While the Guardian Knight were a bit formal, Rias took out a cup of tea from her magical device.
She leisurely brewed a pot of light tea, her fluid movements quite pleasant to watch, making one feel refreshed.
"Sit down, don't be so formal."
Rias handed a cup to each of the five and said, "Hayate is a kind child. Additionally, the magic factors in this world are extremely low, and the environment is in a period of peace. Hayate doesn't have much of a pursuit for power; she prefers the titles of 'comrade' and 'family' over power."
"Furthermore, I have already modified the rampage program of the book of darkness, so you don't need to worry about being forced to fight."
Everyone was a bit surprised and couldn't help but look at Signum.
Among the four Guardian Knight, Signum was the leader.
She was not only the strongest among the four knights but also an upright knight with good character.
On the contrary, as the will of the book of darkness, their memories of Reinforce were somewhat blurred.
Reinforce' gaze, however, remained on the kitchen, her eyes soft.
So, only Signum could make the decision.
"I understand."
Signum nodded, and then everyone sat down.
At this time, Reinforce also turned her head and bowed slightly to Rias, saying, "Although I don't know who you are, I am very grateful that you modified the rampage program."
"It was just a casual effort."
Rias said nonchalantly.
"Even so, I still want to thank you; your casual action saved that child."
Reinforce' eyes were exceptionally gentle.
"After all, good children like Hayate are rare. Plus, we are friends, and helping a friend is only natural."
Not to mention a future wife.
Rias added in her heart.
The six of them drank tea together, and no one spoke for a while. The atmosphere was no longer as awkward as at the beginning, but instead became warm.
"It's ready~"
Yagami Hayate came in carrying a tray, and then Reinforce stood up and said, "I'll help too."
"Mhm, then I'll leave it to you."
After finishing the meal, the Guardian Knight gave a more detailed self-introduction.
Then came some questions from Yagami Hayate.
Everything about magic and the book of darkness.
Many things were said by Reinforce, which even the Guardian Knight couldn't help but be surprised by.
"In other words, you have been reincarnating and fighting along with the yaten no sho, and I am the current master of the book of darkness. Because the book of darkness's program went on a rampage, it was eroding my body. And this problem has been solved by Rias-chan?"
Yagami Hayate summarized.
"Yes." Reinforce looked at Rias and said, "Although it's hard to imagine that someone could successfully modify the program of the yaten no sho while it was in a locked state, that is the fact."
"Is it very difficult?"
Yagami Hayate tilted her head and asked.
"To use an analogy, my method is equivalent to penetrating a safe and directly using a pen to modify the documents inside the safe."
Rias said.
"Then isn't that quite amazing!"
Yagami Hayate understood instantly, which was why she exclaimed.
Reinforce and the Guardian Knight felt the same way.
"Um... actually, I've wanted to ask for a long time, who exactly is Rias-chan?"
Yagami Hayate was full of doubts.
Whether it was their meeting or becoming so close so quickly, modifying the program of the yaten no sho and helping her.
She didn't notice yesterday, but there were too many anomalies. Looking back now, she could sense many things that weren't right.
"I come from a world where gods and demons coexist."
Rias said, "The reason I came to this world is because something happened in this world a while ago..."
Rias told the story of Nanoha and Fate once through~
And this event had only happened a few days ago.
"I see."
Yagami Hayate said in realization, "In other words, when Rias-chan rescued Fate-chan, she wanted to meet that Nanoha-chan, and then she happened to run into me on the way?"
"Pretty much~"
Well, pretty much~
The difference was whether it was a chance encounter or not, a minor detail.
"Any other questions?"
Rias asked.
"Hmm, pretty much none."
Yagami Hayate thought for a moment; there really were no more questions that needed asking.
After a brief thought, Yagami Hayate looked at the Guardian Knight.
"Since Rias-chan has solved the problem with the yaten no sho's program, and I have no desire to pursue power, I won't force everyone to fight like your past masters did. You can rest assured about that."
Although they had already heard it from Rias, hearing it from Yagami Hayate made everyone look at each other and feel relieved in their hearts.
They felt lucky to have met such a master.
The Guardian Knight thought to themselves.
"The program of the book of darkness has been restored, so it's better to call it by its original name, yaten no sho."
Yagami Hayate looked at Reinforce and said, "Next is the will of the book of darkness... well, that name doesn't sound very good either, how about I call you Reinforce?"
"As you wish."
Reinforce said softly.
However, looking at her expression, she seemed quite satisfied.
"By the way, let's change your clothes next. Your clothes are really too strange for people in this world."
Yagami Hayate suddenly remembered something and then picked up a measuring tape.
Then came the happy shopping time.
Because Yagami Hayate hadn't been able to walk freely like this for a long time, she couldn't help but be a bit excited, which Rias could understand.
Rias did not participate in this; she had serious business to do.
Rias didn't go to find Nanoha, but instead came to the vicinity of Earth's Dimensional Sea and constructed a large-scale defensive line to protect the Earth.
Furthermore, Rias established a space station in Earth's orbit.
Later, she would connect this place with High School DxD, using Earth as a base to communicate with those magical civilizations.
As for Earth... if it were the past, this world's Earth would still have quite a bit of value for the civilizations of that world.
But now, apart from the exchange of technology and resources, being permanently stationed here would be no different from being exiled to the frontier.
Additionally, Rias would limit the permanent staff, so she wouldn't interfere too much with the Earth civilization of the Nanoha world.
As for the system issue... the Linker Core, as the energy source for mages, is not something that can be man-made.
Not only is the result complex, but it also involves the origin of life.
One needs a very high understanding of the concept of life to possibly create it.
Rias judged that in the High School DxD world, only the God of the Bible and the Satan Ajuka might be able to create it.
As for Rias, she didn't count herself, as her realm was already different.
By the time Yagami Hayate and the others returned, Rias had almost finished.
"By the way, Hayate, do you have any thoughts about moving?"
Rias asked.
Moving to a Other World along with the house, a true move.
