Kouh Town

Issei, groaned, he was aching all over. Yusei had been true to his word, the bastard had turned up at 5am and dragged him out of bed. Issei was now running behind Yusei who was a few feet in front of him. Issei growled as Yusei turned his body towards him in mid run.

"Another four miles to go Issei, come on, then its exercises in the park to finish. Rias wants you in shape, so that is exactly what I am going to do. Now come on, I am not even jogging full speed, you should be at least level with me."

Issei mumbled although Yusei couldn't hear it, he was certain that it was something unpleasant. Didn't Issei understand this was for his own good? Several times he had been nearly killed due to his reaction times. Once against that priest and another time against that Fallen Angel Raynare. Yusei decided to stop to allow Issei to catch up, he had a sly smile as he thought of a way to motivate his best friend.

"Hey Issei, you said that you wanted to be a Harem king right? Well how do you expect to keep up with all those women in the bedroom, if your not in shape. You don't want to to disappoint them do you? I know you have a thing for Rias."

Issei growled, Yusei was pure evil, using his own dreams against him like that. Issei started to pick up the pace, although he hated to admit it, but Yusei was right, he if wanted to be a Harem King, then he needed to get into shape, so he could accommodate all those beauties.

Issei Day dream

Issei sat upon a red velvet throne, and was dressed in a smart suit, and leading down from the stairs were several steps, and at the bottom of these steps were fully naked women everywhere. Rias and Asia was also in the crowd, along with Akeno and a few other girls from the academy.

"Oh Issei take me now, you know you want to?" Issei face broke into a huge smile as Rias straddled his lap, and then reached down for his zip. She pulled the zip down and used her hands to worm themselves into the gap in his boxers. Issei hissed as he felt Rias wrap her hands around it and then pulled it through the slot in his pants. Issei mouth watered as Rias huge breast bounced around as she rose herself up, and was about to lower herself on to Little Issei when….

"Issei look out!"

CRASH!

Issei was thrown out of his day dream, by his body hitting one of the lamp posts on the side walk. He had been so focused on his day dream that he didn't see the post in front of him. Issei fell back onto his backside and held his head. He could already feel a bump forming. Issei looked up and noticed Yusei was looking down at him, a frown on his face.

"FYI Issei, its not a good idea to have day dreams while your running, Guess it partly my fault, putting those thoughts into your head, but still you should be able to control them, not let them overrule you. Imagine if we had been crossing a road, that pole could have easily been a car. You need to focus more Issei. Come on we better get you home, that bump doesn't look to good, and while your in this condition its not a good idea to carry on." Yusei held out his hand and grasped Issei's, he then helped his friend off the pavement. Yusei held up a few fingers in front of Issei, and watched as his friend shoved them to the side.

"Look I'm fine okay, but your right, lets head home. Man how on earth am I going to explain this to Asia and my parents." Issei frowned as he noticed Yusei was trying not to laugh.

Later at the Academy

Yusei sat at his desk, and listened to the Professor teach. It was only him sitting at the desk, due to the accident this morning, Issei mum had insisted that her son stay home in bed. When Asia had learnt what had happened, she too refused to go to school and instead wanted to stay behind and nurse Issei. Yusei looked up to the clock and watched as the minutes ticked by, he was going out on a date with Akeno after school. The relationship between the two of them, had spread like wildfire, through the student body. This had caused not a just few angry glares from the male population. Yusei didn't care, all that matters was he was dating Akeno. Yusei was relieved to here the bell go. He took notes of his homework and then packed all his stuff up. He looked to the door to see Akeno waiting for him. Due to both Issei and Asia being absent, Rias had decided to call off the meeting tonight, giving all the members some free time. Yusei threw his bag over his shoulder and then left the classroom, he gave Akeno a quick peck on the lips, and then left hand in hand with her towards the School exit.

In Town Arcades

Yusei, huffed and puffed as he tried to keep up with the arrows on screen, he had challenged Akeno to duel on the dance machine, which he was now regretting. He turned his head and watched as Akeno moved with grace over the four arrows now under her feet. The woman was a monster on this, and she was racking by the scores.

PERFECT, PERFECT, PERFECT, GOOD, PERFECT.

That is all Yusei could hear coming from her screen, while his was the complete opposite.

OKAY, GOOD, BOO, BOO, BAD, GOOD,

Yusei noticed they had gathered a crowd, and right now he was being schooled by his new girlfriend. Eventually the last set of arrows appeared and Yusei did all he could to match the combo. Once the music had stopped, Yusei climbed off for a breather, and noticed Akeno just skipped off, and stood next to him smiling.

"That was fun, lets try another game, how about air hockey?"

Yusei looked towards the vacant table and nodded. He and Akeno then made their way over. He slotted a few coins into the machine and watched as the little red disc popped out. Yusei grabbed it, and then picked up one of the sliders and stood opposite Akeno. He placed the disc on the table and then hit it hard against the inside of the table and watched as it bounced from side to side towards Akeno, who used her Slider to push it back. They were neck and neck and there was only one point in it. Yusei watched as Akeno hit the disc, he was about to hit it back when his phone distracted him.

WINNER PLAYER RED

Yusei groaned as he noticed Akeno was on the other side of the table jumping around in glee, that she had beat him. Yusei pressed the answer button on the phone, he was surprised to see it was Rias.

Yusei it's Rias, we have another stray that we have been asked to take care of. Seeing how Issei and Asia are pre-occupied, I was wondering if you would step in and help us. You and Akeno need to come back to the club house."

Yusei sighed and then cancelled the call, he noticed Akeno had slid up next him, taking a sip of her drink. "That was Rias, we have to go, there's another stray, and she has been asked to take care of it. She wants me to help, seeing Issei and Asia are unavailable."

Akeno head dropped, she had been enjoying her date with Yusei, in fact it was the first real date she had ever really gone on, and it seemed such a shame to end it here. However devil duties took priority. Akeno grasped Yusei hand and then lead him out of the arcades into a quiet alley. She then used her magic to create a Magical circle, around her and Yusei. Both teens then vanished from the alley.

Club house

Rias, Kiba and Koneko, noticed the red circle appear, and watched as Akeno and Yusei stepped out of it.

"Good, glad you two could make, sorry for cutting in your date, but this needed our attention. Yusei you'll be standing in for Issei, okay everyone gather around me, and lets go." Rias waited for everyone to step into her magical circles, she then transported them to an abandoned factory building.

"It seems our stray as turned this building into her very own feed ground. Several humans have been killed and all that has been found of them is their body completely dried up, every single drop of liquid has been drained from their body."

Yusei cringed. "So it possible this could be some sort of vampire stray devil?"

Rias shook her head. "No its not a vampire, more like a spider, as the bodies were found inside webbed cocoons. It sounds like this stray is very dangerous, and everyone must be cautious. Everybody ready?"

Rias noticed Kiba had drawn his sword, and Yusei had Trinity on show. Akeno was dressed for battle, and Koneko had just pulled her fighting gloves on. "Okay then lets go." Rias lead her group into the building, she pulled open the main door, and a loud creak echoed around the building.

Yusei looked up and could see large spider webs everywhere, he could also her the sound of eight legs moving around the building. Yusei noticed Rias stepped forward.

"Felicia, you have killed your master and now you must face the judgement of the underworld. I am Rias Gremory, sister to the current Lucifer, and on behave of the Marque of Gremory, I condemn your soul to death." Rias paused as she heard hissing, it sounded like the stray was laughing at her. Suddenly her eyes widened as she saw several projectiles fired towards them. "Scatter now!"

The group scattered as more spikes came out of the darkness trying to pin them all down. Yusei had been lucky as one of the darts had landed by his feet. He noticed there was a small amount green liquid on the tips.

"Guys looks like those spikes are poisoned tipped"

Rias growled, she was getting fed up, of dodging the spikes. "Show yourself cowardly bitch! Lets see how your little poison spikes work when your face to face with me."

Rias suddenly froze as several appeared from the darkness. She had no time to dodge or to put up a shield. However before the spikes could hit her, someone had jumped out in front of her. Rias froze as Akeno body was hit several times with the poisoned spikes. She quickly rushed over to her servant side.

Yusei had seen the whole thing, and now he was pissed, not only had this bitch tried to hit Rias, but she had hit Akeno. Yusei emotions began to churn inside him, he allowed the hate and anger to consume him, and looked at Akeno as the others attempted to help her behind a shield. Yusei turned into the darkness and heard the hissing laughter. This bitch was going to pay.

"You bitch! How dare you hurt my friends and most importantly the girl I love, now you will be pay with your life. Trinity Gear awaken!"

TRINITY GEAR FIRST LIBERATION!

Yusei noticed his gauntlet was now glowing and it was changing shape before his eyes. Around the gem green scribe began to form, and metal claw FINGERS burst from the front of it.

[Congratulations Yusei, your emotions have unlocked Trinity Gear first stage, you can now use Sky Dragon Balance Breaker!"]

Yusei was suddenly engulfed by a bright light, inside the light, red armour began to slide all over his body. Once the light had died down, Yusei stood and looked down at himself, his whole body was covered in red and black armour, he looked to his arms, which now resembled the head of a Dragon which had glowing yellow eyes, and two mouths. One of the mouths were open and his armour covered hand was peeking out from it.

[This is Sky Dragon Balance Breaker, in this form, you have control over the element of lightning and your speed is unmatched. This is your first Balance Breakers, the others will be unlocked when you are ready.]

Yusei nodded he noticed a barrage of spikes were heading towards him, his huge wings on his back opened and he took to the sky, he then flew into the darkness, dodging the incoming spikes, Slifer was right, his speed was incredible and he was able to swerve and dodge all the spikes fired towards him, finally he could see a pair of eight glowing red eyes.

"Take this you bitch!" Yusei dragon head arm, began to form a powerful yellow beam of energy in its closed mouth, which was now glowing. Yusei dodged several more barrages of spikes. He then thrusted his dragon head arm forward, before shouting. "Thunder Force Strike!" The closed mouth opened and a stream of yellow energy shot from it straight towards the glowing red eyes. Yusei heard a cry and watched as the attack lit up the area around them. Yusei watched as the strays body was lit up, and then it fell to the factory floor with a crash.

Rias had summoned Asia who was now in the middle of healing Akeno, she had seen Yusei transformation and watched as he had entered the darkness on his own. She heard his cry and noticed the back of the warehouse was suddenly lit up by his attack. She then noticed a dark mass fell and landed on the floor. Rias stood up and walked towards the darkness, she used a globe of demonic energy in her palm to light her way. She soon arrived upon Yusei who was still transformed and now standing over the charred body of the stray devil. Rias gasped, the things was smoking from Yusei attack, and its body was capering away. Rias noticed Yusei stepped to the side.

"It's okay Yusei, Akeno will be fine. I summoned Asia and she healing her now." Rias watched as the head of his armour folded back, so she could see his face. She noticed the relief expression on it. Rias then turned back to the stray.

"Not only did you kill your master, but you attempted to take the life of one of my servant as well. Your crimes are unforgivable, and in the name of The Marque of Gremory, I sentence you to death, now begone!" Demonic energy engulfed the strays body, until nothing but a black scorch mark was left. Rias was blinded by a flash, forcing her to cover her eyes. Once the flash had vanished Yusei was stood in his normal clothes. The Trinity Gear was glowing.

"Wow, Yusei, was that really a balance breaker?"

Yusei looked to Rias and nodded. "According to Slifer, the spirit within my Trinity gear, told me that this is one of four breakers. Is Akeno going to be okay?

Rias smiled. "Yeah, Asia was able to heal the poison in her system, she is now just sorting out the wounds, but don't worry she will be okay. By the way good job on taking that stray down, it normally take all of us, but you beat it with one attack, impressive, just regret that your not a devil."

Yusei scratched the back of his head. "Well not yet, but in the future I might, we will just have to see how things turn out."
