Story begins:
"Hello there. My name is Sumai Kagami. I'm currently the CEO of **** at just the age of 24. Not bad for an otaku, right? On top of that, I'm already married with two kids, though they're still infants."
I had taken a day off work, not knowing it would be my last day alive. One moment I was sleeping peacefully, the next I woke up… standing in front of a truck.
Well, not the legendary Truck-kun, but something smaller.
'Tsk, I might not be as big as Truck-kun, but show some respect.'
I froze. 'Did the truck just talk? Wait—ROB can read minds?'
"Of course I can. Now then, why don't we start with your second question?"
'His voice is surprisingly playful for someone who holds the power of reincarnation, but… I guess I'll listen.'
"Did you forget? I can read minds."
"Tsk."
"Back to your question. You died because you were sleepwalking and slipped… right into a toy truck."
'…So I was killed by a toy?'
He nodded.
'And now that same toy truck is going to reincarnate me?'
"Don't be so disrespectful. I'm not just a toy. I am the one who will inherit Truck-sama's mantle in a few decades. Since you died by me, I have the right to reincarnate you, even if I lack experience. It's the rule. And with that, your two questions are answered."
'Wow. I'm actually about to be reincarnated. What should I even wish for? Though… I'm sad about leaving my kids behind.'
"Cough, cough."
'Ah. Right. He can read minds.'
"Normally, you'd get three wishes. But since you're the first person I'm reincarnating, you get nine. However, because you've been disrespectful, you'll only get seven."
'And I forgot one of the golden rules of reincarnation: never make ROB angry.'
"Do I at least get my appearance and the world choice for free?"
"Only appearance. If you want someone's looks along with their powers or talents, it costs a wish."
"Hmm… fine. My first wish is to reincarnate as a Manas Divine Wisdom Core, like Ciel from Tensura."
"That will cost you two wishes."
"What?! How?"
"One for the species, another for the world."
"Tsk. Then my third wish is to have the appearance of Seijuro Akashi from Kuroko's Basketball. I also want the Generation of Miracles' skills, excluding Kise's. But instead, I want Kise's copying ability as a passive trait—not an active skill. It should surpass Perfect Copy in its normal state, and even be stronger than Perfect Copy combined with the Zone."
"…Wow. You actually thought this through. Even I'm surprised." The truck paused, as if communicating with someone unseen. "Alright, granted."
"My fourth wish is to reincarnate inside Veldora's cave three days before Rimuru meets him."
"Easy enough."
"For my fifth wish, I want the Akashic Record: Lord of Information."
"No. But when you evolve into a true Divine Manas Core, you can gain Lord of Information: Akashic. For now, you can only have 'Records.'"
'Sigh. Fine. But why can't I be reborn as a Divine Manas Core right away?'
"You don't have enough magicalules, souls, or even a name. For now, you can only reincarnate as a pseudo-Manas Core. Once you acquire those things, you'll evolve into a true one. That said, you should be able to fight all Demon Lords except Guy—because of Suspended World—and Milim—because of Stampede."
'…Sigh. My sixth wish is for a multiverse system.'
The truck crossed its nonexistent arms. "Since you're my first candidate, I'll give you a system that lets you travel to a maximum of twenty worlds. Tensura and your original world won't count toward the slots, so you'll actually have twenty-two. Each time, you'll be randomly reincarnated or transmigrated. But the worlds are permanent—you can't swap them out unless you use your final wish for a two-sided deal."
'Hmm. A two-sided wish… got it.'
"For my last wish: before entering any new world, I want to come here first. If one of my past two lives was interesting, I want to be able to change that timeline however I want before I reincarnate into it. And since this wish is kind of a 'half,' I want no additional characters other than those from the canon."
"Tricky human. But just because canon characters are the only ones appearing doesn't mean there can't be strong characters who existed off-screen. Not everyone with potential was scouted in the story, after all."
'That makes sense.'
"Good. Then it's granted. Now enjoy your new life. Don't die too quickly… and make sure to entertain me. Goodbye."
'He really sounds like a final boss.'
"You'll meet me here again in your next reincarnation."
'Ah—forgot he can still read my mind.'
"And check the gift I left for you."
"…Thanks."
