After Kurumi left, Souta immediately began researching candidates for the Friend Invitation.
He needed to invite someone powerful, but not too powerful—someone with a strong sense of justice, good communication skills, and most importantly:
✔ Someone who wouldn't wreck the world for fun after the mission.
✔ Someone who could neutralize spacequakes.
For the spacequake problem, Souta had an idea—counteracting spacequakes with space itself!
According to Date A Live, spacequakes of the same magnitude can cancel each other out.
For example, Kotori Itsuka had once used a spacequake to counteract one caused by Kurumi.
Of course, trying to gather all ten Spirits to negate the Eurasian Sky Disaster was pointless—even all ten combined couldn't handle Mio Takamiya's pinky finger.
So, external power was a must!
Souta pulled out his iPhone and searched:
"Anime characters with spatial abilities."
It wasn't that he didn't know who had spatial abilities—
He just had too much information in his head and needed a refresher.
As the search results loaded, Souta skimmed the screen:
Kakashi Hatake – Uses the space-time jutsu Kamui to send objects to another dimension.
"Naruto's legendary '50/50' ninja... Sending things to another dimension won't stop a spacequake."
Shirai Kuroko – Ability: Teleportation.
"Misaka Mikoto's #1 fangirl... Her power's useless here. Also, the Toaru world is risky. Pass."
Sirin, Herrscher of the Void – Controls Imaginary Space.
"From Honkai Impact... She has a skill called 'Spacetime Tremor,' which is similar to spacequakes. Theoretically, she could counteract them."
But... could she really negate an 800-kilometer-wide spacequake?
Souta fell into deep thought.
Sirin was strong—she had wiped Siberia off the map, after all.
But destructive power didn't always mean rescue capability.
And more importantly—would she even want to help?
"Let's keep looking..."
Natsuki Minamiya – Uses Spatial Control Magic.
"Oh? The legal loli from Strike the Blood? But she's too weak..."
Maxwell(Demon) – Controls Thermal Boundary Gates for teleportation.
"That crazy pervert from Mondaiji? Actually, in the Little Garden world, anyone who controls 'boundaries' can use Spatial Gates..."
He had just realized the perfect choice.
The Little Garden (箱庭)
The world of Mondaiji Are Coming from Another World, Aren't They?—
A third-person omniscient universe created by the gods.
A mix of all mythologies into a single shared world.
And within this world of war gods and celestial beings, three races reigned supreme:
✔ Pure-blooded Dragons
If Born Gods were the strongest in concept manipulation,
Then Star Spirits were the strongest in spacetime control.
To them, manipulating spacetime was like breathing.
However, since Mondaiji never focused on spatial abilities, Souta hadn't thought of them at first.
Candidate Selected: White Night Demon(Shiroyasha)
Several Star Spirits appeared in Mondaiji:
✔ ShiroYoruMaou (White Night Demon)
✔ Halloween Queen (万圣节女王)
Among them, White Night Demon was the best choice.
✔ She had a strong moral compass—she protected the declining Arcadia community.
✔ She was friendly—she could joke around with Izayoi and the others.
✔ She was no longer violent—her past as a Demon Lord was long over.
Convincing her to save 150 million lives shouldn't be too hard, right?
Souta made up his mind.
White Night Demon was the one!
However, he couldn't invite her just yet.
He had to be careful about one thing:
He needed to invite her before she regained her full divine power.
Divine Restrictions in Little Garden
In Mondaiji, gods couldn't just enter the lower world freely.
If three Born Gods set foot on Earth, their divine presence alone would:
💥 Set the sky on fire
And White Night Demon?
📌 As a "Full Authority" Divine Entity, her true form was far too powerful for any normal world to withstand.
However, in the early story, her divinity was sealed.
📌 At this stage, her strength was much lower—around a "Four-Digit" level.
✔ Strong, but not overpowered.
✔ Could still get work done.
✔ Had responsibilities in Little Garden, so she wouldn't stay in another world too long.
"She checks all the boxes!"
Now, he just had one last question:
"Can I specify a character's timeline when using the invitation?"
Souta double-checked White Night King's background online.
Then, after making sure he had all the details, he took a deep breath.
"Alright... Let's do this."
"Use Friend Invitation—invite White Night Demon(during her 'Floor Master' period) from Little Garden."
💡 [6th Friend Invitation Sent!]
As soon as the system notification popped up, Souta's heart pounded.
He couldn't help but feel nervous.
After all... he had just invited someone who could obliterate every member of the chat with a snap.
