Souta immediately rejected her idea.
"As your friend, I can't just stand by and let you disappear. This is not happening."
After thinking for a moment, he proposed a different plan:
"How about this—when you go back to 30 years ago, don't destroy Mio's birth factor right away."
"First, invite me to your world. The system will transport me directly to your side."
"Once I'm there, then you can erase Mio's existence."
"And the moment you do, I'll immediately take you back to my world."
"That way, when your world's timeline changes, you won't be affected—but you'll have to live in my world from then on. If you ever return, the world's rules will probably erase you."
Kurumi's lips curled into a smile.
"Ara, ara~ Rokuhara-san, are you really that reluctant to part with me?"
She wasn't displeased—
If anything, she seemed genuinely happy that he cared this much.
"Yeah, of course I don't want you to disappear." Souta admitted openly.
"We're friends, aren't we?"
Kurumi exhaled softly, her expression relaxing.
"Friends, huh... Thank you."
"Your idea is worth considering. However... it's a shame."
"With my current time reserves, I don't have enough power to activate the 'Twelfth Bullet' and travel 30 years back."
"Oh, right—" Souta suddenly remembered.
Kurumi's stored time energy wasn't nearly enough to execute her plan.
"You Spirits... You're not actually immortal, are you?"
"If we were, I could use my Angel's abilities to go back in time as much as I wanted."
Kurumi sighed and added:
"Spirits only have longer lifespans than humans, but we're not truly immortal. That's why I have to steal time from others to keep myself going."
Hearing this, Souta fell into deep thought.
Kurumi had morals—she would never massacre innocents to gather time.
And only hunting criminals for time energy...
Would take way too long.
"There has to be a way to help her get a massive amount of time all at once..."
All of a sudden, Rokuhara Souta had an idea.
He immediately picked up his phone and called out to the system:
"System, I have a question. If we find the real-world author of Date A Live and convince him to rewrite the story, would Kurumi's world change accordingly?"
If that were possible—
Wouldn't it be way easier to just have the author add a super resurrection ability to the story?
Then everyone who had died—
The 1.3 billion casualties from the Eurasia Sky Disaster, Kurumi's friend, and countless others—
Could all be brought back to life!
That way, Kurumi wouldn't have to go back in time to change history.
However, the system immediately shot down his idea:
[When a fictional world becomes real, the relationship between the author and the world is no longer that of creator and creation. The host's method is ineffective.]
Souta clicked his tongue in frustration.
Damn, not even the tiniest loophole to exploit, huh?
Since rewriting the script was out of the question, the only alternative was to solve Kurumi's time reserve problem directly.
Meanwhile, Kurumi was somewhat impressed by Souta's outside-the-box thinking.
Most people would try to work within the established rules.
But Souta's first instinct was to flip the entire chessboard.
Just as the two were deep in thought, the doorbell rang.
Souta got up and opened the door—his takeout had arrived.
The two of them sat down in the living room and began eating.
However, halfway through the meal, Souta suddenly realized something.
He had been too fixated on solving the problem within the Date A Live world.
Why limit myself to just this world?
Why not consider other anime universes?
After all, the multiverse was full of crazy, overpowered abilities.
There were plenty of ways to gain immortality in different anime worlds!
If he could obtain immortality, he could provide Kurumi with infinite time energy.
If Kurumi herself could gain immortality, the problem would be solved completely.
With this in mind, Souta immediately picked up his phone and asked:
"System, can I take Kurumi to other worlds?"
The system responded:
[Yes. There are two ways to travel:]
[1. If a friend invites you, you can travel to their world.]
[2. If you use a 'Travel Card' (one-time item), you can travel to a specified world, selecting an approximate time and location.]
"Wait, I can set the time and place with a Travel Card?"
Souta was shocked and quickly asked:
"Does that mean I could use a Travel Card to go 30 years before the start of Date A Live?"
[No. A friend's world is time-locked to sync with reality. You cannot time-travel within a friend's world.]
"Figures... No loopholes to exploit."
"Alright, then—do I have any Travel Cards?"
[No. Travel Cards must be purchased with points in the system's store. Points are earned by completing missions. The store and mission system will unlock once the system has at least three users.]
"Wait—points? Missions?"
This was the first time Souta had heard about this.
But the three-user requirement was annoying.
Right now, there were only two users—him and Kurumi.
Who knew how long it would take to get a third user?
"Is there any other way?" he asked, unwilling to give up.
[Yes. The system provides a 'Newbie Starter Pack' for the host. Would you like to claim it?]
"...Wait, I have a starter pack!?"
Souta was genuinely surprised—
But after thinking about it, he realized it made sense.
When he first found this strange phone, he had assumed it was some scammer's trap.
He hadn't bothered exploring its functions at all.
If he had checked earlier, he probably would have discovered this sooner.
Without hesitation, Souta claimed the Newbie Starter Pack.
A notification popped up:
"Finally, a Travel Card!"
This meant he could now solve Kurumi's time problem!
As for the other two items...
Souta asked, "Is the 'Invitation Letter' the same as the one Kurumi received—basically, a phone?"
[Correct. The system periodically distributes Invitation Letters at random. However, the one in your possession allows you to choose who to invite.]
"So I can choose...?"
This was a huge advantage!
The system did hand out invitations, but since it was random, Souta had no control over who received them.
However, the Invitation Letter in his possession allowed him to target a specific person.
Unlike Travel Cards, which were one-time use, the Invitation Letter created a permanent connection.
If someone accepted the invitation and later invited Souta in return, he would gain unlimited access to their world.
It would be just like how he could now freely enter and exit the Date A Live world.
The only difference was that—
If he traveled to Date A Live using this method, he would appear directly next to Kurumi.
But if Kurumi wasn't in Date A Live at the time, he would likely be randomly teleported somewhere.
