Rin's condition left Izumi both shocked… and excited.
Inside her, there was not only Ishtar.
There was also Ereshkigal.
The three personalities kept switching back and forth, continuously hurling curses at him.
Especially Ereshkigal—she felt utterly wronged.
What did any of this have to do with her? Why had she been dragged into this mess as well?
As expected, Ishtar was nothing but trouble.
"Ahhh! Stop it—just stop already!"
"You bastard… damn it!"
"Be gentle, you idiot!!"
"I'm done with this! Let that woman deal with you herself!"
"Shut up! This is your fault for dragging me in!"
"Unbelievable!!"
After a storm of shouting and arguing, both Ishtar and Ereshkigal finally gave up.
Rather than endure any more humiliation, they chose to fuse completely with Tōsaka Rin.
If Izumi wanted to study them, then so be it.
They refused to suffer any longer.
Thus, the two goddesses merged with Rin.
In that instant, Rin inherited all of their abilities.
From an ordinary magus, she ascended directly to the level of an S+ combatant.
Looking at the utterly lifeless expression on Rin's face, Izumi checked her status through the system and clicked his tongue in amazement.

It was truly a leap to the heavens.
Unable to endure Izumi's relentless probing, the two goddesses had chosen complete integration.
Now, Rin had reached her full form.
From this moment on, she was both of them.
Izumi grinned.
"You really hit the jackpot."
"You gained the power of two goddesses at once."
Rin turned her head away, refusing to look at him.
She was in a terrible mood.
Being subjected to endless magical analysis and skill scans was unbearable.
It felt as though every secret she possessed had been laid bare.
Meanwhile, Izumi was thrilled.
At last, he understood the nature of Heroic Spirit possession.
Inside Rin now existed the spiritual cores of two Heroic Spirits.
That was why she had inherited everything.
Originally, they had always been connected.
They simply had not fully fused after crossing worlds.
But after everything that had just happened, their consciousnesses chose complete unity.
With this knowledge, if he returned to that world, he could reproduce the process.
Megumi Katō, Eriri, and the others were all waiting for power.
This method would drastically accelerate their growth.
It was the most efficient shortcut imaginable.
Izumi made up his mind.
Perhaps he should go pay a visit to the old man of the Hassan lineage.
Maybe he would be interested in taking a disciple.
After thinking for a moment, he spoke.
"In a while, let's go back to your world."
"The timelines there should have stabilized by now."
"We can stay for a bit."
Rin's eyes widened.
"You're serious?"
"You're not lying, right?"
Izumi nodded.
He had already planned to visit.
There were people he wanted to see.
And he was curious how that world had changed.
Plus, he now had a clear objective.
After hearing his reasoning, Rin immediately retorted,
"So you're planning to steal the power of Heroic Spirits?"
"Aren't you afraid they'll gang up on you?"
She finally understood why he had been so obsessed with studying her.
Izumi shrugged.
"That won't happen."
"A Saint Graph isn't the real body."
"Just like in the Holy Grail War, what descends is only a fragment."
"The spiritual core inside you is simply a divided piece of power that fused with you."
"So there's nothing to worry about."
"And I'll explain things properly."
"Most Heroic Spirits are reasonable. Not everyone is like that arrogant golden king."
He sighed.
For some reason, he had a feeling he would run into that man again.
After stabbing him twice, their relationship was probably beyond repair.
Rin, however, did not dwell on the details.
She only knew that she had become far stronger.
That alone was enough.
Suddenly, Izumi leaned closer.
"There's still plenty of time before dawn."
"You can't sleep anyway."
"Why don't we play a game?"
Rin stared at him, confused.
But then he smiled strangely.
"Do you remember our agreement?"
"The promise you made when I sent you back."
Her face turned bright red.
She stepped back.
"What are you planning?!"
Izumi laughed.
He warped space and returned them to her room.
Then he spoke without hesitation.
"Come on. Transform into Ishtar form for me."
"I'll show you something interesting."
Rin nearly kicked him.
"You shameless idiot!!"
But in the end, she still complied.
She transformed.
Izumi, of course, did not hold back.
Switching between Ishtar and Ereshkigal…
It was an incredible ability.
At that moment, the "Type-Moon industrial complex" began operating at full capacity.
Outside, however, Orario had fallen into chaos.
After Apollo, another god had been destroyed.
Ouranos was deep in thought.
As long as Izumi remained in this world, peace would never last.
For the first time in ages, the ancient god felt a headache coming on.
