Fifth Tier, in the chat group's power evaluation, represents at minimum planet-destroying level.
The "planet" here refers to Earth-standard sized planets—satellites like the moon don't count.
As for the higher Sixth Tier, it requires at least galaxy-destroying capability.
Worth noting, the galaxy mentioned here uses the Milky Way as standard reference—meaning a galactic structure with at least several hundred billion stars and a diameter exceeding 100,000 light-years.
This means powers capable of destroying simple stellar systems like the solar system, or ordinary constellation structures like Orion or Perseus, despite requiring energy trillions of times greater than destroying Earth, still fall within Fifth Tier boundaries.
The difference between Fifth Tier's upper and lower limits is even greater than the gap from First Tier to Fifth Tier combined.
Tohsaka Rin didn't know which level Ryuga belonged to, nor when he had reached Fifth Tier.
In any case, when she checked, Ryuga had already advanced.
She believed that with Ryuga's previously demonstrated ability to easily challenge higher tiers, even if advancing to higher levels became difficult in Fifth Tier, he definitely wouldn't be weak.
She had expected this explosive news to cause everyone's amazement.
But unexpectedly, everyone's reactions were remarkably consistent.
[Erica: "Oh."]
[Kanae: "Oh."]
[Madoka: "Oh."]
[Jibril: "Oh."]
Seeing this reaction, Tohsaka Rin's eyes widened.
[Tohsaka Rin: "???"]
[Tohsaka Rin: "Aren't you surprised? This is Fifth Tier! Power that can easily destroy planets and worlds!"]
In her understanding, this had already surpassed the limits gods could reach.
Even the legendary Counter Force would at most be this level, right?
Faced with this level of power, these people's reactions were so bland?
Regarding Tohsaka Rin's surprise, Erica was somewhat puzzled.
[Erica: "At this point, would you still be surprised by Ryuga-sama getting stronger?"]
The twin-tailed young girl was slightly stunned.
[Tohsaka Rin: "Uh, seems like I really wouldn't be."]
[Tohsaka Rin: "But this is Fifth Tier! Planet-destroying power!"]
[Kanae: "Whether Fourth Tier or Fifth Tier, they're both far beyond my understanding. Feels about the same."]
[Madoka: "+1"]
For two people who hadn't even seen First Tier strength beings in person, they'd lost any sense of scale from Third Tier onward.
[Tohsaka Rin: "...You're right too!"]
The twin-tailed young girl had originally wanted to say more, but after thinking for two seconds, she was convinced.
At this point, forget Fifth Tier—even if Ryuga jumped straight to Sixth Tier, she'd at most exclaim once and wouldn't find it impossible.
Their worldview had long since been molded into Ryuga's shape.
[Tohsaka Rin: "So what exactly is Ryuga-sama doing now?"]
After going in circles, the topic returned to the starting point.
[Erica: "Previously, he was unifying the Divine Realm. Now he's not in my world anymore—should be at the new member's place."]
[Tohsaka Rin: "Unifying the Divine Realm? I feel like you casually mentioned something incredible. But Ryuga-sama is now at the new member's world? Feels like even big shots have it tough!"]
[Tohsaka Rin: "@Jibril, stop lurking. Got any information to share?"]
Noticing Jibril was watching, Tohsaka Rin immediately asked this new member for intel.
Hearing Tohsaka Rin's inquiry, watching Ryuga surrounded by Fanlou, Hubie, Azril and others, Jibril chuckled and immediately replied.
[Welcome new group member to the chat group]
[Jibril: "Ryuga-sama isn't doing much right now—just touring around our place, enjoying beautiful scenery, and solving some small troubles."]
[March 7th: "Touring? Scenery? Where? Is it pretty?"]
[Tohsaka Rin: "What small troubles? I feel like the more casual the tone, the more incredible it'll be behind the scenes..."]
[Tohsaka Rin: "Wait! Who?"]
[Jibril: "New member!"]
[Erica: "New member!"]
[Kanae: "New member!"]
[Madoka: "New member!"]
[Tohsaka Rin: "No copying!"]
[Tohsaka Rin: "The new member came at such perfect timing! March 7th—that name sounds so unique. Are you a girl?"]
A new member suddenly barging in surprised everyone.
And judging by appearance, this new member had quite a special personality.
Should I call it overly familiar, or lacking a few screws... Would a normal person's first concern upon encountering an interdimensional chat group be tourism and scenery?
Somehow, this new member named March 7th left Tohsaka Rin with an impression of unreliability.
Meanwhile, elsewhere.
In the Honkai: Star Rail world, within the vast universe, inside the Astral Express, in March 7th's room.
March 7th—a girl with pink hair, kaleidoscopic pupils like tangled fate, a curvaceous figure who looked very lively and cute—had no idea she'd been underestimated.
Hearing Tohsaka Rin's question, she immediately replied excitedly.
[March 7th: "That's right! How did you know I'm a super duper cute girl?"]
[March 7th: "Wait, where is this? Who are you people?!"]
[Madoka: "?"]
[Erica: "Only now asking this?"]
[Tohsaka Rin: "Don't tell me you only just realized something was wrong? I thought you were the overly familiar type, but turns out you're the slow, natural airhead type?"]
The twin-tailed young girl began furiously complaining.
You've been chatting with the group in your head for so long and only now notice something's off?
Hearing Tohsaka Rin's sharp-tongued complaints, March 7th puffed out her cheeks in the Astral Express cabin.
[March 7th: "Who's the slow natural airhead! I can't really understand what you said, but I definitely feel like you're calling me stupid!"]
Guess airheads have sharp instincts about this kind of thing?
At least March 7th's intuition wasn't wrong.
[Tohsaka Rin: "I didn't mean that—you're imagining things."]
[March 7th: "Really?"]
The pink-haired girl widened her eyes and actually believed it.
"Definitely an airhead."
Seeing the girl's reply, the twin-tailed young girl shook her head and made this judgment.
But naturally she wouldn't say it out loud.
[Tohsaka Rin: "Of course it's true!"]
[Tohsaka Rin: "Anyway, welcome, new member! Want us to explain this chat group's functions and situation?"]
[March 7th: "Oh right! I still don't know what this place is. Could it be connected to our Astral Express network by some former Nameless?"]
The Honkai: Star Rail world is a sci-fi future where interstellar travel has become common transportation.
Here, even the Astral Express jumping between star systems is networked and can achieve real-time communication with the outside world.
In this world, various power systems exist. If former Astral Express passengers—Nameless—could remember the Express's port address, they could potentially communicate with the train crew.
Against this background, March 7th naturally wouldn't be as shocked by the chat group's existence as Kanae had been previously.
She'd at most consider it some advanced technology.
[Tohsaka Rin: "Nameless?"]
[March 7th: "Adventurers who explore the stars like our Astral Express! I remember Himeko-neesan saying we're quite famous—surely you've heard of us?"]
The pink-haired girl found this strange.
Although she'd visited places that didn't know about the Nameless before, those were usually indigenous planets that hadn't even achieved interstellar society awareness.
But now, since these people could master interstellar communication technology, they should understand interstellar society.
Anyone familiar with interstellar society shouldn't be unaware of the Trailblaze faction's Nameless!
Although their strength wasn't particularly great, their reputation in this galaxy was definitely top-tier!
Honestly, March 7th was a bit disappointed.
She'd been hoping to show off a bit!
Naturally, the chat group members couldn't give any other response.
[Tohsaka Rin: "Sorry, never heard of it."]
[Madoka: "I feel like March 7th-neesan might have misunderstood something?"]
[Erica: "Rin, did you notice the new member just mentioned interstellar exploration?"]
[Tohsaka Rin: "!"]
[Madoka: "!"]
Those who understood this term's weight were immediately stunned.
If the new member wasn't lying, this time the new member's world was very likely the most technologically advanced world yet.
Regarding everyone's reaction, March 7th felt puzzled again.
[March 7th: "Interstellar exploration—what's wrong with that?"]
[Tohsaka Rin: "Mind if I ask where you are right now?"]
[March 7th: "My room!"]
[Tohsaka Rin: "..."]
[Tohsaka Rin: "I mean your specific location. Are you on Earth?"]
The twin-tailed young girl nearly coughed up blood. Who knows where your room is?
Hearing this, March 7th finally understood what she meant.
[March 7th: "Oh! You mean this. I'm currently on the Astral Express... specific coordinates unclear, but we're about to reach the Herta Space Station. Himeko-neesan said we need to resupply there."]
[March 7th: "As for the Earth you mentioned, I don't know which planet that is. I'll check the database later. But according to Uncle Yang, the Herta Space Station orbits the Azure Planet, so it's probably not the Earth you mentioned."]
[March 7th: "However, if you have interstellar coordinates, you can send them to me. Anywhere with coordinates, our Astral Express can reach—we could visit you!"]
The unsuspecting girl said this enthusiastically.
Without any scheming nature, she didn't realize she'd already leaked most of her intelligence.
Naturally, she couldn't realize how dumbfounded the recipients of this information were.
Hearing these beyond-common-sense words, Tohsaka Rin and Erica initially suspected the new member was a fraud playing with them.
But recalling March 7th's displayed intelligence, she didn't seem like the type who'd be good at deception.
But if what she said was true, wouldn't that mean the new member's world was truly incredible?
No wonder she didn't find direct brain-connection chat groups strange.
In her world, brain-domain internal communication devices had probably already become widespread!
Realizing this, Tohsaka Rin immediately replied:
[Tohsaka Rin: "March 7th-san, you seem to misunderstand our chat group. That's why you think we're in the same world, the same universe."]
[Tohsaka Rin: "I must tell you that we each come from completely different universes, completely different worlds."]
[Tohsaka Rin: "Rather than aliens, we're more like people from other dimensions."]
Seeing Tohsaka Rin's reply, the pink-haired girl was immediately stunned.
[March 7th: "Huh?"]
To be continued…
