••••••••••••••••••••

Weeks turned into months as the search to repair (Y/n)'s memories became futile. Louis and the others were trying their best to help her remember, but nothing they did worked. While she couldn't figure out who she was trying to remember, she had no doubt about her past with Louis. She asked him to tell her stories of their time together before the Great Collapse, which he happily obliged. He told her all that they did together even after learning it wouldn't help her regain her memories.

It would always bring a smile to Louis' face as he reminisced in the memories. For some odd reason, his memories of (Y/n) are vivid, but everything else, including many memories of his sister, were no longer a part of him. When he woke up after being revived as a revenant, he only remembered his name and (Y/n)'s.

It took him a while to remember his own sister, Karen, but it took only mere seconds for him to remember his childhood friend. He wasn't sure why, but he wasn't complaining. It was nice to have memories of her when he woke up in such a distraught state after being slaughtered by one of his classmates, Cruz. He wondered if his strong feelings toward (Y/n) were the reason his memories of her remained intact or if he was one of the lucky revenants to keep at least a slither of his memory.

One day while Louis was out in search of a blood spring, he came across another revenant who went by the name Echo. After defeating a fellow revenant who frenzied and seeing her purify the vestige left behind, he immediately thought of (Y/n) after traveling through the memories of the revenant. He took her and her companion, Io, back to the church where everyone else was waiting.

When they arrived back at home base, Louis shared what all happened with the others. Looking toward (Y/n), he saw a familiar gleam of hope in her eyes. She stepped forward, meeting his crimson gaze with her (e/c) one. "Is there a possibility I could regain my memory?"

"There is, but we would have to find a vestige belonging to you," Louis explains.

The girl's hope dwindled, her once gleaming eyes becoming dull. "I see..."

Seeing the smile on her face vanish, Louis placed a hand on her shoulder. "We will find one and return your memories."

(Y/n) wanted to believe him, but she couldn't knowing how minuscule the chances of finding a vestige belonging to her was. "The chances of discovering a vestige belonging to me is slim to none. Maybe my request is too much..."

"Don't give up just yet," he retorts. "For now, we need to search for blood springs. Will you accompany us, (Y/n)?"

"It will do me good to get out. It's been a while and a change of scenery would clear my head. Let me grab my weapon and we'll depart." She shuffles over to Murasama, who'd been modifying her bayonet rifle. She thanked the small girl after retrieving her Black Bayonet and regrouped with Louis, Yakumo, and Echo at the entrance of the church. They departed from home base with their purifier masks and headed to the ruined city center in hopes to discover blood springs and their potential source.

On the way, (Y/n) asked Echo a few questions in an attempt to get to know her. The golden-eyed girl answered all her questions, which livened their trek through the ruins as they fought the Lost that tried to sneak up on them from behind piles of debris.

Reaching the parking garage, the group was attacked by a stone-crusher. Louis, Yakumo, and Echo dashed forward with their weapons raised. (Y/n) kept her distance, firing her bayonet and using gifts to assist the others. The large enemy swung its hammer around in a sweeping motion, forcing everyone to dodge.

(Y/n) saw the stone-crusher stagger after its attack and charged forward. The blade attached at the tip of her rifle glinted in the sun as she closed the distance between her and the Lost. With all her strength, she plunged the sharp blade into its chest and pulled the trigger. A gunshot echoed throughout the parking garage as the stone-crusher cried out before its body turned to ash, its heart being obliterated from the girl's attack.

Lowering her weapon, (Y/n) shook the blood off the bayonet. She turned toward the others, smiling innocently. "Shall we continue forward?"

Yakumo smacked Louis on the back with a smirk. "She's a keeper."

Underneath his mask, the corners of Louis' mouth quirked upward in a faint smile. He gazed at (Y/n), who returned to chatting with Echo. "She survived for months by herself. Bringing her along has already proven to be beneficial."

"That's your response?" Yakumo sighs, shaking his head. "How boring..."

"What do you mean?" Louis inquired, eyebrows furrowed slightly.

"You reunite with your childhood friend after all this time and that's what you have to say?" The redhead scoffed. "I feel kinda bad for (Y/n) now. All that staring you do..."

"Am I still-?" Louis went to ask but was interrupted by an excited (Y/n).

"Louis, we found one!" The girl announced excitedly.

Louis and Yakumo rendezvoused with their female companions. They could hear voices emitting from the vestige, which was hidden in a box not too far from where they fought the stone-crusher. (Y/n) stared down at the pulsating fragment of her memory, listening to the voices. She recognized hers and Louis', but there was another man's voice she couldn't identify.

Echo glanced at the vestige before looking up at (Y/n). When she received permission from the (e/c)-eyed girl, she picked it up and purified it. (Y/n) placed her hand on Echo's arm to join her on her adventure through her memories.

At the last second, Louis held (Y/n)'s hand and tagged along for the ride. He felt the same tug on his body when Echo purged the vestige they discovered after defeating the newly turned Lost earlier that day. Eventually, the three were pulled into the memories of (Y/n).

Looking around, (Y/n) admired the beautiful scenery of the trees around them. She wasn't sure where they were, but her head snapped in the direction of a pond when she heard two voices. It was her and Louis. Listening to their conversation, she realized it was the day after she and Louis learned they were accepted into the university. They were both happy to know their paths still aligned and they wouldn't have to say farewell to each other just yet.

The next memory was a short summary of her days in the university before the Great Collapse. She was alone, inside the library studying. Even though she was trying to read the book in front of her, all she could think about was Louis. She hadn't seen him in weeks and couldn't hide her sorrow.

Moving on to the third memory, it was after the Great Collapse. (Y/n) miraculously survived the frenzy of the Queen, still being human. She was hiding from the Lost that roamed the streets. Her search for a shelter was interrupted when a group of revenants stumbled upon her hiding in one of the buildings. Unable to fight against them, she was taken back to their safe house and used as a source of blood.

The final memory was the worst. (Y/n) could feel her heart racing as she relived the memory of her death. A couple weeks after she was captured, one of the revenants became greedy and visited the room they imprisoned her in. He overpowered her, pinned her to the ground, and sunk his fangs into her neck. She struggled against him, trying to kick him and scratch at his face. Crying out in pain, she could feel her body growing weaker as the revenant drained the blood from her body. Her heartbeat was decreasing as her skin was losing its color. Unable to lift a muscle, her arms fell limply to her sides. She felt her entire body shutting down, her eyes slowly closing as she accepted her fate.

When (Y/n), Echo, and Louis emerged from the memories, they were all silent. Yakumo, being the only one who hadn't seen the memories, glanced around at his companions. Seeing the petrified expression on their faces, he decided to remain silent.

Unconsciously, (Y/n) reaches up to touch the side of her neck. Her fingers traced over the scar left behind from the revenant's fang. She tried to think of something to say, but only a tear cascaded down her cheek as the fog in her mind was lifted. While her memories were restored, the only question that crossed her mind was-how did she become a revenant?

After a suffocating silence, (Y/n) managed to form a single word. "Well..." She looked away from the others, clearing the lump that was lodged in her throat. "At least my memories are back..."

Yakumo wanted to ask out of curiosity, but he knew now wasn't the time by their grave expressions. "We've got one thing checked off our list. Let's find those blood springs and their source."

(Y/n) nodded in agreement. "Yes. We also shouldn't linger around for too long. Who knows when more Lost will show up." Yakumo and Echo slung their weapons over their shoulders, walking back the way they came to search for an alternate route. The (h/c)-haired girl grasped her bayonet rifle tightly, lookin out in the distance before deciding to follow the others. When she noticed Louis wasn't tagging along, she turned toward him with a puzzled expression. "Louis, are you all right?"

Louis lifted his head, gripping his sword tightly. His back was facing (Y/n) and she was unable to read his expression. When he felt a hand on his arm, he looked over at her. Emotions in turmoil, he stabbed the tip of his blade into the asphalt below and promptly wrapped his arms around her smaller frame. He pressed his cheek into her hair, inhaling her scent. It calmed him and cleared his mind, allowing him to finally express his feelings after viewing her memories. "I'm sorry, (Y/n). I should've been there. If had been, you could've kept your humanity. Seeing and hearing you in such pain... I should've searched harder for you."

The tenseness in (Y/n)'s shoulder vanished. Her hands crept up his back once dropping her bayonet rifle, coming to a stop just below his shoulder blades. "You don't need to apologize. I'm glad I was able to have my memories returned to me even if some of them aren't very pleasant. Now I know for certain you were the one I was trying to desperately remember. I feel...whole. It's a strange feeling, but a good one. Regardless of the circumstances behind my death, we've been reunited. Even though the world around us is crumbling, I couldn't have asked for a better miracle. We're together again. That's all that matters."

"Yeah," Louis said, smiling underneath his mask. "You're right. I'll make sure to protect you this time. It's a promise."
