appearance before us.

"Quick! Transform now!" Levi ordered.

"Eren-chan." I heard Kousagi's voice as I gasped to see her appear in front of us wearing a short green skirt, white top with that was short sleeve, and she wore short ankle boots.

"Kousagi..." I whispered.

"Kousagi, the guardian of the walls and fortress." Hanji said.

"I came to thank you for helping the dark soul faze through me and now I can no longer be under control." She said.

"B-But what about..."

"It's okay. Not everything will be the same once i'm around and i'll stop Rod from coming any further." She reassured.

"Wait! Let me help you!" I begged to do the job for her myself.

"I'm afraid not. You see, Rod has already been at his limit where he could tolerate the main citizens inside the wall and not on the outside. Let me do the job as a token of gratitude." She said summoning a synth and grasped it.

"No, you can't-" She pointed it at me and gave us a sad smile.

"Goodbye..." She said jumping back to where Rod was fully standing as she disappeared into his body to fight the source within him.

Kousagi....
