Ranma 1/2, High School DxD, Darkstalkers and the rest are owned by their respective owners. I own nothing.

If only I did.

Chapter 8

Nabiki sighed as she gave Asia an exasperated look. "Well, good news, from what I can tell, this isn't harmful."

Asia nodded. She, Nabiki, Rassie and Serafall were in the living room while Lillie and Leonardo watched what was going on from the couch. "That's good, but..." She moved her right arm to emphasize what the problem was. "I don't mind it, it looks cool, but I want to turn it off."

"Oh! That's simple!" Serafall said with a smile. "You just need to twinkle and sparkle and make it disappear." Both Asia and Nabiki gave her a look that showed they were completely lost and Serafall giggled. "If it's like a magical device..." She held up her right index finger, which glowed and sparkled. She motioned for Asia to hold out her right arm and touched the girl's middle finger before running along the back of Asia's finger, across her hand and up to her shoulder. "Okay, do you feel that?"

"Oh!" Asia's eyes widened. "I see, I wasn't looking the right way." She smiled at the twin tailed Devil King. "Thank you, Lady Leviathan." Serafall smiled and nodded while Asia closed her eyes and a soft, blue glow covered her arm, when it was over, all that remained was a black band around Asia's wrist with a gold symbol that looked like a Dragon's head on it.

"Well, that's solved at least." Nabiki nodded and looked at the data that was coming up. "So, there's no name for this, at least not yet." She gave Asia a small smirk, "so go ahead and name it whatever you want." She looked at the data a bit more closely. "As for what it does..." She frowned in confusion. "...Odd..."

"What's odd?" Serafall asked as she looked at the data. "What's this, potential power alignment thing?"

Suddenly the screen flashed and new information came across the screen. "Potential Power Alignment refers to the potential that lies within the item that was given to Asia Argento by Crom Cruach. Much like a Sacred Gear, this device will grow with the user. Should the user decide to be supportive while using it, it will grow that way, if the user wishes to become aggressive and attack, it will grow and reflect that, should the user wish to be more defensive instead of aggressive or supportive, it will grow to reflect that."

"Interesting..." Nabiki mused and tilted her head. "So what is it?"

"It is the crystallization of a portion of Crom Cruach's power linked to Asia Argento."

Asia looked at her wrist and a thought crossed her mind. "This is..." She bowed to Nabiki. "Thank you, I'll work on making sure that I can use this effectively in the future."

There was a knock on the door and Leonardo went to the door and opened it up, revealing Akeno and Yukiko, who both sighed in relief as they saw Asia standing in the living room safe and sound.

"Asia, I got a message from Nabiki that something happened." Akeno asked and Asia nodded, walking over to them.

"Yes, but I'm okay." She smiled at them. "I'm sorry for worrying you."

Akeno smiled and hugged Asia as she got close. "Of course I worry about you. If something happened, we'd all be hurt."

Yukiko bowed to Nabiki and Serafall. "Thank you for looking after her."

Serafall smiled while Nabiki nodded. "Don't worry about it," Serafall winked at the trio, "and Asia, remember, you need to treat that like a magical device." She gave Asia a stern look, "or I'll be so upset if you mistreat it." A dark aura filled the room that had Nabiki and Leonardo sweating. Lillie just looked confused.

Asia, Akeno and Yukiko all gulped as their faces turned blue. "Ah, yes, Lady Leviathan, I won't let anything happen to it."

The aura disappeared as Serafall smiled happily and clapped her hands. "Yay! Okay, you three have fun and don't get lost out there."

"Who'd get lost in their own hometown?" Yukiko asked in confusion as she, Akeno and Asia left the house.

Meanwhile...

"WHERE ON EARTH AM I NOW?!"

"Sir, this is a library, please be quiet."

"Sorry."

After they left, Nabiki sighed and shut down her Sacred Gear. "I already know how to master my Sacred Gear." She chuckled as she flopped back onto the couch. "The brain chip that was put in me to control it, I'd have to have it removed and not get overwhelmed by the Balance Break."

"Can you do that?" Serafall asked her as she walked over to sit down next to her. "I mean, I don't have that and sometimes I feel like I have to go bam! Whoosh! and Pow!" She emphasized each word by punching the air. "Get what I mean?"

Nabiki gave Serafall a weird look. "...Have you ever been tested for ADHD?"

"No, what's that?"

Nabiki shook her head. "Don't worry about it, it probably doesn't apply to Devils." Though, if it did, Serafall would be the poster child of such a problem.

Serafall gave her a confused look. "I'm curious, what is that?"

"Well," Nabiki shifted so she was sitting up more fully, "ADHD people tend to hyper-focus on stuff that they find interesting and constantly need their brain stimulated, get bored super easily, are really lazy when it comes to stuff that needs to be done but it doesn't need to be done right away or isn't new or a challenge. They also get distracted really easily."

"Easily distracted, lazy, in need of stimulation and can hyper-focus on things?" Serafall sweat-dropped heavily. "That sounds like a pain in the butt."

"Like you wouldn't believe." Nabiki shook her head. "Anyway, I doubt you have it, or if you did, it's pretty mild."

Serafall smiled at her. "Well, I never heard of it before, so maybe I do. Or I'm just crazy."

"All Devils are crazy." Nabiki muttered in annoyance. "Issei decides to put part of Albion into his soul, despite it nearly killing him, Ranma wants to fight Vasco for fun, Rias's brother seems to have the hots for her..." She trailed off and smiled nervously at Serafall, "you have the hots for your sister."

"It's more than finding So-tan cute and adorable and I want to just have lovey-dovey sexy time with her and..." Serafall hugged herself and squealed in delight. "But I'm also super worried about her." Serafall pouted cutely. "She's the heir to the Sitri family, do you know how many people would love to marry her solely for the purpose of improving their social status?" A pensive look came to Serafall's face as she thought about it. "Even though she has me as a sister and her own reputation to blow off suitors, I worry someday someone will find a way to seduce her and won't truly care about her." Her eyes teared up. "That's why I want her to be with me, then I know she'll be taken care of, but instead, she might become vulnerable since she doesn't have a lot of experience with anyone."

"Did you before you hooked up with Ranma?" Nabiki asked her and Serafall smiled and blushed softly.

"Well, I did try to date Sirzechs-chan, but Grayfia already staked her claim on him when I asked him out." She giggled and rubbed the back of her head. "I tried to offer a threesome and Grayfia would only agree if she could go full BDSM queen on me, so I had to turn that down. Um..." She blinked and tapped her chin while looking up. "...I can't say that I have a lot of experience otherwise, being a Devil King makes it hard to get time to have a date."

Nabiki stared at the Devil King in shock. "...Wait, are you saying your first real relationship is with Ranma? ...Were you a virgin before he got you?"

"Well, I didn't really do a lot of romantic pursuits." Serafall told her. "As for a virgin, I lost that a long time ago, but it's been a few centuries since I last had sex, so I was basically a virgin." A determined look came to her face. "Besides, with Gabriel as my rival, I cannot let myself get too bogged down in case she shows up and wants to fight!"

Nabiki sweat-dropped as she heard that. "I don't think she wants to fight you though." Really, Nabiki didn't think that Gabriel thought of Serafall as a rival to begin with. "If anything, she might want to be friends."

"HA!" Serafall laughed as she leaned back against the couch. "I don't see her as an enemy anymore, but friends? I don't think that would happen."

Nabiki just shrugged. "You can be rivals and friends, you know?" Serafall looked at her with a raised eyebrow. "Xenovia and Yohko quickly became rivals and friends. Xenovia used to be with the church and hunted down the supernatural and Yohko was a Devil Hunter. They both like to fight and use swords. Last I checked, Xenovia won the last three sparring matches they had. But they smile after they're done and help each other after each match." Nabiki smirked as a thought popped into her head. "I really should call Yohko and have her come here this weekend, I'm sure that Xenovia would love another sparring match."

Suddenly the door creaked and Nabiki and Serafall looked over at the door. "Didn't they close that when they left?" Nabiki asked as she got up and went over to the door to close it and blinked in surprise as she saw someone behind the door. "Ah, Sona?"

Sona's eyes widened as Nabiki was shoved out of the way and Serafall grabbed her and pulled her into a hug. "ACK!"

"So-tan! So-tan! So-tan!" Serafall giggled as she jumped up and down while hugging Sona to her chest, which Nabiki found comical as Sona was taller than Serafall.

"Um, Lady Leviathan, if you keep bouncing like that, your sister's glasses are going to go flying and break... Also, I think she needs to breath." Nabiki sweat-dropped as Serafall let go of the hug and giggled nervously while Sona fell on her butt and took some deep breaths to fill her lungs with oxygen.

"Th-" Sona took a deep breath to calm down and coughed lightly, "thank you, Nabiki. Sister, while I understand that pregnancy can mess with your hormones, please don't do that again." She had a pensive look on her face as Serafall looked upset, "...Fine." Sona whispered and opened her arms up while her face flushed as Serafall let out a squeal and jumped into her arms, hugging her little sister, who hugged her back. "Just don't hug me like you did before, okay?"

"Sure!" Serafall grinned and leaned back to look her sister in the face. "So, So-tan, are you going to join me and Ran-tan in a kinky, sexy threesome? Hmm?" Sona's face turned red as a tomato while Serafall's face got flushed as well. "I'm sure that he'll be the perfect gentleman to you and make you feel oh-so good and you won't want anyone else."

"Ack!" Sona let go of the hug and got out of her sister's embrace. "I knew I shouldn't have hugged you!" Sona ran away, running up the stairs and down the hallway.

Nabiki sighed as Serafall looked like she was about to cry. "May I suggest something?" Serafall looked at her and nodded, sniffling. "Ease up on the sexy time suggestions." She saw the Devil King start to get agitated and Nabiki grabbed her hand. "Just wait, I don't think Sona would mind the thought of you and her in a threesome, but you come across so strong that she gets flustered and I think she'd like someone who was a bit more reserved."

"...Why didn't I ever think of that?" Serafall asked as her eyes lit up in understanding and she thought about her sister and realized that Sona really did like things more mellow and structured. "I should apologize to her."

"I'm sure she forgives you." Nabiki smiled and let go of Serafall's hands. "Come on, sit down and... Oh!" She gasped as she saw Nodoka walking in from the dojo. "Auntie, you disappeared on us."

"Oh, I was just enjoying some peace and quiet is all." Nodoka smiled at her. "Plus dinner isn't quite ready yet, but I need to check on it." Nabiki nodded as Nodoka walked towards the kitchen. "Anyway, oh! Miss Asmodeus, where have you been?"

"Exploring that table with the holes in the side." Asmodeus told her. "All the holes end up in the same place, it wouldn't be a good place to hide since you'd slip all the way down and crash into a bunch of hard balls." The bronze-skinned mini-girl suddenly started laughing. "I like stuff like that, but that wasn't what I meant."

"I figured." Nodoka smiled at her. She found it surprisingly easy to not get flustered over what Asmodeus was saying, considering that even when she was younger and training to be Shinto shrine priestess, she had heard about the legendary sex Devil.

Meanwhile, at the end of the hallway, Sona was panting and blushing. "I wish that big sis wasn't so..." She paused as a door near her opened up and Ranma, wearing just boxers, walked out. Her blush increased as she saw his near nude form. "A...Ah... R-ranma?"

"Hmm?" Ranma turned and blinked a few times. "Sona Sitri? What are you doing here?"

Sona stammered a few times. "Ah, that is..."

"Hold that thought." Ranma said and turned around to walk a few doors away. "I need to use the bathroom."

"Oh." Sona said and nodded as Ranma disappeared into the bathroom and she was able to calm down. '...he's got great muscles.' Her face turned redder as she suddenly had a mental image of herself, Ranma and Serafall all on a bed with her sister and Ranma doing lewd things to her. "ACK!"

A few moments later, Ranma came back out of the bathroom while rubbing his hands with a paper towel. "So, Sona, what did you come here for?"

"Well..." Sona tried to think of anything other than having a threesome with her sister. "I wanted to speak with your father about the payment for his services?"

Ranma frowned in confusion. "Is pops being lazy with his training?"

Sona shook her head. "No, quite the opposite, he's far too effective. I had a rating game two weeks ago and, to my surprise, we managed to win without a single loss due to your father's psychological tactics and tricks. My opponent wanted to know who my team's coach was and after some discussion I realized that I was not paying your father enough for his services. It would reflect badly upon the Sitri clan if people knew that I was being stingy with my payments."

"Makes sense." Ranma nodded. "Sadly, I don't know where my pops is."

"Ah, that's fine." Sona told him. "I did need to talk to Nabiki as well, but big sis, ah..."

Ranma saw her blushing and nodded. "She came on hard again, didn't she?" Sona nodded. "She does that sometimes." Ranma turned and stopped as Sona grabbed his arm. "Something wrong?"

"Actually..." Sona said and let go. "I want to thank you." Ranma gave her a confused look. "I... I worry about her. She might be really strong, but she's got a weird personality and I was worried that someone would come along and seduce her just to get the prestige of having slept with a Devil King and not really care about her."

Ranma smiled at her and nodded. "You're a good sister, but yeah, I'm not going to just pump and dump her. I have reasons for it, but I do love how she's so silly and energetic."

"...You... You actually LIKE my sister's antics?" Sona asked, gawking in surprise and Ranma nodded. "...Really?"

Ranma chuckled. "As much as I get annoyed with Lilith's antics at times, I do enjoy them. Your sister isn't any different, really. Besides, I seem to attract crazy girls."

Sona smirked at Ranma. "Don't stick your dick in crazy."

"Too late." Ranma laughed at her. "Now I gotta get back to two of my crazies before they come out here and drag you in with us." Sona blushed as Ranma walked towards the bedroom he had been in. "Unless you want to lose your virginity that way, I suggest you leave this hallway."

Sona nodded and after Ranma went into the room and closed the door behind him, she fidgeted for a moment before finally sighing and walking out of the hallway. She blinked in confusion as she saw Lillie sitting on Leonardo's shoulders and Asmodeus standing on Lillie's head while all three stood taller than Serafall, staring her down. Suddenly Kunou came out of nowhere and jumped on Serafall's shoulders, putting the two of them taller than the three person tower. "...What's going on?"

"So-tan!" Serafall waved at her. "We're just doing a human tower, we need one more person, want to be on top?"

"Ah, no." Sona shook her head. "I wanted to actually ask Nabiki about some help with something."

"Oh?" Nabiki asked as she looked up from where she was lounging on the couch. "About what?" She asked and sat up as Sona came down the stairs and sat next to her.

"Well, remember the monsters that were rampaging in Northern Japan a month ago?" Nabiki nodded, she had Atsuko go to help Sona with them. "It turns out that there were some Fallen Angels and members of the Old Satan Faction that were leading the monsters."

"Atsuko mentioned something about that. She said something about an Angel helping out?"

"Dulio, specifically," Sona explained to her. "One of those monsters was a slime that kept splitting in half and was immune to most attacks and it kept getting bigger. We would have lost had Dulio not decided to cause an instant minus thirty-nine degree blizzard with twenty kilometer hour winds to freeze the thing so we could shatter all of them. I was left with a very stark realization." She said as she pulled out a tablet. "While I can create a lot of water and create water Dragons, I could use something to cause a large area of effect and I couldn't think of anything until today. To create a flood similar to what was used to wipe out the Nephilim."

"You want to cast a biblical-class spell?" Serafall asked as she put Kunou down. "The amount of power and control is pretty intense to get something even close to what drowned the Nephilim." She smiled at the shocked looks that she was given from Nabiki and Sona. "I wasn't there, but our parents were able to view what happened."

"Well, it's not like I want to flood the whole planet, but being able to create powerful storms, floods and even just making heavy water fall in one spot would be helpful, I think." Sona sighed and tapped the tablet and a holographic image of an extremely complex spell array appeared. "But I'm having trouble with it. Theoretically, it should work, but when I try to use it, the spell blows up in my face." Her cheeks turned lightly pink. "It's why I came over here. My peerage had to clean my apartment up after I destroyed most of it from the explosion."

Nabiki sweat-dropped heavily. "Mis-casting spells and they explode on you. Why do I have a feeling this will happen again in the future." She shook her head at the look Sona gave her. "Not you, but I was thinking that future generations of magic users will have something similar happen to them."

"Hmm..." Serafall looked at the spell array. "It looks like you're mostly correct, but there's like... Four or five parts of this array that are off." She reached out and touched one, causing it to glow before touching another four spots. "And there's these..." She double tapped another five spots. "I think that this is right, but if you change the values of the first ones, these will become inaccurate."

Sona looked at it and her eyes widened. "You're right! I didn't even realize that I did the math wrong here."

"Hmm..." Serafall tapped her chin and tilted her head. "Sorry, So-tan, but I would need to look at it more closely, I can see what's wrong, but fixing it isn't something I can do at the drop of a hat."

"Well, I can." Nabiki said as a clear keyboard was in front of her and she typed away at it. Clear cords reached out and connected to the tablet Sona had as Nabiki hit a few buttons and Sona and Serafall watched as the parts of the spell array that were wrong were cleared away and new lines and arrays were put in their place. "There. This should be what you wanted." She smirked at Sona, who stared in awe. "If you tell me what you want, I can make it happen. Still, you did most of this on your own, that's impressive."

"No, that's not..." Sona paused and she adjusted her glasses. "Nabiki Tendo, would you like to enter into a contract with me?" Nabiki tilted her head curiously and Sona elaborated. "I wish to become a teacher in the future and I would like to help create new spells that haven't been thought of before. While I can theory-craft, as you saw, sometimes I hit walls and I can't figure it out."

"Right, and my ability would allow you to figure it out quickly then." Nabiki asked and Sona nodded. "What kind of payment are we looking at here?"

"Standard pay rates, increased based on how much you need to fix any of my mistakes. Obviously I will attempt to craft the spell arrays," Sona said as she turned her device off, "on my own and practice them before I come to you. But I would like to know that I can send over what I have if I cannot fix it."

Nabiki nodded and stood up. "I have no problem with that. We can write up the contract later."

"Of course." Sona said as she stood up and shook Nabiki's hand. "If you'll excuse me..." She smiled nervously. "I should get back to my apartment. I worry what my peerage will do if I'm gone for too long."

"That bad?" Nabiki asked and Sona sighed.

"The last time I left them alone for too long, they started playing mini-golf in the apartment and accidentally broke a light bulb." It wasn't much, but Sona really didn't want to deal with that again.

"I'll see you out." Serafall said as she walked Sona out of the building. Once outside, Serafall wanted to say something before she paused and turned to walk back inside.

"Sister." Sona said and Serafall turned to see Sona looking at her with a contemplative look on her face. "I think that Ranma is a good man for you." Serafall's eyes widened and Sona smiled at her sister. "If you want, I'll be the maid of honor for your wedding."

The next thing Sona knew, Serafall was hugging her tightly and bouncing around while cheering her name. Before Sona could react, Serafall put her down and gave her a kiss on the lips. It was quick and relatively chaste, but it still had Sona blushing hard while Serafall's face was flushed and the elder Devil winked at her sister.

"I think he'd be good for you too, So-tan." She giggled in delight. "If you want to join the two of us, just ask, okay?" She turned and swayed her hips while walking back into the house.

"...ARRRRGH!" Sona yelled while turning and running away from the Saotome compound.

End Chapter 8

Poor Sona.
