Training was hard, but Yuriko did it. Although her strength didn't compare to Yusuke's she could still put up a good enough fight. Yuriko was the type that jumped in and out. She never took a hit but gave a million in return to every attempt.
Ienashi was an aerial fighter. She swooped down to attack and took to the skies before she could get hurt. Ienashi also fought with a scimitar. Its sickly long blade often took her opponent's head before he or she knew it.
Their reiki was trained together. Ienashi and Yuriko, and sometimes Jirou, made the perfect team. Yuriko distracted the opponent with her compulsion, often making them forfeit before the fight started, Ienashi stayed hidden in the air to unleash surprise attacks, and Jirou took all the hate, he was the perfect tank. Jirou stood back, in plain sight, and sent reiki blasts and spells to their enemies.
Yuriko smiled as she made their dinner. It had been months since she had started her training and she had met her two closest friends. After dinner they were going to have their evening training and then Yuriko would see if she was actually a succubus.
If she was, they would work on unleashing her demon blood and she'd have to learn to use her youki from Ienashi, since Jirou was only a reiki expert. Yuriko jumped when arms wrapped around her waist. Tenderly, Ienashi pressed her lips to Yuriko's lips as a greeting.
"Good evening Ienashi. Are you and Jirou finished training?" Ienashi nodded and sat down at the table soon joined by Jirou.
"Is dinner almost ready, Yuriko?" Jirou played with his bowl already set out.
"Jeez, so impatient." Yuriko grinned and took the pot off the stove. "Here we go. Let's eat!" The three dug into the small meal and cleaned up after, putting the leftover in the cold room to preserve it.
"Now, here's to your hopefully last night of training." Jirou led them out to the forest and stopped in the usual clearing.
Ienashi and Yuriko got in fighting positions and powered up their reiki for any type of attack or defense. "What's it tonight Master Jirou?" Ienashi scooted closer to Yuriko and grabbed her hand.
"Defeat me together. I know you can, but do you know how?" Ienashi and Yuriko grinned at each other.
"You bet Master Jirou." Ienashi lunged forward, releasing Yuriko's hand, and attacked with a high kick. Before he could counter attack Ienashi was in the air and Yuriko was sending quick jabs and slashed across his arms. In seconds she jumped over his head and got a slash in on his back before he turned around and blocked her knife.
Ienashi pulled Yuriko into the air as soon as Jirou's barrage of range attacks started and almost broke Yuriko's shield. Ienashi dropped Yuriko, letting the girl attack Jirou from the air with well-aimed kicks before she too swooped in and got a good amount of blood on her scythe.
Jirou jumped into the trees and took off into the forest. In an open clearing like that, he would surely lose; he already was.
Yuriko followed, high in the branches. She jumped from tree to tree and swooped down now and then to land a kick or a punch on her master. Ienashi just followed, dodging the branches and tree trunks with ease earned after lots of practice.
Finally, Jirou stopped and sent another wave of attacks Yuriko's way. The branch she was on broke and she fell to the forest floor. Before she could regain her senses Jirou was on her, punching her non-stop. Ienashi swooped down and made a sweeping motion with her scythe, effectively dislodging Jirou.
Jirou jumped back and sent a reiki blast Ienashi's way. She dodged by going up and slashed with her scythe, making a fine line of youki fly towards Jirou. He blocked with a reiki shield, then sent reiki into the trees to attack Ienashi.
Ienashi cut the oncoming branches and flew low towards Jirou. At the last second she pulled up and Jirou, watching the bat demon, got a blade to the throat. Yuriko grinned up at him and placed her hand to his cheek.
"We win Master Jirou." Jirou laughed and sent reiki out of his entire body, knocking Yuriko away. As payback he received a long thin cut on his neck.
"Hot damn, you girls got better. I wonder how you are one on one?" Yuriko sighed.
"You trained us to fight together. Don't start making more training schedules just yet. Let's find out whether I'm a succubus or not." Ienashi flew down and landed next to Yuriko to wrap and arm around her waist.
"I wanna see if you are as well." Ienashi pressed her lips to Yuriko's head. Jirou sighed as he watched, Ienashi got really comfortable with Yuriko. He wondered what she would do when Yuriko went back to Ningenkai.
Ienashi shook her wings to get rid of the cramps from flying in enclosed spaces. Each wing was easily her own height. Yuriko grinned. She liked Ienashi's wings; they were large and soft and so much fun to play with. Jirou, hated them. He hated how large they were and how much like a bat's they were. Jirou hated bats!
Ienashi smirked at their master, because she knew exactly what he was thinking. Jirou shook his head and got back on track. "Okay brats, let's do this, I need to take a bath." Yuriko barked out a short laugh. Of course their master would only care about that.
"What do I do, Master Jirou?" Jirou motioned for them to sit down and they did. Jirou took Yuriko's hands and got comfortable.
"Okay, give me your reiki. I'll follow it to your source. If you have youki I'll find it and unleash it. This will turn you into your true form." Yuriko did as instructed and Jirou traveled to her source. Inside he found a large, writhing ball of youki. The old man felt somewhat worried for the future. What would happen if she couldn't control it?
Slowly, Jirou unleashed the red mass of energy and he felt the hands in his grow longer and more slender. He opened his eyes to see a beautiful woman sitting in front of him. Her hair grew longer and her eyes more narrow. Horns sat innocently atop her head and fangs rested at Yuriko's lips.
The only way they could tell this was the same girl was that she still wore her yellow tunic and black baggy pants. Her figure was more full than before and she was obviously taller. Jirou quickly let go of her hands and backed up.
Already, in a circle around the confused girl, the grass was dying. Yuriko was unknowingly taking the life-force of the earth. Quickly she stood and backed up from the circle, only making it larger.
"Stop moving Yuriko!" Ienashi had leaned down and grabbed Jirou before taking to the skies.
Yuriko did as told. "What the hell is going on Master Jirou, Ienashi?" The two in question looked at each other.
"You're a succubus. Succubi take the life force of anything they touch. You can limit your area of effect by concentrating on your youki. You saw where Master Jirou led you right?" Yuriko nodded emphatically. Hurriedly she tried to calm down and go to her source of youki but her speed to concentrate only ended up making the effect worse.
Yuriko's panicking hurried up the life drain going on around her. Jirou and Ienashi watched with trepidation.
"Yuriko," Jirou spoke calmly, "Breathe slow. Breathe in… Breathe out… Breathe in… Breathe out…" Yuriko started doing as told and calmed down. Once Jirou saw this he started speaking again, "Now, go to your source of youki." Moments passed in silence until Yuriko nodded. "Control it as you would control reiki. You control it. Not the other way around."
Yuriko felt the area of affect slowly get smaller and smaller until it was only at her skin. Yuriko felt the wind blowing her ankle-length hair against her legs and calmed down even more.
"Okay. I'm calm now. You guys can come down." Ienashi set Jirou on the ground and went to hug Yuriko but the other girl jumped back. "I can only contain it to my skin. Don't touch me." Ienashi pouted.
"Alright. Now I know what we should work on first. I'm gonna show you how to become a human." Yuriko gave Ienashi a confused look.
"Demons can do that?" Ienashi laughed.
"Of course we can. How else do we invade Ningenkai. Anyways, all demons have some reiki. Some have enough to actually become human. Others only have enough to look human. You're half human so you can switch between human and demon forms." Yuriko nodded and sat down, now sure the grass wouldn't die.
"How do I do that?"
"Exactly the same way you became a demon." Yuriko concentrated and they watched as she slowly became her human self.
"That was scary." Ienashi and Jirou laughed. "What? It really was!" Still the two persisted in their laughter. Even after Yuriko sent reiki balls their way they continued to laugh.
The three walked home to see a portal sitting in front of the cottage. Yuriko sighed. He training really was over. Ienashi and Jirou watched as Yuriko came to her decision. Ienashi shook her head.
"Hey, that doesn't mean what I think it does, does it?" Yuriko nodded, making Ienashi shake her head again. Yuriko shook her head as well and walked towards the portal.
"Hey, I need to come back for training, so wait for me. I'll definitely be back." Ienashi nodded along with Jirou and the two waved as Yuriko walked through the portal into Koenma's office. Standing in front of the toddler's desk were two demons.
The girl bowed and smiled at the two. "Hello there. My name is Urameshi, Yuriko." She could tell the two froze up when she said her last name. "Oh,you either met my mother or my brother. I'm guessing it's my brother since people aren't usually this hostile towards my mother." The short demon grunted and turned away. It seemed he didn't like the "human" girl reading his emotions.
"Hello, my name is Minamino, Shuichi. Just call me Kurama. His name is Hiei. He's always like this." Yuriko shared a smile with Kurama but stuck her tongue out at Hiei. The short demon glared at her.
"It's your fault. Treat others how you wish to be treated. You treated me rudely I'll be rude right back." Yuriko hmphed and looked away. Kurama looked on with a smile on his face. Yusuke's sister seemed to be nice enough.
"Now that you've all met. I'm sending you on a mission." The three looked at Koenma. Yuriko smiled at the toddler.
"Hello, Koenma sir. How have you been?"
"Fine, thank you Yuriko. But, back to the mission."
"I hope you have something to say for yourself."
"What?" Koenma blinked and there was a seething girl holding a blade to his neck.
"You took me away from important training. What do you have to say for yourself?" Koenma gulped. "I wouldn't do that. It'll hurt if my dagger digs any deeper into your neck. Now, what do you say?"
"I am Lord Ko-"
"Oh, shut it. Throwing a beginner into Makai… What do you say?" Yuriko pressed her dagger closer to Koenma's neck, bringing forth a drop of blood.
"S-sorry." Yuriko smiled happily and removed her weapon.
"Thank you! That's all I needed." Yuriko moved back to Kurama's side. "Now, back to the mission." Hiei smirked at Koenma's predicament, at least the toddler was feeling some pain. Kurama, on the other hand, noted the girl had balls despite being so polite.
"Okay. You three will be going on a mission with Yusuke Urameshi. The four saint beasts are demanding that we bring give them immediate immigration into the human world."
"Who are the four Saint Beasts?"
"I'll tell you on the way." Kurama smiled at Yuriko, the two had formed an instant friendship. "They are four of the most notorious criminals in all the spirit worlds. They were given the title saint by their followers. Years ago they were chased by a coalition of pursuers, and evaded capture by locking themselves into a booby-trapped fortress. Over time, a city formed, the city of Ghosts and Apparitions." Yuriko nodded slowly.
"I see. Sounds dangerous. So, what are we supposed to do?"
Koenma answered her, "You just need to get the whistle controlling the Makai insects."
"Makai insects? Oh, that just sucks. Did the Saint Beasts unleash them on Ningenkai?"
"You know of Makai insects?" Yuriko nodded.
"Yes, Master Jirou decided that knowledge of Makai life was important. He never mentioned the Saint Beasts though." Koenma hummed softly as he thought.
"It truly was the right choice to send you to Jirou." Yuriko nodded happily.
"It was. We should go now." Koenma nodded.
"Yes. And be careful." A portal opened between the three demons. Yuriko bowed once more to Koenma before she jumped through, followed closely by Kurama and Hiei.
