Arriving in the Hanging Garden of Babylon, there were two guests who had appeared inside this place.
"Oh-ho, so this is the one which is known as the strongest human."
The one who had said it was the former of Dragon King, Tannin.
fifteen meters tall, gigantic western Dragon, and while also standing using two of his legs.
Tannin was looking at Yuuki curiously since it was his first time seeing such a strong human.
"Yo, Crom."
Yuuki greeted someone that he was familiar with in the past.
"Let's have a duel," Crom Cruach said.
Crom Cruach was the dragon that Yuuki had met in the past and fought for a while. He didn't show his dragon appearance, but only using his human appearance.
"I'm busy, maybe next time," Yuuki said.
"Ok." Crom Cruach nodded.
"...."
Tannin was surprised by their interaction.
"What's wrong? Did you call me because both of them come to this place?" Yuuki said.
"That's right, nyaa! They wanted to entrust something to Ophis," Kuroka said.
"Entrust something?" Yuuki was curious while looking at Tannin.
Tannin smiled and showed them an egg. "This is an egg from Spectre Dragon. It has been a while since such a rare thing was born to this world, and I want you to take care of this egg for me."
"Why?" Vali asked. He didn't really understand why Tannin wanted to leave this egg to them.
"Because the air in the underworld is not suited for hatching the egg, and you guys are the only ones who are strong enough to protect it," Tannin said.
"...."
They looked at each other then noticed Ophis who looked at the egg curiously.
Tannin looked at the inside of the Hanging Garden of Babylon and asked, "Did you build this flying fortress yourself?" He looked at Yuuki in surprise since he knew that this flying fortress was very powerful.
"Yes."
Yuuki nodded in response. He looked at Ophis and asked, "Ophis, do you want to take care of this egg?"
Ophis looked at Yuuki and nodded. He was hugging the egg carefully showing that she would take care of this egg herself.
"..."
Everyone looked at each other since it might be the first time they saw Ophis to show what she wanted to do.
They looked at each other and weren't sure what to do for a while. Then they looked at Yuuki for some reason.
"Well, just keep it if you want it," Yuuki said.
Ophis was expressionless, but for some people, they could see that she was really happy with her body language.
"But is it alright to keep it here since we have often gone out," Arthur said.
They knew what Arthur meant and that was they were too worried to leave the dragon egg to Ophis.
"If it's in Asia then it's good," Yuuki said.
"Why do you need to mention Asia-Chan here, nyaa?" Kuroka asked.
"Because she is a very talented dragon tamer," Yuuki said.
Tannin nodded and said, "I have also heard that beautiful young girl who has even tamed Fafnir and other Evil Dragons who have been reincarnated by Qlippoth."
After the attack of Auros, there were a lot of Evil Dragons who had gathered around Asia and all of them started to become closer to her as if they wanted her to tame her.
Yuuki was also surprised at that time, but when he thought that this girl was the girl who had tamed one of the Five Dragon Kings, Fafnir. He didn't think much and thought that everything was possible.
Ophis who heard their conversation thought that she might not have a chance to take care of this egg and showed a bit of distress. Even though she was expressionless, her body was slightly hung and felt confused about whether she should place or take the egg.
Everyone who saw Ophis couldn't handle seeing Ophis have such a reaction and even Vali who usually only cared about a fight was also quite troubled to see Ophis have such a reaction.
"You can take care of the egg," Tannin hurriedly said since he didn't expect for Ophis to love it that much.
Ophis nodded and sat down on Yuuki's lap while bringing the dragon egg. Her head turned upturn then looked at him for a long time.
Stare!
Ophis kept staring at Yuuki without saying anything.
Yuuki sighed and patted Ophis's head. "If you're worried about the dragon then take it to my house since my place is very safe."
Not that he was arrogant, but his barrier was strong and its defensive system might be among the strongest in the supernatural world. It also used emotion detection to detect its enemy as long as someone showed hostility, anger, and every negative emotion then they would disappear.
If someone is strong enough then they might be able to hold on for a while and use that chance to run away, but if that someone is as strong as Sirzech or one of the top 10 strongest beings in the world then this barrier could buy him time to come back.
Ophis nodded and hugged the dragon egg.
"......."
Everyone didn't know why but when they saw Ophis who was hugging this dragon egg, they felt that their heart turned very peaceful and wanted to hug her for some reason.
"Let me hug you, nyaa!" Kuroka said.
"M - Me too!" Le Fay said and walked toward Ophis.
Jeanne also walked toward them since she wanted to tease this cute dragon.
Walburga, the newest member, also joined in.
Arthur, Bikou, and Vali decided not to do anything since it wasn't their style to hug someone.
Yuuki brought Ophis along with the egg to his house, but suddenly he received another call and this time it was from Rias who told him that the group of exorcists had come to her city to challenge them.
"........"
Yuuki thought the climax was also here and went to the top of Hyodou residence where everyone was gathering.
Michael who was the leader of Heaven also appeared on the visual screen seemed to be very regretful and apologized about what had happened.
Yuuki was right the group of exorcists who had come to his town earlier decided to go to Kuoh and sent out a challenge letter to them.
"I'm sorry about what has happened, I'll do something about this," Michael said.
"Well, Michael, calm down," Azazel said.
"Have they come before?" Yuuki asked.
"Yes, they've come at us before," Issei said.
"Are they strong?" Yuuki asked. He wanted to know how strong was the group of an exorcist.
"Very strong," Kuroneko said.
"Stronger than Evil Dragon?" Yuuki asked.
"..."
They didn't answer it and didn't think that the group of exorcists would be as strong as a group of Evil Dragons.
"Well, the problem is what are you going to do with this challenge letter?" Yuuki asked. He didn't understand why they didn't catch all of the members of the exorcist before, but it might be because of the plot.
"I'll stop them and use the power of Heaven to catch all of them," Michael said since he knew that it was his fault to not realize the identification among the exorcist on the church. What even surprised him was the leader of that rebel group was the number 2nd, 3rd, and 4th on the church making him very sad.
"The first thing you need to know is that having Heaven to send a deterrence to those groups won't stop everything and there might be another rebel happening in the church," Azazel said.
"So you want to accept their challenge?" Yuuki asked.
"That's my intention." Azazel nodded and asked, "Rias, what do you think?"
"If it's the best way, then I'll do it," Rias said.
Rias's peerage who heard it also supported Rias's opinion.
Sona, along with her peerage, also agreed to join the fight.
Dulio and Tobio also joined this fight.
Dulio joined because he wanted to stop his teacher who also joined this rebellion.
For Tobio, he was a subordinate of Azazel and if Azazel told him to join this battle then he would join.
His relationship with Tobio was quite awkward, but he had a very close relationship with Suzaku.
Yuuki might not give back the Vermilion Bird of the Himejima clan, but he was laxer toward that clan compared to the other clan since Tobio and Suzaku had come to him before after the concert.
But for this fight, Vali, Yuuki, and along with their group didn't join since it would be overpowered.
Dulio had a power that was enough to cause world destruction and their enemy was only a group of an exorcist.
Vali, who was eager to fight the strong, thought that it was better to fight something stronger.
Yuuki also didn't have the interest to fight them either and fought a group of humans that he had never seen before would cause a bad taste in his mouth unless they did something to his family or his acquaintance. From the image of the reader, he might be quite cruel, but he had often given a chance for a people for redemption to try to not provoke him and he also wouldn't attack someone unless they had provoked him.
But if they kept annoying him then he didn't hesitate to end their lives and the group of exorcists wasn't included on the list of a group that he needed to end no matter what.
Kuroka, Le Fay, Jeanne, and Bikou didn't have an interest, but Arthur decided to join them since he was curious about the previous wielder of Durandal.
However, it didn't surprise them since Arthur was known as someone who loved the sword very much and the previous wielder of Durandal was very strong.
From Issei's description, even though this person was old, his body was very large and huge.
"His hand is as big as a tree trunk," Issei said in an exaggerated way.
For this alliance, no one would force anyone to fight since Azazel also didn't even ask Sairaorg and Seekvaria to join this fight since he was afraid to cause an identification on the Devil side.
"Where is the location of the fight?" Issei asked.
Yuuki looked at Rossweisse who gave him a nod.
"I have prepared a seal for 666 and it is also a good way to test the power of the seal....." Rossweisse told them about the seal that she had prepared that would able to create an artificial place around 10 kilometers.
Everyone was surprised when they heard it and thought that Rossweisse was a genius.
Azazel nodded and said, "Thank you."
Michael felt very grateful to everyone and told them to be careful.
After the meeting, everyone would be prepared since the battle would start tomorrow.
Yuuki decided to go back, but he was quite curious about the room that was created by Heaven to make the angel wouldn't turn into fallen when they were having a dirty thought or intercourse. He was quite speechless when he had heard Issei only used that room for a toilet to escape from the attack of Irina.
Yuuki entered the room and wasn't sure what to say for a moment since the mood that was given by this room was quite weird.
There was a huge bed in the middle of this room along with canopy on the top of it, however, it was surrounded by a lot of religious items in its surroundings making someone who entered this place would focus on those items even if they didn't want to too.
"What do you think of this room?"
Griselda suddenly entered the room.
"It's quite weird," Yuuki said in his honest opinion. "Does it work?"
Griselda thought for a while and said, "I'm not sure, it is said that it is working, but no one has ever tried it before."
Yuuki looked at Griselda and felt quite weird for some reason. "It's quite troublesome...."
Griselda smiled and asked, "Do you want to try it?"
"I have the intention, but I don't know any angel or reincarnated angel," Yuuki said with a sad expression.
"Then, do you want to try it with me?" Griselda asked.
"........"
"It's so sudden," Yuuki said.
"I have never thought that you're a human, and it is also a good chance to test whether this room is working or not." Griselda looked at Yuuki and asked, "Or you don't have an interest in this old lady?"
"Old? No, from what I can see that you're in your 20s," Yuuki said.
"Thank you." Griselda was happy with her praise and said, "But it is alright to ask some request before we try this room?"
"What is it?"
"Please keep it a secret from Xenovia since I want to maintain my image as her good mother," Griselda said.
"...."
Yuuki looked at Griselda for a while and nodded. "I promise you."
Griselda smiled and took off her nuns uniform slowly.
The room was located quite far away so it wouldn't cause a disruption on the people who decided to use it.
Yuuki was also the same and his little brother had been very eager.
Griselda held both of her hands as if praying for something, then looked at Yuuki with a very soft yet couldn't wait for it to happen while also secreting a mature pheromone from her body. Her eyes were looking at the holy sword on his body.
Yuuki couldn't handle it and brought her to the bed to test whether it was soft enough or not.
"Please slowly since it has been a while...."
"Don't worry, I'll be very gentle....."
