On Way To Underworld

Deep within a dimensional void, a large red and black train was making its way towards the home of Rias Gremory. It was summer vacation and everyone had been invited to the underworld for the holidays, however, there was going to be no time for lounging around and enjoy themselves. They were here to train. One passenger was not thrilled with the situation. Yusei had still not come to terms, with what he had learnt yesterday. His very existence had been erased from history. Yusei sat away from the rest of the group and just stared out of the window, there was nothing to look at, just white streaks from where the train was travelling through the void, however right now he wanted to be left alone. Not even Akeno could get close to him at the minute, he had shut everyone out. Yusei thought back to what had happened yesterday evening why he had been alone walking in the small forest behind the old school building. Ophis had appeared before him, and had given him a choice, well if you call it a choice, either way he ended up losing. In the end reluctantly he had accepted to stay on the path he was now, but that still didn't mean he wasn't angry and upset. Azazel had been given him plenty of space today, which for his own safety might have been wise, of all the people he was angry at, Azazel was top of his list.

Meanwhile on the other side of the carriage Rias and Akeno was in the middle of a discussion revolving around Yusei. Both kept having a quick glance over at him, however soon as they noticed he had seen them, they had inverted their gaze back to each other.

"I am really worried about him Rias, I have never seen him act like this before." Akeno kept her head down and her hands were placed on her lap, seeing the boy she loved like that was really hurting her.

Rias took her best friend hands into her own. "It will be okay Akeno, he most likely still in shock, why my brother never told me beforehand I never know, but soon as we get home, him and I are going to have some serious words. Yusei may not be a Devil, but he is part of this family as much as anyone else. You should have heard the dressing down I gave Azazel last night, he was lucky I didn't do more then burn him.

Akeno blinked in surprise. "So that's why his arm is bandaged up, and he has kept his distance. I was wondering what had happened, still I can't imagine how it would feel to have your very existence erased. If it had happened to me, then I most likely would be in a worse condition then Yusei. Oh I forgot to ask how did the whole moving in go? I bet Issei parents were surprised, with having another guest board with them."

Rias looked over to her best friend "Well I slept with Issei last night, however we were not alone, Asia crawled into bed with us in the middle of the night, when I woke up, we got into a little argument, I had to remind her who was in charge and who's soul Issei belonged too. Of course Issei just laid their completely confused and just watched us throw pillows at each other. Xenovia came in a hour later to see what all the noise was about."

Akeno smiled. "You need to lay claim to Issei quickly Rias, with Asia and Xenovia in the wings, you have quite a bit of competition, you need to claim him first, then you can cement your place as number one. Yusei and I have already done it."

Rias pouted. "I know, and you keep going on about it. I remember your face the morning after, I have never seen such a large smile before. Was he good then?"

Akeno nodded. "Well to be honest it was both our first time, but he made it really special for me, if you really want to know how good he is, why don't you try him yourself. After Issei of course."

Rias grinned. "I might take you up on that offer, why don't you see if you can talk to him, its been a little while since we boarded the train, maybe he has calmed down a little. I'm going to check on Koneko, she been a little under the weather this morning, and I am not sure why."

Akeno sighed. "Well seeing how she feels about Yusei, then I can understand her being a little down, she normally holding his hand, or sitting in his lap."

Rias shook her head. "No something else is the cause, although the situation with Yusei can't be helping matters." The two girls then separated, Rias headed over to Casper and Koneko, while Akeno cautiously made her way over towards Yusei. Akeno was nervous, she had never seen Yusei like this before, and that scared her a little, however she was his girlfriend so she considered it her responsibility to support her boyfriend through whatever he was having trouble with.

"Yusei, you mind If I sit here with you? We haven't spoken since yesterday and I am a little worried about you. We all are."

Yusei looked up into the beautiful face of his girlfriend, he could see it in her eyes that she was worried. Yusei moved over allowing Akeno to sit down next to him, the couple stayed silent for a few minutes before Yusei spoke.

"I am sorry Akeno, they way I have been treating you and the others, it just hard for me, to get my head around what has happened. To anyone outside this train, I don't exist, all the memories I shared with those outside of this train, are lost to those individuals. Heck my own parents don't even know they have a son, after my walk last night, I took a quick trip to my old house. My parents were in. Somewhere in the back of my mind, I wanted to believe everything that had happened wasn't real, that they would remember me, however when they answered the door, they looked at me, like a complete stranger, I had to make excuse I had the wrong house."

Akeno moved in closer and wrapped her arms around Yusei, who in turn wrapped his own around Akeno. "So where did you stay the night?"

Yusei broke the hug gently. "I spent the night at the park mostly, I couldn't sleep, Hence the state of dress this morning. I popped over to my new address this morning and found everything had been sorted for me. I didn't have time for shower, I just grabbed a load of clothes and stuffed them into my rucksack and came to the school where we were all meeting."

Akeno was about to say something, however the train suddenly jerked and halted, sending everyone inside the carriage flying. Akeno quickly recovered, what on earth could have caused the train to stop like that, she looked around the carriage and noticed everyone was recovering, however Rias was no where to seen. Suddenly train began to de-materilised and everyone screamed as they all began to fall to the land below. Luckily the train wasn't that far off the ground, so no one was seriously injured, however the impact of the fall still hurt. Akeno attempted to stand up, along with the rest of the group, her vision was a little distorted due to a cut in her head, and the blood was now trickling down her face. She was able to make out a huge shape heading towards them. Where the hell was Rias? As the queen it was Akeno job to step up when Rias wasn't around. She noticed everyone had now got to their feet, and were stood with her. The shape had finally come into focus, it was a huge black and purple dragon, the creature let out a huge roar, that uprooted the ground around everyone, forcing them all to the ground.

Meanwhile on top of the cliff hidden, Rias and Azazel watched on, she wasn't too pleased with this idea, however Azazel had convinced her it was necessary to see exactly how they all did without her. Apparently Azazel felt she was too laid back, with them, and this was causing lack of judgement on her part. This would be the first time that she wouldn't be part of the group, and she too was curious how Akeno would do in leading the rest of their family. Rias watched as Akeno stood her ground and quickly transformed, she then began to issue orders to everyone else.

Koneko was trying to prove that she belonged with Rias, and she charged towards the huge dragon, she scaled the steep canyon cliffs and jumped, with her fist ready to hit the dragon in the face. However the dragon was ready, and with its huge hand, it swiped her away like a bug. Koneko back slammed into the canyon wall, she winced in pain as her head hit the hard rock, and her vision became distorted, she had failed again. Koneko closed her eyes and allowed Darkness to over take her, she wouldn't hold the rest of her family back any longer. She had promised never to use the dormant power within her, as it had sent her sister mad, which had lead to her sister killing her master and leaving Koneko alone. Once her sister had abandoned her, she was made into an outcast, no one wanted anything to do with her, she was constantly picked on and made fun of. It was only when the current Lucifer Sirzech found her, that her life changed a little for the better. She was taken in and given a food and nice warm bed, however her past experience had left her rather traumatise and she hardly ever spoke. This was why she was so withdrawn, she still found it hard to make friends and to open up to people. As Koneko drifted off into the darkness, she recalled the day that she had met Rias, and learnt that Sirzech was her older brother, and that he was placing her in the care of Rias, as one of her Rooks. At first Koneko again was withdrawn around Rias, however eventually the more she came to know about Rias, the more she began to open up. Rias was the big sister Koneko had always wanted, she was always putting herself out and making sure that everything was okay. Koneko suddenly opened her eyes and felt weightless, it was then she noticed she was in the arms of someone. Koneko looked up into the face of a very determined Yusei, had he saved her from her fall?

Meanwhile Issei was having problems with his sacred gear, for some reason it wasn't activating fully, he had hoped for his scale mail armours, but instead he had been left with just his gauntlet, that was now slowly boosting. Akeno had told him to stay in support, and when his gear was fully boosted, then to transfer his power to one of the knights, who was busy parrying the dragons huge tail. Issei growled in frustration he could do so much more, but until his gear boosted he was pretty useless. Issei looked to the cliff and watched as Yusei caught Koneko and landed with her. She was then handed over to Asia, who helped her away from the battle, so she could heal her.

Yusei was relieved that Koneko was save, he surveyed the battle field and noticed everyone was doing their best in fighting off the dragon, even little Casper was using his sacred gear to try hold the dragon in place, however it was doing little good. Yusei looked up and noticed Akeno was now using her magic to strike the dragon with a number of elemental attacks, but they seem to be having little effect, he could also sense that for some reason Akeno wasn't using all her power, and she was holding back for some reason. Yusei watched as the dragon unleashed a flame that Akeno attempted to block, however her shield shattered and she began to fall. Yusei growled and raced across the battle field swiftly, he just managed to dive and catch Akeno in his arms. This dragon was going down, he had hurt no only Akeno but Koneko too. Yusei stood up and marched towards the dragon who was now looking at him.

"Obelisk Manifest yourself now, tear this dragon apart with your bare hands. I sacrifice a portion of my life force as payment for your unsealing."

Yusei noticed his gauntlet suddenly shone brightly, as it did a dark blue light left the gauntlet and hovered behind him. The light began to expand into a shape of a huge creature. Slowly Obelisk began to materialise until eventually he was stood tall behind Yusei, he extended his huge wings and slammed his huge blue fist together and roared, again uprooting most of the surrounding area.

Azazel looked on, so this was the power of an Egyptian God, Azazel could feel the tremendous power from where he was standing, even Rias was speechless at what Yusei was able to do. She never realised Yusei had this much power at his disposal. The ground shook violently as both titans went at each other. Azazel watched as Obelisk threw his fist forward, which was blocked by the dragon forearm. The punch had caused the dragon to slid back a few feet. Azazel knew this was training exercise, after all the dragon was only testing them, and was using and tenth of his overall power. Still this God was worth keeping an eye on, Azazel wonder if all the Gods in Yusei gear could manifest like this. Having seen enough, he made himself known and both the dragon and Obelisk stopped their attacks.

"That's enough, this battle is over. Tannin thank you for your assistance. Everyone what you just faced was the first part of your training. During the battle I was able to get a rough idea what each of you need to reach your full potential, and I will discuss that further at dinner tonight. Also be aware Tannin was using only a small portion of his overall power just now, so with that said, I can see plenty of room for improvement."

Yusei gritted his teeth, so all this was some test, so Azazel could get a jest of where they were in their abilities and what training was needed. Meaning he had used his most powerful ability at the cost of his life force for some stupid test. Yusei felt like ordering Obelisk to attack Azazel, but knew that wouldn't go down well. Still he was upset that Azazel would allow both Akeno and Koneko to suffer the way they did, just to prove some point.

Hot Spring Resort

After the battle Rias had apologised to everyone, and made them aware that this whole battle wasn't her idea, and that Azazel had forced her into it. This had just made Yusei even more upset, and now he was sat as far away from the fallen Angel as he could get. The hot spring was on two levels, the upper level was the female baths, the lower level was the male baths. Issei was trying to stretch his neck to see above but the distance was too much, he could just imagine the show he was now missing, with both Rias and Akeno melons on display. Issei was suddenly disturbed by Azazel.

"So Issei, how far have you got with Rias, tell me have you been able to get a feel of those two huge bean bags of hers."

Issei was surprised at the topic of conversation, however he decided to answer. "Not really, had a feel, just the occasional brush against them, although I have had my head firmly between them several times. Its heaven on earth."

Azazel threw his head back and laughed. "I've seen bigger trust me, if you ever get a chance to visit Heaven, you should check out the bust on the angel Gabriel, now those are some big melons. Easy a J cup, you don't know how many angel have fallen, just from simply having perverted thoughts about her and her weapons."

Issei eyes widened, J cup, hell yeah he would have to check those out, still right now he was on mission to get hold of Rias and her huge melons. Both was disturbed by Yusei getting out of the bath, he had heard enough, no way was he going to sit around her and listen to Issei and Azazel talk about breasts. Beside he had already got plenty of experience with groping Akeno breasts, Yusei wondered if Issei would pop a blood vessel if he knew what he and Akeno had already done.
