I, the Rock King Emperor with 21 billion in power, have joined the chat group.

Masato (Yukino Yukinoshita): You might be okay, but what about your sister, your father, and your mother? Have you thought about that?

Sister must be killed!!! (Kyosuke Kousaka): Of course I've thought about it!! I'm not the chuunibyou I used to be anymore. I've long been mentally prepared and have a lot of backup plans for these dirty things that adults do.

Nana, who lacks abilities: Be careful, the government is not trustworthy. Especially the government of the Japanese archipelago.

Belle: Although I don't quite understand what everyone is talking about, I will support you in achieving your dreams. A man's dreams and aspirations are the most priceless treasures!

Accelerator: Hmph! Weak and feeble, nothing more than a world government. I've already destroyed at least two or three of them. If you really can't handle it, just summon me with a low-level mission card. I won't charge you extra points; I'll just make sure your world's Japanese government is completely subservient.

My sister must be killed!!! (Kyosuke Kousaka): Hey~~! Senpai Accord, I didn't have that idea.

Yuto Itsuji: That's really great. Everyone is still the same as before, as if no time has changed.

A Heartfelt Longing (Bell): Mr. Itadori!! I don't think I've ever spoken to Mr. Itadori. It seems you haven't chatted much since you got the chat group.

Yuuto Itsuki: Hahaha~~! I'm so sorry, I'm just too busy with real-life things, and I don't have much time to chat in the group. For the past few years, I've only used the group chat to check in, and haven't actually read the chat. Well, if my work gets a little easier in the future, I'll probably open the group chat more often.

Spider: Humans and spiders are completely different!! Spiders are chatterboxes; if they don't join a chat group at least twice a day, they'll probably get bored to death. But humans are different. Humans can chat with other people in the world, drink tea, and play games all night long. Wow~~~! I'm so envious, so envious! Spider, I'm so envious!

Wings Unfold (Sexy Prisoner): Spider-Girl has a charm that far surpasses others. Don't worry, girl, you're the best.

Spider: Ah! Thank you, thank you, Uncle! Speaking of which, I'm planning to kill an earth dragon soon, and I'm currently preparing. Please give me some energy!

Sister's ultimate attack!!! (Kyosuke Kousaka): Hmph~! A mere spider dares to use the strongest Spirit Bomb? However, seeing how hard you're trying, I'll share some of my Spirit Bomb with you...

Little sister is a killer!!! (Kyosuke Kousaka): Hey ya~~~!

Spider: Hey ya~~~! I've received your power, brother!

My sister must be killed!!! (Kyosuke Kousaka): Hmph~! Good brother.......

Before Kyosuke Takasaka could finish his telepathic message, a dazzling notification suddenly appeared at the bottom of the chat group.

It was written in large black characters above.

Chapter Two: The Theme of Newcomers and the Darkness of the Circle

I want to give Kobayashi ten eggs (Thor): Newbie!

Future Promising True Lord (Zhongli): Has a month already passed? Time really flies.

I'm Natsuki Subaru: Finally, some new people have arrived! Let's see who comes this time. I hope there will be some characters from the base world, preferably from a very later era. That way, we can have a clearer understanding of the fates of our group members.

Nana, who has no ability: Now is the time for me to step in again. As the strongest newcomer guide, I, Nana, will definitely give the new group members extraordinary care.

I am Subaru Natsuki: You're really reliable, Ms. Nana.

Nana, who lacks ability: I'm only reliable when I'm doing things like this, hahaha.

[Sizzle sizzle sizzle! Sizzle sizzle sizzle!]

[Locked...]

[Locked successfully...]

[Selecting new chat members now, which may take approximately 2000 standard time units.]

I am Subaru Natsuki: It's surprisingly subtle... Leisure, tragedy, racial apocalypse... How exactly are these three things connected?

Sister, you must kill me!!! (Kyosuke Kousaka): Indeed, I can imagine a tragic apocalypse, but a leisurely apocalypse... does such a thing really exist? If it's already the end of the world, why would there be such a thing as leisure?

Genuine (Yukino Yukinoshita): The criteria for choosing a chat option are indeed quite subtle, and I don't know how to put it.

The Promising Future True Lord (Zhongli): This kind of world, I think, is something I've never seen before. Leisure and apocalypse, such a world... um... no matter how I think about it, I just can't imagine it. According to general theory, even I can't imagine such an extraordinary world.

Ten Thousand Yen Shrine Maiden (Reimu Hakurei): Seriously, isn't Gensokyo just a world like this? How come you all overlooked that? [Reimu picking her nose image]

I am Natsuki Subaru: ? ? ? Ten thousand shrine maidens, don't talk nonsense. Although I grew up reading your doujinshi, how come I didn't know that Gensokyo was a leisurely post-apocalyptic world? I clearly heard you say that the humans in Gensokyo were super prosperous and developed... No... I think I understand now.

Ten Thousand Yen Shrine Maiden (Reimu Hakurei): Yes, for humans, it's incredibly advanced. But for youkai, it's not.

The 100,000 Yen Shrine Maiden (Reimu Hakurei): If it weren't for the purple-haired old woman and the first shrine maiden of the Hakurei Shrine creating this great barrier between fantasy and reality, those youkai who didn't earn human reverence would have disappeared long ago. [Image of Reimu lying down picking her nose]

The 100,000 Yen Shrine Maidens (Reimu Hakurei): These two old monsters should be swept into the dustbin of history. They really think they're so great, ruling Gensokyo? They leisurely want to hold banquets at my already impoverished shrine every day, forcing me to drink with them while I work overtime. If I weren't currently outmatched, I would have already picked up the Yin-Yang Jewel and smashed them both to pieces. [Image of Reimu lying on her side picking her nose]

The 100,000 Yuan Shrine Maiden (Reimu Hakurei): But don't rush, I've just accumulated 20,000 points, which is just enough to exchange for the ancient Chinese martial art I've been eyeing, [The Seven Great Hatreds of Devouring Heaven and Earth]. The name perfectly reflects my resentment towards those old women. Once I master this divine skill, I will surely blast these old relics to smithereens! Hehehehehehehehe

The future is promising, True Lord (Zhongli): @Ten Thousand Yuan Witch.

Ten Thousand Yen Shrine Maiden (Reimu Hakurei): ? Huh? What's wrong, Mr. Zhongli?

Promising Future True Lord (Zhongli): I think you'd better not practice it. The name of this kind of martial art... well, generally speaking, isn't very good.

Makoto (Yukino Yukinoshita): Hmm... I seem to have seen the name "Seven Great Hatreds" somewhere before... Hmm, wait a minute, let me search for it in the database on my computer.

Genuine (Yukino Yukinoshita): Hmm... Okay, found it. This entry... this wiki... seems a bit ominous. This ancient Chinese martial arts seems to be from a manga.

Ten Thousand Yen Shrine Maiden (Reimu Hakurei): Forget about manga or not, everyone in our group is a veteran. We've all read a lot of manga, and everyone's a character from manga, games, and novels. I, for one, often make cameo appearances in all sorts of doujinshi, and the worst part is, there are all sorts of doujinshi with stomach-pounding sex scenes that make my stomach hurt from reading them.

Masato (Yukino Yukinoshita): That's not what I meant. Well... how should I put it, I'll read you the contents of the "Seven Great Hatreds That Devour Heaven and Earth".

Genuine Item (Yukino Yukinoshita): [This is from ancient times, when Chi You witnessed the immense destructive power of natural disasters and calamities, which inspired him to create a world-shaking sword technique called "Seven Limits." His skill surpassed that of all the gods in the divine realm, making him invincible and the foremost god among martial arts masters.]

Genuine Item (Yukino Yukinoshita): [The Seven Limits of Devouring Heaven and Earth are divided into 'Heaven, Earth, Fire, Ice, Wind, Mountain, and Sea.' Each form possesses the boundless power of nature, its aura shaking the universe and dominating the heavens. When used in conjunction with the Tiger Soul, it is like a natural disaster descending, annihilating all life, and even gods and Buddhas are terrified!]

Ten Thousand Yuan Shrine Maiden (Reimu Hakurei): Isn't this incredibly powerful? Chi You! The ancient war god of China, he's an ancient god. Compared to such a figure, the purple old woman is at most just a tiny insect.

Genuine (Yukino Yukinoshita): .....Well, let me finish reading.

Genuine (Yukino Yukinoshita): [However, according to netizens' statistics, almost everyone who has learned the Seven Limits Sword Technique has met a bad end. Founder of the Seven Limits: Chi You. Fate: During his battle with the Yellow Emperor, he was devoured by the Tiger Soul, ultimately failing in his fight against the Yellow Emperor. Chi You's five servants: Each knew one move of the Seven Limits Sword Technique, for a total of the last five. Fate: Died mysteriously, their bodies mutilated. The Hungry Ghost: Knows all seven limits. Fate: His body was possessed by a demon. When the demon was destroyed, they were both annihilated...]

Genuine (Yukino Yukinoshita): There's a lot more after that, but I won't read it.

The Hundred Thousand Dollar Miko (Hakurei Reimu): .....

The Hundred Thousand Dollar Miko (Hakurei Reimu): .....

100,000 Yen Shrine Maiden (Reimu Hakurei): Luckily, I haven't spent my points yet. If I had, I'd be a complete sucker. This kind of evil martial arts has absolutely no compatibility with me, the unique character from Gensokyo who appears throughout the entire series.

Genji (Yukino Yukinoshita): Hey~! Reimu, you're really stubborn.

Masato (Yukino Yukinoshita): I.....

[Selection complete for this chat group's theme series: A Racial Apocalypse Intertwined with Leisure and Tragedy]

As a lucky bonus, members of this themed chat group will now receive an automatic self-introduction from the chat group system.

This time, the chat group connects to four worlds and unlocks four characters.

【Ta-da! The number one person!】

[A golden fairy in the sky, a leisurely yet tragic pioneer of the apocalypse, her beauty dancing in the heavens.]

Please make your voice heard.

Can you come and save the world? Join the chat group!

Can it save the world? Uh... it made a sound? What sound? Is that the new holy sword issued by the military? Or...? This is so strange. Why is this in my mind?

Can you save the world? (Muted for ten minutes)

[Ta-da! The first person has finished their self-introduction, now it's the second person's turn.]

A towering sky tower, a three-person motorcycle carrying the last two girls of the race, shrouded in mist under the setting sun, a world utterly deserted.

Please make your voice heard.

Chocolate and alcohol: I don't know what this sound is, but could you give me something to eat? Ah! I haven't found anything to eat properly for two days, I'm starving.

Chocolate and alcohol were banned for ten minutes.

[Ta-da! The second person has finished introducing themselves; now it's the third person's turn.]

[A world struggling to survive behind a colossal construct, a tale of hope and despair woven between the cursed children and the pure generation, a pity for no survivors, and the dark beast weeping within the heart of that young girl.]

Please make your voice heard.

Police officer: Although I don't know where this thing that suddenly appeared in front of me came from, I think we can have a good talk. Since you were able to implant this holographic chip in my mind without my knowledge, it must mean that you can kill me at will.

Police officer: Please tell me your purpose, otherwise, even if it costs me my life, I will immediately inform the Tokyo Residential Area Government of the presence of such a person.

Police officer silenced for ten minutes.

[Ta-da! The third person has finished their self-introduction. Although it was a bit long, it was still quite good. Now it's the fourth person's turn to appear.]

[The shadow of the witch that lingers throughout the world, a heart yearning for miracles, jealousy tearing half a ring apart, and pink protecting the figure behind.]
