Yuzu then walked back inside and grabbed Nene to talk to her privately
"Hey Nene...I need your help" Yuzu said
"On what?" Nene asked
"It's about uh...a succubus well it's about Mei" Yuzu said
"Oh okay so what do you want to know about her?" Nene asked
"Since you know about monsters...do you think there is something you know about a succubus or Mei's mother? I mean you have everything right?" Yuzu asked
"Well...there are a few documents about a few succubus that were found in the human world" Nene said
"Can you see if in those documents is about Mei's mother?" Yuzu asked
"Uh sure. Follow me" Nene said and Yuzu followed Nene into a laboratory
"Woah...what's this place?" Yuzu asked
"This is a laboratory. We research monsters like their strength, power, DNA, family, etc." Nene explained
"Wow this place looks amazing!" Yuzu said
"Alright we're here. Now let me see..." Nene opened a drawer that had folders inside.
"Now where is it? Aha! Here it is!" Nene said and pulled out a folder. Nene then went inside an office and sat down
"So...there are different types of succubus since they eat and act differently. Now Mei...um...I haven't seen her succubus side. Have you?" Nene asked
"W-well uh...y-yea kinda" Yuzu said
"Alright what happened at first when you met her?" Nene asked
"She uh...was acting very sexual and sorta seduced me" Yuzu said blushing a bit
"Well that's normal for a succubus since they seduce men...w-wait but...did you just say that Mei her succubus seduced you?!" Nene exclaimed
"W-woah relax...and yeah she did" Yuzu said
"Did you two end up...uh..."
"Doing it?" Yuzu asked
"Yes?" Nene said
"Well um...yeah why?" Yuzu asked
"Intresting...a succubus usually goes and seduces men but not women. Only an incubus can seduce females but I guess it's still normal since they're demons who seduce people and eat them up" Nene said
"Is it normal to see them right now?" Yuzu asked trembling feeling someone wrap her arms around her from behind
"What do you mean?" Nene asked
"I-I feel...her and s-see her" Yuzu said breathing a bit heavy
"Shhhhhhhh" The succubus said and rubbed Yuzu's pussy with her demon tail
"Wh-what...do you w-want?" Yuzu asked and panted heavily feeling Mei's kisses all over her neck
"Yuzu wake up!" Nene shouted and Yuzu's eyes widen and got up
"Wh-what happened?" Yuzu asked looking around
"You passed out again" Nene said
"O-oh..." Yuzu mumbled and got up
"I think I have found Mei's mother. Humans have complained about illusions or seeing things. There was this succubus actually...who would haunt these poor men and devour them. She would first seduce them and kiss them but during the kiss she should tear their tongue out and cut open their stomach and crush, pull or even mix up their organs slowly. The succubus would also be able to control or hypnotize them. That succubus can even devour monsters which was scary for some monsters...some say she was pregnant and others said her daughter got killed. Who knows but maybe Mei is the daughter of that succubus..." Nene explained. Yuzu was trembling when she heard Nene say that the succubus could even eat other monsters
"Yuzu you okay?" Nene said
"Y-yeah...but I don't think Mei is like that" Yuzu said
"Well I'm not so sure...but " Nene was interrupted by Sara
"We need Yuzu to come with us" Sara said
"Why?" Yuzu asked
"Mitsuko wants to research you and everything like your strength and powers" Sara said. Yuzu then sighed and followed Sara to the research lab. Yuzu's eyes widen seeing Matsuri sitting in a chair with a few cables attached to her head, arms, and legs
"Hey Yuzu I look weird!" Matsuri said
"Wh-what's going on?" Yuzu asked
"We'll be researching you here. Now please take a seat" Sara said showing a seat to Yuzu. Yuzu sighed and sat down while Sara started to attach her the cables that were connected to a machine
"Hey Yuzu this feels funny" Matsuri said giggling a bit. Yuzu got nervous while Sara was in the computer
"So...Matsuri what are you doing here?" Yuzu asked
"They just have been researching me and checking my strength and powers. Don't worry it  doesn't hurt or anything" Matsuri said. Yuzu sighed and waited until after a few minutes Mei and Mitsuko came in the room
"Hey Sara have you got a bit of her information?" Mitsuko asked.
"Yes boss I have researched her strength and her powers" Sara said. Yuzu blushed seeing Mei and wagged her tail quickly
"Now...I'm getting signals of something odd...hm? I think this is signals of love. The signals make her strength powerful" Sara said
"Hm? Mei...mind doing something for me?" Mitsuko asked
"What is it?" Mei asked
"Get closer to Yuzu..." Mitsuko said. Mei then walked closer to Yuzu which made her even more nervous and blush a lot
"Give her a lapdance!" Matsuri laughed
"Shut up!" Yuzu shouted blushing as her tail wagged non stop. Yuzu's eyes widen when she saw...Mei's succubus side! Yuzu then looked down but felt the succubus lifting her chin up and gave her a cold smirk. Yuzu shook her head and looked at Mei
"Hey Mei..." Yuzu said
"What?" Mei replied
"I know you know...tell me...why do I see your succubus side?" Yuzu asked. Mei looked away and sighed
"Mei tell me why..." Yuzu said
"I don't know alright? You're just seeing things..." Mei said
"No I'm not. I know you know. Why aren't you telling me the truth?" Yuzu asked. Mei sighed and caressed Yuzu's cheek and leaned closer to her making Yuzu blush
"There are things you don't know about me...there is something inside me that can scare you." Mei said
"Y-yeah...I know that" Yuzu said
"I don't think I'll be able to control myself...one day I'll go wild and have no control over this demon inside me." Mei said and kissed Yuzu's forehead
"You should stay away from me. You never know when I'll end up kil-"
"Mei...I love you and remember you're not alone. I know you have this demon inside but you can still take control. Your mother couldn't since she was a full succubus but you're half vampire and succubus. You're not only my master but my mate. I'll be there for you to protect and love you" Yuzu said smiling while wagging her tail then suddenly the alarm went on and Nina came running in
"Boss! We have a bit of company!" Nina shouted. Yuzu and Matsuri took the cables off and ran outside to see a pack of wolves using masks
"Who are they?" Yuzu asked
"Who knows but they have attacked and taken some wolves! Everyone in their positions!" Mitsuko shouted as some vampires flew in the air and tackled some wolves. Yuzu and Matsuri  jumped from the building and landed perfectly joining in on the fight.
"Wow...it looks like she's gotten stronger" A masked wolf said to Yuzu. Yuzu growled then shifted into a wolf and attacked that wolf biting her neck hard but another wolf attacked Yuzu biting her tail and throwing her against a wall. Yuzu got up and shook her body and saw Mei in front of her in her vampire form
"An Aihara!" A wolf shouted. Mei hissed and used her speed then cutted off a wolf's arm off with her wings
"End her life!" A wolf shouted. Suddenly Yuzu got up and wrapped her arms around Mei and used her energy to use shield
"Don't. You. Dare. Hurt. Her" Yuzu said sternly as her fire vampire wings appeared
"Yuzu?" A old wolf said
"H-huh?" Yuzu asked. The old wolf then howled calling the werewolves. All the wolves circled around Yuzu and Mei
"Looks like you've gotten stronger and learned some new moves..." The old wolf said revealing his face by taking his mask off
"Yuzu...come home with us" The old wolf said.
