Asakusa Tōru, male, sixteen years old, is a transmigrator.
Perhaps it was because he had devoured countless books in his previous life that he was able to be reborn into this mishmash, all-in-one crossover anime world.
Unfortunately, even after changing worlds, he was still an orphan.
Fortunately, having no parents wasn't necessarily a bad thing.
As long as you didn't have parents, you were basically invincible on the internet—immune to any threats involving "your parents."
Standing tall and upright, head held high, when someone sneered, "Your mom's dead," you could cleanly and decisively nod and reply, "Yeah, my mom is dead," leaving the other party replaying the moment afterward, wishing they could slap themselves dozens of times while cursing themselves for being absolute trash.
This was known as the Invincible Golden Body.
That said, even for a transmigrator, having no parents was indeed difficult. If not for the fact that he had already been sent to an orphanage by the time his past-life memories awakened, Asakusa Tōru seriously suspected that with a bit of bad luck, he might have died in some back alley before he ever recalled his previous life.
But the past was the past.
Relying on his awakened memories, he struggled and worked his way to the present. Just when he thought that in this lifetime he might only ever get by with a small "foresight buff," his long-overdue golden finger finally arrived—sixteen years late.
A diary.
Its full name was: "The Diary That Gives You Rewards as Long as You Casually Write in It."
A very simple and brutally straightforward name.
However, Asakusa Tōru—well-read as he was—was not about to be fooled so easily.
Almost the moment he obtained the diary, he recalled a whole pile of bizarre diary-stream novels from his previous life.
Stories where the protagonist wrote a diary while being tortured by the entire world, only for the diary to be exposed after death to clear their name, leaving everyone else drowning in regret—or stories where the diary was synchronously revealed, with the protagonist using their unhinged inner monologue written in the diary to "conquer" (or "strategize to overcome") various heroines like some kind of inner-voice protagonist.
Even now, thinking back on them made him want to complain: why on earth did those diary-stream protagonists genuinely believe that the diaries they wrote wouldn't be seen by anyone?
I mean—what kind of normal person writes a diary anyway?
Thankfully, the diary he obtained was not that sort of scammy garbage designed to screw over its host.
Instead, it was a proper, orthodox, officially registered, ace diary!
A clearly defined scoring algorithm for diary content.
A massive reward pool available for draws.
A clearly designated range of readers.
On the very day he received the diary, Asakusa Tōru abandoned his original plan of getting rich by copying light novels, and instead devoted himself wholeheartedly to developing his golden finger.
After some simple research, he picked up his pen and wrote the very diary entry that Sakayanagi Arisu had seen.
Messing around, spoiling, and then declaring war.
These three corresponded respectively to the diary's different evaluation mechanisms.
The level of entertainment in the content, the appropriateness of the spoilers, and the emotional fluctuations of the readers.
According to the diary's algorithm, the written content would be evaluated, a final score calculated, and rewards drawn.
It wasn't particularly complicated—at the very least, Asakusa Tōru could clearly understand what he needed to do.
Setting aside the score and rewards for the moment, although he had already completed today's entry, the diary's settlement still required a bit of time.
So his attention shifted to the designated reader range.
The reason he knew that the readers, like himself, were students of the Advanced Nurturing High School was not only because he had recently received his own admission notice from the school, but also because the diary itself had already made it explicit.
[Current storyline: Welcome to the Classroom of the Elite]
[Today's diary plot index: B]
The former was the limited scope of the diary copies distributed by the diary—only characters within the corresponding storyline had a chance to receive a diary.
The latter was a special bonus multiplier. When situated at a key plot point, this index would multiply the original evaluation score.
In other words, the more crucial the content, the more crucial the timing at which it should be written.
Taking this into account, and after recalling the plot of Classroom of the Elite, Asakusa Tōru ultimately decided to write that kind of content.
Leaving himself some room to maneuver—ensuring there were spoilers, but not too many—while also trying to provoke the readers.
He couldn't determine exactly who had received the diary, but by testing them one by one in sequence, someone was bound to reveal a flaw.
As long as he grasped their specific identities and slammed them with targeted spoilers, he refused to believe he wouldn't be able to force out some emotional fluctuations.
"Still… Advanced Nurturing High School, huh." Looking at the text following the current storyline on the diary page, Asakusa Tōru let out a faint sigh. "It really does feel… exactly as expected."
It had been mentioned before—this was a giant crossover world.
This world had the Shinomiya Group, the Kōenji Group, the Toyokawa Group, and the Suzuki Group. Aside from not seeing the Speedwagon Foundation, pretty much every major conglomerate that should exist seemed to be here.
Girl bands holding live performances everywhere, the once-in-a-century idol Hoshino Ai, a shut-in youth scared to death by a tractor.
Although there were no visible signs of the supernatural for the time being, characters from all sorts of works were present.
The reason Asakusa Tōru felt it was unsurprising was simple.
He had interacted with them.
Whether it was some emotionless "ultimate masterpiece," a sickly genius love-brained white-stocking loli, or an everyone-loves-him honest-to-a-fault voluptuous beauty—
He had interacted with them all.
Though he didn't know whether they remembered someone like him, the fact that he would enroll in Advanced Nurturing High School—and that his golden finger was even related to them—left Asakusa Tōru unexpectedly unsurprised.
"Hopefully this won't become a flaw that exposes my identity." He shook his head and stopped thinking further about it.
Things had already come this far. There was no way for him to go back and change the past. Thinking carefully, while keeping one's identity hidden was extremely important for diary-stream stories, as long as he remained cautious, even if his cover were to be blown, it would be a long time from now.
"What matters now…"
Was, of course, the settlement.
The first diary settlement.
[Today's entry completed. This entry's evaluation is 'A'. Drawing rewards.]
[Draw successful. Congratulations on obtaining the item 'Infinite Recorder'.]
Black-and-white text floated before his eyes, and a cold voice echoed in his ears at the same time. As the voice slowly faded, the text gradually vanished as well.
Immediately afterward, something fell out of thin air—
A recorder that looked utterly ordinary.
