A brilliant meteor streaked across the boundless blue sky of Teyvat, tracing a sharp diagonal arc before plunging toward the sea.
Boom!
The impact sent waves surging across the ocean, before the waters gradually calmed again.
Then—suddenly—a figure burst out from the spot where the meteor had fallen.
He looked terrified and breathless, gasping for air, his soaked body trembling with exhaustion.
After flailing for a moment like a drenched seabird, the man forced himself to focus. He scanned the endless expanse around him and spotted a distant coastline. Gritting his teeth, he began to swim toward it with all the strength he had left.
At last, he dragged himself ashore, coughing and gasping, half-drowned but alive.
That miserable, half-conscious figure was—
A human.
A fair-skinned, surprisingly handsome man.
[Congratulations, Host. You have officially set foot upon the continent of Teyvat. The Diary System is now active and at your service.]
A gentle female voice echoed inside his mind. Startled, the man froze mid-breath before speaking cautiously.
"System? Teyvat? Wait—did I just… time-travel?"
Then, after a short pause—
"Damn it! I was living perfectly fine in my own world—got a promotion, a raise—and now you've actually teleported me across dimensions?!"
He sighed sharply. "Thanks a lot… really, thank you so much! Damn it all—"
After venting his frustration with colorful vocabulary, the man gradually calmed down. Feeling his wet clothes cling uncomfortably to his skin, he asked in a steadier tone:
"Alright, System. What exactly are your functions?"
[Host, I am the Diary System. By writing a diary entry each day, you can perform a check-in and receive random rewards.]
[Rewards are drawn from across all known—and unknown—realities.]
"Oh, I see." Vaen rubbed his chin, thinking. "And what if my luck's terrible and I can't get anything useful?"
[Each check-in also grants you points, which can be spent in the System Mall.]
"Hmm. That's fair enough." He nodded thoughtfully. "But why a diary? Every other sign-in system I've ever heard of just asks for a daily login."
[That's… part of my factory settings, Host. I'm afraid I can't alter it.]
[Don't worry—just five hundred words a day will do.]
"Only five hundred? Not bad." Vaen considered that manageable. "And how do I even write it? I don't exactly have paper lying around."
[Simply narrate your thoughts silently in your mind, and confirm when you're ready. The entry will be recorded automatically.]
"Alright…" Vaen nodded slowly.
Of course, he already had his suspicions. If this system worked anything like those in the novels he'd read, then his diary entries wouldn't stay private. In those stories, someone always ended up reading them—usually the characters from the world itself.
In other words, the Diary System was probably broadcasting his thoughts to the people of Teyvat.
Typical.
"And judging by how clunky this thing sounds," he muttered, "I must've gotten the beginner's edition."
Still, he decided to test it. "Hey, System, do you have a novice gift pack?"
[Technically, no. But considering the… unpleasant nature of your arrival, I'll grant you a personal compensation package.]
"Now we're talking. Open it."
[Congratulations, Host. Rewards as follows:]
• Ten additional sign-in opportunities
• Advanced Anemo Affinity
• 500 Check-in Points
• Basic Pyro Affinity
• Ink-blue Mondstadt Attire
• Comfortable Underwear ×3
• Moderate Anemo Control
• Advanced Pyro Control
• Self-heating Hotpot ×5
• 499 Check-in Points
• Moderate Geo Control
"…Not bad," Vaen muttered. "At least you didn't dump a bunch of women's clothing on me like those poor guys in the novels."
Still, he frowned. "Wait—Geo control? I didn't even sign for that!"
Seeing no one around, Vaen sighed and quietly removed his soaked clothes.
But just beyond his perception, a gentle breeze swirled through the air—vaguely taking on the shape of a person.
"Oh my," came a soft, teasing voice. "How indecent. The world truly has gone astray."
The wind spirit half-covered its eyes in mock modesty, though its fingers peeked apart mischievously.
"Tsk tsk… that's quite the physique."
"Hmm?" The breeze blinked in surprise when Vaen pulled out a pair of underwear decorated with triangle patterns—only to see them appear square a moment later.
"Did I just—see that wrong?" the wind murmured in confusion.
Meanwhile, Vaen slipped on his new clothes, muttering curses at the System.
"…Okay, fine. I admit it. They're actually comfortable."
Once dressed in his ink-blue Mondstadt outfit, Vaen sighed with relief.
After one last glance around, he began walking inland.
The breeze watched him disappear into the distance, its voice carrying a playful note.
"Interesting."
Moments later, the wind condensed into the form of a slender, youthful bard—bright eyes, carefree smile, lyre in hand.
Anyone familiar with Teyvat would recognize him instantly:
Barbatos, the Anemo Archon of Mondstadt—known to mortals as Venti, the wandering bard.
[Diary Entry #1 – Vaen Corith]
Today, I saved a little girl who nearly got hit by a truck. In doing so, I got hit myself.
As I was flying through the air, I realized something strange—no normal collision should've launched me this far. Why was I still falling?
Sparks ignited around my body.
Before I could process what was happening, I turned into a meteor and crash-landed into Teyvat's ocean.
0/10 for landing.
Thankfully, aside from the pain, I wasn't seriously injured.
I suppose, as far as transmigrations go, this one could be worse…
Damn, it hurts. Bad review.
Alright, time to adapt. If my guess is right, I've landed somewhere near Mondstadt—the City of Freedom, where my favorite stories began. It's safe, peaceful, and friendly to newcomers like me… hopefully.
For now, I can only rely on this diary. Please, System, don't let me down.
Vaen looked at the floating holographic journal before him with satisfaction. Its title read:
"Vaen Corith's Journey Through Teyvat."
He looked around—and immediately realized he was lost.
"Grass…" he muttered under his breath.
Just as Vaen predicted, the Diary System began transmitting his entries to various key figures across Teyvat.
And when the women of this world read his words—his fall from the heavens, his strange power, his awareness of their stories—they were shocked.
Some felt curiosity.
Some felt unease.
And others… suspicion.
