Is It Wrong to Pick Up a Yandere in a Dungeon?

(I still don't own Danmachi.)

The day started much like any other for Aiz. She woke up before the sun rose and started sword training. She would do 100 cuts from above the head to directly in front of her, 100 slices left to right and 100 right to left but, when she was about half way through she thought of a certain white haired boy. This had started happening more lately but, she didn't mind. In fact, she quite enjoyed thinking about him. He was just so cute, he looked just like a bunny and his hair was just as soft as a bunny's. Aiz's features started to soften as, she remembered all the lap pillows and all the the times she got to hold him. Sure, the only times she ever got a chance to hold him was when she was rescuing him, after he inevitably pushed himself too hard and got hurt again but, that kind of made it better in a way. She loved being able to take care of him and protect him but, as she followed that train of thought her cute smile started to contort into a scowl.

The swings of her sword got increasingly intense with every swing and her grip on the sword was so strong she was almost crushing the hilt. She had began to think about who usually gets to take care of those things.There was that stupid little prum that was always clinging to him, his goddess that was always disrespecting her by getting her name wrong, that whore prostituite renart he brought back from the red light district and that girl from the far east who ran to his side in the war game against Apollo when Loki Familia refused to let her help. Aiz pondered all this and she started feeling emotions she didn't understand. Was it anger? Fear? jealousy? She wasnt sure.

Aiz's thoughts continued, "Why does he need all those girls anyways? What could they do for him, that she couldn't? Nothing, it isn't fair! They join some useless Goddess and get a monopoly on Bell." The black flame inside her was raging with the fury of a thousand suns. She usually would just imagine monsters when she was doing her practice swings but, now she was imagining cutting off those "stupid little whores" heads. They took all Bell's attention and that was when she decided something needed to be done about it. She wasn't really sure about what she should do but, she decided she would atleast have to go find Bell and talk with him about it. This current arrangement just wasn't acceptable.

She wasn't sure what she was going to say but, nonetheless her feet started heading to the dungeon. Bell had a very predictable schedule that she knew from their time training on the wall together. He went to the dungeon almost every other day without fail. He often would go more often then that but, only every other day was a guarantee and luckily for Aiz today was one of the days he was sure to come no matter what. When Aiz arrived she realized that she was way too early to meet Bell so, she sat on the fountain in the area outside the entrance of the dungeon. She sat and thought about what she wanted to say. Would she offer to train him again? She would get to spend more time with him that way but, that didn't really deal with all those other girls? Would she invite him to join her familia? No, she didn't have the authority to that. It was while she was in the middle of these thoughts, she heard a voice.

"Hi, Aiz!" She heard someone cheerily greet pulling Aiz out of her thoughts.

When she refocused she saw Bell and that "stupid little prum girl" as Aiz thought of her.

"Hi Bell!" She returned his greeting with a big smile. "You going to the dungeon today? You look a little short handed. Where is the rest of your party?"

She asked curiously trying to ease into what she really wanted to talk about.

"Yes, but Welf is busy at the forge. Mikoto is helping out Lord Take and Harihume is busy with her maid duties"

"I see, so you decided to go on a dungeon date with your little prum?!?" Aiz said with contempt.

Bell started waving his hands back and forth "It is nothing like that!" But, Lili decided this was a good chance to send a message that Bell would be hers so, she grabbed Bell's arm and pushed herself up against him. This was a bad idea. Aiz became enraged and gave Lili a look that could kill so, Lili decided to let go.

"Since you are short on members, how about I go with you today?" Aiz asked Bell but never took her glare off Lili.

"Lili thinks that's not such a..." Lili trailed off as Aiz intensified her gaze even more and the aura of the level six was simply overwhelming for the little level 2 prum.

"What do you say Bell?" She says as she finally stopped glaring at Lili and looked Bell in the eyes with a cute smile.

"Yeah, that would be great!" Bell excitedly agreed seemingly not noticing the hostility between the girls.

He was just excited to go on a dungeon trip with his idol. Aiz then got to her feet and grabbed his hand heading towards the dungeon. Bell's face flushed red in a way Aiz thought was extremely cute. This made Lily jealous so, she again began clinging to his other arm, which wasn't missed by the blonde knight who started clinching her hands into fist and clinching her teeth.

"Ow!" Bell squealed out in pain as, his poor hand was smashed under the pressure of the level 6's grip so, he reflexively pulled his hand away. "Stupid Prum!" Aiz mumbled under her breath blaming Lili for Bell pulling away.

When they finally made it into the dungeon things went by rather easily with a level 4 Bell and a level 6 Aiz the lower and middle floors were a piece of cake and they easily made it to the Under Resort in just a few hours. They all decided they might as well pay a visit to the city of Rivira. They were checking out stores but, predictably everything was way overpriced but, it was still fun to look and everything was going fine as, they walked into a weapons store until the Prum girl got a little too close to Bell for Aiz's comfort.

"Hey Lily you think I could speak to you outside?" Aiz asked through gritted teeth.

"Um sure..." Lili agreed a little too afraid not to.

Bell was too busy looking at the knife selection to even notice they had slipped away.

Aiz grabbed the Prum and brought her to an isolated alley to speak in private.

"You need to leave my Bell alone!" Aiz spit out

"He is not YOUR Bell." Aiz fist clinched again "He isn't even in your familia! You couldn't have him even if you wanted to!" Aiz's teeth clinched so hard her head was shaking. "And even if Loki allowed it, Hestia says she would never allow you to date him." Aiz hand slowly reached towards Desperate as, the black flame started to roar. "Honestly, you should just leave him alone, all you are doing is leading him on. You just going to hurt hi..."

Swish! Off goes Lili's head.

"SHUT UP! SHUT UP! SHUT UP! SHUT UP!" Aiz screams as she keeps hacking at the obviously dead body. Blood is flying everywhere and the little Prum is barely recognizable at this point as, Aiz's cut her into bits. That is when Aiz sees people starting to head her way and decides to call Tempest to make her escape. She heads to the secret hot spring spot to clean herself up as, she is covered in blood and it would be quite obvious who did this if someone was to see her. Luckily( for Aiz) with her level 6 speed boosted by Tempest, nobody would be able to recognize her as, most adventurers down here are only level 3 or lower so, she would just appear as a blur.

Meanwhile with Bell, he notices both his companions are gone and decides to go look for them when, he sees the commotion. Bell slowly works his way to the front to check out what happened. That is when Bell sees it, a body that has been utterly obliterated. It was the most overkill he had ever seen. He almost puked just looking at it. Although, at first he didn't know it was Lili because the head had already been recovered by Bors and the "authorities" of the town. That was when Bell saw Bors. He was about to ask him what happened when Bors held up the decapitated head above him and turned to the crowd.

"This may be tough but, does anyone recognize her?"

"It's Lili" Bell screams through his tears barely able to get out the words but forcing them.

"Calm down, you know her?" Bors asked

"Oh God! Oh God! Oh God!" Was all Bell could say about to hyperventilate.

"We can't help you kid unless you calm down and talk to us."

"Sh-sh-she is a member of my familia. Sh-sh-she was my supporter" Bell says doing his best to talk between sobs

"Do you know anybody who would have something against her?" Bors asked.

Before Bell could answer a certain blonde haired knight had made her way back from her impromptu bath and cleaning session. She had made it quick to not make it obvious and dried herself quickly using Tempest so despite just cutting someone into bits, she looked perfectly normal.

"M-Maybe Soma familia. Th-that was her last familia." Bell told Bors still sobbing as Aiz pulled Bell into a hug and started petting his head to comfort him. Aiz would never admit it for obvious reasons but, she was actually quite happy with how everything was working out. She got rid of that stupid Prum and now she was getting to hold Bell and take care of him. She was a little bit mad that he was making such a big deal over "that useless prum" dying but, as long as she had Bell to herself it was okay. Bell on the other hand was almost inconsolable but, being held against Aiz's chest was certainly nice nonetheless so, he didn't pull away.

"It's okay Bell. I will find who did this and make them pay." Aiz quietly whispered into Bells ear in an attempt to comfort him.

Bors was about to speak up to ask Bell another question but Aiz gave him a look that could kill and he thought better of ruining this moment and instead just gathered the remains and got them ready for transportation to the surface. After a long while, Aiz and Bell finally separated their embrace after Bell had cried all the tears his eyes would let him and despite his grief he was able to compose himself again.

They spent the rest of the day interviewing potential witnesses and potential leads but eventually found nothing to lead them to the killer much to Aiz's happiness and Bell's despair. It was then decided that they should head back up to the surface because, they had already been down there far longer then expected and people would start worrying if they didn't get back soon so, Bell wore Lili's bag back to the surface while Aiz carried what was left of the body in a body bag back to the surface. Bell had a couple moments where grief almost overwhelmed him on the way up but, Aiz was always ready to hold him and protect him. When they had to finally part on the surface back to their respective familia Aiz, was rather upset as, she thought about what was waiting for him there but, she had gotten closer to Bell today and took out a rival so, she decided to leave well enough alone and go home without issue.
