Alex woke up, and the first thing he did was untangle himself from the limbs in his bed as usual. It had been a while since the attack of the conference, and now it was time for them to leave for the underworld during summer break. With his waking as the signal, the other three people on the bed started waking as well.
"""Good morning Alex.""" Alex didn't know what it was, but having three naked beautiful women say good morning while getting up from the same bed made him feel satisfied. Xenovia especially, after the conference when she became able to pray again, started trying to appeal to Alex more. He knew that she was doing so because unlike before where the only concern was getting pregnant, she now started developing feelings for him. They made their way downstairs after dressing, and Akeno started making breakfast. During breakfast Rias made the announcement,
"Today were leaving for the Gremory territory in the underworld. I already sent a message to Kiba and Gasper, and they'll meet us at the train station around noon." Everyone acknowledged her words. Before going back to eating. Alex looked over and saw Koneko sighing and looking a little depressed. He recalled that she was depressed around this time because she felt like everyone was leaving her behind in terms of capabilities. He already decided to work on his strength and combat during the training, and thought that Koneko might make a good training partner. He could also use the chance to make her accept her heritage that she kept trying to reject.
After breakfast everyone left to the train station, only to meet Kiba, Gasper, and Azazel. Azazel became a teacher at the school right after the conference, in order to train them in using their sacred gears. He was also going with them to the underworld for business while they were there. Rias led them to the Devils underground station, and they boarded the train to depart. During the trip, Alex was sitting still and trying to focus on his surroundings. During his fight with Vali he had to close his eyes due to the full moon, and became defenseless because of it.
He knew it was possible to sense his surroundings in such a way that he didn't actually need to see, but he never trained this so he decided to start now. The girls saw him seriously training and decided to leave him alone. This was also why he thought Koneko would make a good partner, as a user of senjutsu, which was essentially this worlds ki would help him be able to sense it better. He also hoped to train in touki in order to increase his physical capabilities. When she noticed what Alex was trying to train, Koneko gained a conflicted look because she was constantly trying to avoid using this power.
After an hour of traveling, they finally arrived at the Gremory territory. Alex opened his eyes for the first time, and follow the others out of the train. There was an entire crowd of people waiting to receive them, with both servants and soldiers. As they stepped off of the train a chorus of welcomes sounded out and fireworks were shot off. They here herded into some carriages, and they headed off to the Gremory castle home. As they exited the carriages, a familiar silver haired woman greeted them.
"Welcome home lady Rias and Alex, and her peerage members." After Grayfia finished her greeting, a small boy ran over.
"Sister Rias! Welcome home!" Rias picked up the small boy and hugged him, while also greeting him. She then turned to Alex and said,
"Alex this is Millicas Gremory, my brothers son and the heir next in line after me. Millicas, this is my boyfriend Alex." Millicas looked at Alex and said,
"Nice to meet you Alex, I am Millicas Gremory." Alex smiled at him and replied,
"Nice to meet you Millicas, I hope to get along with you as your future big brother." Millicas smiled at Alex's words, and turned back to visit with Rias. After that they made their way to the main doors of the castle. When they entered there was a beautiful woman that looked the same age as Rias walking over to greet them,
"Welcome home Rias." Rias smiled and replied,
"I've returned mother." After they greeted each other, her mother looked at Alex and smiled while saying,
"It's a pleasure to meet you. I'm Rias's mother, Venelana Gremory. You must be the young man who interrupted the engagement party and made off with my daughter, Alex." Alex smiled back at her and said,
"Indeed, it's a pleasure to meet you as well. I am Alex, the current red dragon emperor, and Rias's boyfriend." Venelana looked pleased at Alex's introductions, and then asked,
"Have had any training in high society Alex?" He shook his head.
"None, but I am aware that I would have to know in order to avoid embarrassing Rias in front of the other high society Devils." Venelana nodded her head and looked at Rias approvingly, as if to say the man she chose wasn't a total loss.
"I'll arrange it so that you can take a few lessons while you're here, dancing, eating, and a few others for the future." Alex nodded as he didn't want to cause an argument, and he figured he would have to try to work out a schedule to maximize his training. He also figured that some of the things he would learn would be useful in the other worlds, as the etiquette is usually similar.
After they got settled, they had dinner together and finally the day came to an end.
