Back in Chojusen's original universe, within his personal dimension, Kaguya, Ino, and Karin were standing before Chojusen's true body with faces of concern. They all saw Chokogo forcefully enter the void and teleport outside even Karin's range of detection.
After they told Chojusen what was happening, they waited to see how he would respond. Chojusen was currently talking with the system before he made any rash decisions. Chojusen said "So you're telling me that Chokogo was summoned by the avatar to be his familiar? She's completely safe? And she even managed to evolve into a Fiendgod Empress?"
[That's right. You have no reason to worry. Chokogo is in safe hands. The last thing you want to do right now is summon her back, as that would throw this universe out of order and the system of energy in her body would cause her to die.]
"Still, it feels kind of odd without her around…"
[Well, you won't be sad for too long, as your avatar is gaining strength quickly. Currently, he has energy levels comparable to peak-tier Jonins. Once his energy reaches the Demi-Immortal Rank, you can establish a connection through your two personal dimensions and travel between universes without risking universe annihilation.]
"Oh? What about the others from this universe? Can they stay in here with the connection active?"
[Of course they can. Actually, as soon as your avatar reaches the Demi-Immortal Rank and creates the connection, this personal dimension will have both universes' energy systems. What this means for you is that all the people that stay in your personal dimensions will be "gently" baptized by your personal dimension laws and gain the higher universe's energy system. They can then travel to the higher universe without needing an avatar.]
"Wow, so you mean that my friends and family can continue past the Immortal Rank like me?"
[Just count it as a perk of having me — system-kun~]
…
In the higher universe, Chojusen's avatar was currently listening to the system explain the conversation it just had with the true body. He was so focused that his body functioned on auto-pilot. The last thing he had in mind, before the system started talking to him, was to go take a shower, so he mindlessly made his way over to the bathroom.
He took off his clothes and entered the showering area, completely unaware of the sounds of bath water running. As he entered the shower, he was brought out of his thoughts after he saw that Asia was already in the bathtub. He apologized and was going to leave, but Asia pinched his arm and told him, it was fine if he stayed.
Now, Chojusen was a "Master" of Dual Cultivation, so looking at girls naked wouldn't make him go absolutely insane. However, Asia was just a pure flower; this was the first time she saw a man's body naked and the fact that Chojusen didn't mind her seeing, made her all the more choked up.
Chojusen didn't mind her childish reactions and just took a regular shower. While he took his shower, Asia said "You… you don't seem to mind being naked?"
"Huh? Oh, that? Lets just say that I'm experienced in the field of human anatomy. Ok?"
"Figures… you being a god, of course you wouldn't care about a body as worthless as mine..."
Whoa, that self-deprecating comment was hard-hitting, especially since Chojusen could see her emotions express how bad she felt. Chojusen said "Why would you say that? You have a beautiful body, just because I don't ogle at you doesn't make that fact void."
Now that Chojusen's words gave Asia a bit of confidence, she jumped at him and gave him a hug. She said "You really mean that?"
"Why would I lie?"
Chojusen's comments lifted up her spirits, but then she realized that she was hugging her god while they were both naked. She felt her head blaze as the blood rushed up her head and then slowly separated from him. Chojusen found her behavior amusing, but he didn't push her. He finished his shower and jumped in the now empty bath.
After Asia calmed down, she found that Chojusen's nonchalant attitude was comforting, and her embarrassment of being naked around him lessened; it lessened bit too quickly for Chojusen to understand… She jumped into the bathtub that was only meant for one person putting Chojusen in a compromised position; not that he complained though.
While still in the bathtub, Chojusen started teaching Asia about energy and powers. But then he quickly found a problem with Asia, preventing her from gaining strength. In their conversation, Chojusen learned that Asia was only capable of using a healing light with her Sacred Gear, Twilight Healing. She had never trained her body or energy, because she neither had access to holy or demonic energy.
To remedy this problem, Chojusen decided to add her to his peerage. But he had just spent half his Fiendgod bloodline essence on Chokogo, so Asia could either become a Nephilim or a Chaosfiend. Chojusen chose to make her a Chaosfiend as it was naturally the better bloodline; he would only start a Nephilim peerage, if the people he wished to reincarnate had overwhelming affinity with that bloodline.
He told Asia about his plan, bringing her an incomprehensible amount of joy. To Asia, reincarnating to be of use to a real god was something she could never have thought of before coming into contact with Chojusen. This was especially the case when Chojusen explained just what a Chaosfiend was.
The way Chojusen put it, a Chaosfiend was the culmination of his bloodlines put together. Reincarnating as a Chaosfiend would give her a ridiculous aptitude for Yin, Yang, Space, Time, Demonic, and Holy energy, as well as a link to the hardest energy to master in any universe; Chaos energy.
Chojusen created another queen piece from chess and infused it with half his Chaosfiend bloodline. As he reincarnated Asia, the system's prompt made him smile.
[Host has gained the new passive ability: Chaosfiend Emperor Ancestor
Chaosfiend Emperor Ancestor (Rank Novice | 0/100): A passive skill given to those that start their own Chaosfiend peerage. The higher the Rank and Proficiency of this skill, the higher the resonance between a Chaosfiend Emperor and his Peerage. Current Effect: The user can increase all aspects of his strength by a factor of five, when fighting with a member of his peerage.]
Asia's body didn't disintegrate like Chokogo, but she did gain a few runic-like grey tattoos that glowed with a golden light whenever her energy flared. The tattoos faded when her energy stabilized and the reincarnation was complete.
Like Chokogo, Asia felt a stream of knowledge enter her head. She said "I'm now a Chaos Queen?"
"Congratulations. Now, back to the magic lesson. So, for your healing skill, you want to..." Chojusen continued with the lecture on magic as if he didn't just reincarnate someone. The way he showed that he didn't care about this event, as if it was just a trivial situation of everyday life, affected Asia, as she also listened to his lecture without placing as much importance to her reincarnation as she should have.
Since Chojusen made Asia a Chaosfiend, he taught her all his healing skills as well as his Magic Body Refinement Skill so that she wouldn't be completely helpless, if for some reason he couldn't be by her side. The two of them forgot that they were supposed to be showering, so Issei's parents were getting worried after not seeing either their son or Asia in so long.
They started looking around the house and eventually ended up in the house's bathroom. The shock on Issei's mom could be imagined, when she saw that her son and the girl he brought home where playing around in the shower. Chojusen and Asia were both in their late teens, so she couldn't blame them for their hormones acting up, but this was ridiculous…
Chojusen hadn't exactly caught up with all the cultural differences between his world in this one, so he didn't exactly react "normally." If this was back in his home universe, his biological mom would just see that he was taking a shower and stop intruding, so his confusion would be easy to picture when he saw his mom look at him like someone just died.
Chojusen said "Is something wrong?"
"Is something… wrong? What the fuck?"
Chojusen knew he messed up severely somewhere, as he had recently learned how bad something was if cursing was involved.
As Chojusen thought about what he possibly could have done to warrant a curse from his own mom, Asia wished she had a hole she could bury herself in. This was her first night over in Chojusen's house, and she had already been caught taking a shower with him… Still, this was her new god, so she had to do everything she could, to help him out of this situation.
Asia said "I… I'm a foreigner, so Issei is just being accepting of my culture where men and women bathe together..."
Issei's mom said "It's a culture thing…" She more or less wanted to believe Asia, but there was still a part of her that thought Issei's past personality was starting to come back, so she passed Asia some "colorful" square plastic packets which had a circular bumps and said "Fine… But if anything "coincidentally happens," I want you two to use protection..."
Issei's mom left the bath and told her husband to not worry, leaving behind a completely flustered Asia and a confused Chojusen. Chojusen asked "What are those plastic packets?"
"..." Asia couldn't bare to speak such disgraceful word; not to her god...
