Hyperion, a mysterious ship that travels through the sea of quantum, spans time, travels through space, and sails through various worlds. Unknowingly, more and more people are on board...

Kiana: "Captain, why is there one more!"

Mei: "Captain, can you explain this new sister?"

Bronya: "You playboy, go to Siberia and dig potatoes!"

Jizi: "Captain, what's the situation with this person who looks so much like me?"

…

Captain (sweating): "Ahem, I just want to give you a warm home. Let's talk it over. Put down the Nameless Realm and the Clear and Condensed Realm in your hands first..."

"Little one, you've followed me all this way, and you're already so eager to become my disciple? You should know that I, the Palace Master, am usually very busy."

"But, I really want to become stronger, you big fox demon."

Looking at the child with white fox ears and tail in front of her, Yae no Miko smiled slightly. "Senior Fox Palace, you can't escape my grasp now."

"It's not impossible for me, Tsukasa, to teach you how to become stronger, but I don't want to be your master. The word 'master' makes me sound really old. From now on, you can call me Tsukasa-neechan."

"It's not impossible for me to teach you my skills, as long as you can persuade—no, convince—a shrine maiden to live at Narukami Shrine, and I'll teach you all my tricks."

Ling Shu traveled through time and space, bringing the 'Genshin System' with him to the labyrinthine city of Orario. "Can I summon weapons and characters I draw in real life?" That's great. But... "Why do I have to choose a villain family to join at the start?" That's a real problem. PS: This is a fanfiction.

Collapse. A catastrophe whose beginnings were unknown, whose end is unknown. It has imposed the harshest test on civilization and brought humanity the most heartbreaking despair. The humans of previous civilizations struggled, and thirteen fire-chasing heroes risked everything, swearing to fight the Collapse to the bitter end. Though the outcome was death and defeat, they bravely faced death without hesitation. Bang… the sound of a head hitting the ground was heard, and a girl with cat ears fell to the ground, clutching her head in pain. "Ah! It hurts, it hurts! There's definitely a bump on my head. It's a work injury. I'll definitely go get something for medical expenses later." Padofelice stood up, rubbed her head, and suddenly felt something was wrong. All around her was a blank white space, empty. The strange sight made her heart tremble. Damn it!

How about some fan service?" "I'll kill you, really." "Sigh! With you like this, it's difficult for me too. How am I supposed to recruit readers? To save the author from starvation, debut as a Heroic Spirit, Shiki!" "Hmph, you might as well starve to death. I think that's better." "Don't you know? Ryougi Shiki, the only thing she can do." "That is," [As long as it's alive, even if it's a god, I'll kill it for you to see.] Simple and powerless, please read. The story will get better and better.

(The introduction is short and weak, please move on to the main text.) Elemental (weak and powerless), Collapse (omnipotent) Genshin, Initiate... what? You said it was Collapse Iron, then it's fine. ......... It begins with me, ends with me, my name: Beginning • End, Herrscher of the End. Walter: "Why is this Kaituo getting more and more collapsed?" Jizi: "You mean End? Although she looks as lively as Little Sanyue, I see loneliness in her..." Dan Heng: "She seems particularly concerned about my tail..." Silver Wolf: "She's always playing games, and the problem is, I can't even beat her. It's hilarious, that's why I didn't cry and make a fuss." Seele: "Give Bronya back to me!" Fu Xuan: "End! You scoundrel!" (Why do birds fly? When the meteorite of the End falls from the Cretaceous...)

They say dragon slayers become dragons themselves, but I, a lolicon, became a loli myself?! I used to be a lolicon-obsessed otaku. I was killed by a meteor shower and reincarnated as a silver-haired, red-eyed loli princess. How could I possibly give in?! But then that busty goddess said she could grant me three wishes. Such a good thing?! It must be a noble birth of wealth and honor, eternal youth and beauty, plus powerful magic. But after I made my wishes, I suddenly realized! I forgot to ask for that one thing! But I'm not going to sit around waiting to be ruined. Even if I'm a loli, I'll build a harem of beautiful girls! And so began my wonderful♂ life as a mischievous demon king~~~

Mash: Senpai, it's just the two of us left in Chaldea... Artoria: There's delicious food here every day, I don't want to go back to Chaldea!!! Dragon Girl: Master, these are my concert tickets, first row! Captain: One Piece, I'm taking them! Osakabehime: Waaaaah~ Gabriel, I can't spend money anymore, Master took my wallet... Arong: Hehehe, Tyr, what do you think of this drawing? Nero: Bismarck, take this Golden Theater Cannon! Siegfried: I'm sorry, I'll compensate for the lost package, I'm really sorry... Karna: Master, excuse me, Arjuna and I have a fan meeting. Attila: It's all bad civilization!!!

Ji Ran traveled to the Collapse World. In this world, which was extremely hostile to men... well, humans, Ji Ran felt a little panicked. However, after obtaining the [Dungeon System], he felt that his survival might be somewhat guaranteed. However, there were two options for the dungeon. The first was to clear the dungeon alone. This was too difficult, so he skipped it. Even if one person buffed the player, he still had to skip it! The second option, while the system's buffs would be weakened, would randomly match players with other players. So... Kiana: [Huh? This world actually has so many fun things?] Alicia: [Hehehe, it seems I'm popular elsewhere, too?] Bronya: [Is this a new game? Okay, Bronya accepts the challenge! Watch Bronya clear it with one life!] Raiden Mei: [I'd like to ask, this dungeon allows me to become stronger and control the power of the Herrscher Core by increasing my natural strength, right?] Mei Raiden: [What the hell is this Shenzhou home cooking 300-style dish? (╯‵□′)╯︵┻━┻]
