Izumi had always been generous toward his own people.
As long as it was something they could use, he would never hesitate to give it to them.
Hearing his words, Rias shook her head.
"I don't need it for now. Give it to Akeno instead."
"My parents have already prepared something to enhance my power. It should arrive soon. Once I use it, my strength will probably reach S+."
"But Akeno… she's still not there yet."
As she spoke, Rias looked at Akeno with a helpless expression.
Akeno refused to accept the power of the Fallen Angels. Even when Baraqiel had come to visit, she had driven him away.
Because of that, it had become extremely difficult for her to improve her strength.
Hearing this, Izumi glanced at Akeno and sighed inwardly.
He naturally knew about her past.
After thinking for a moment, he spoke.
"Leave it to me. Akeno, you can stay here for the next few days."
"And Koneko too."
Perfect. He could strengthen both of them directly.
Hearing this, Rias visibly relaxed.
With Izumi handling it, there would be no problem. She was confident Akeno's strength would quickly catch up.
"In that case, I'll leave it to you."
After saying that, Rias bowed deeply to Izumi.
Once everything was settled, she and Sona quickly left.
Her next task was to return and enhance her own power.
The item her parents had sent had already arrived.
After they left, Izumi turned to Asagi Aiba.
She stopped what she was doing.
"I've finished developing the CAD."
"Is there anything else you need me to do?"
She had stayed at Izumi's house for this very reason.
Hearing this, Izumi directly took out a blue cube and tossed it to her.
"Study this."
"This is the Moon Spirit Crystal. It's also a supercomputer."
"It contains a vast amount of information. Use it to enhance your strength."
"With its computational power and database, developing powerful magic won't be difficult."
"In fact, I hope you can develop a virus program. When we face the EXE world, it'll be very useful."
The Moon Spirit Crystal was something he obtained after integrating the Type-Moon world.
Its full name was Moon Spirit Crystal – Autonomous Calculation Device.
It was an extremely powerful artifact. It could completely simulate all life on Earth, predict the future with incredible accuracy, and record humanity's history, thoughts, souls, and ecosystems.
It was both a massive database and an observation device left behind by an alien civilization.
After countless years, it had evolved into its current form.
If Asagi could truly utilize it, she would become Izumi's greatest support.
When Asagi received the crystal and heard his explanation, she was shocked.
Instinctively, she activated her Sacred Gear and attempted to hack into it.
But she was immediately repelled.
Seeing this, Izumi twitched his lips.
"Oh, I forgot to tell you. You should study it somewhere else."
"This is just a miniature version. Its real body is enormous."
With that, Izumi directly transferred her into his personal world.
He also had Alaya and Gaia assist her, allowing her to study the crystal.
Now, their authority was second only to Izumi's.
They controlled the entire world.
After sending Asagi away, Izumi couldn't help but feel anticipation.
If she could truly harness the Moon Spirit Crystal, it would be a tremendous surprise for him.
Next, he began arranging other matters.
Since war was approaching, he needed to deploy his forces.
The battleships he had been planning were also ready to be manufactured.
With that in mind, he first asked Megumi Katō and the others to return home and bring their parents into his small world.
Only then could they fight without worries.
Not only Megumi, but he also told Kanon to return home.
She no longer had parents, but she still had her little niece.
After sending them away, Izumi began handling Akeno's enhancement.
It was simple.
He took out a Heroic Spirit Spirit Core and pressed it onto her.
Seeing his action, Akeno blushed.
"My, my. Kouhai-kun, you're quite impatient."
"It's still daytime, you know. That won't do~"
Hearing that, Izumi rolled his eyes.
"What are you thinking about?"
"Focus and feel this power."
"This is the power of a Heroic Spirit!"
He lightly knocked her on the head.
Did she really think he was that kind of person?
Honestly.
Akeno blushed even more but obediently focused on the power flowing into her body.
The Spirit Core he gave her belonged to Nikola Tesla.
The power of this King of Lightning was perfectly suited to Akeno.
Especially his Noble Phantasm, System Keraunos.
It matched her perfectly.
After all, Akeno was already an expert in lightning.
Once the Spirit Core was integrated, Izumi sent her to the Type-Moon world.
At the same time, he asked Gaia to bring Tesla over to guide her training.
After finishing this, Izumi looked at Asia, Ophis, and Avrora, who remained in the room.
"Ophis, help Asia improve her strength."
"She needs to master her power as soon as possible. We won't have time to relax anymore."
Ophis tilted her head and nodded.
She had no objections.
She directly grabbed Asia and headed into the room.
In the end, only those who didn't need immediate enhancement—or couldn't improve further for now—remained.
Izumi let them do as they pleased and returned to his own room.
He began tinkering with his system.
He needed to exchange for what he required.
Ideally, he wanted another Sun Authority.
That way, he would have greater confidence in the coming war.
With that thought, he continuously took items from the Type-Moon world and threw them into the system.
This system was the true foundation of his rapid growth.
Among the items were numerous Heroic Spirit cores and various unique Type-Moon artifacts.
Even some alien technologies.
As a large number of items were absorbed, the system quickly produced what he needed.
Izumi didn't check them immediately.
Instead, he continued feeding more items into it.
Now, almost everything from the Type-Moon world could be exchanged.
Except for things he could already manufacture himself.
This wave of exchanges made him incredibly rich.
Looking at the items in his inventory, Izumi couldn't help but feel excited.
