I'm in the Honkai world, having just traveled through time. The question is, what's with this strange narration? [Take off! Take off! Such a wonderful start! Looking at this opening, you feel like your life is about to reach its peak.] No, it doesn't feel like it's taking off at all. Besides, the Honkai world is notoriously unfriendly to ordinary people, right? (╯‵□′)╯︵┻━┻. [There are many beautiful Valkyries to choose from.] [Even if you want to go big, there are Honkai Gods, Soulsteel Mini-Bishops, and Cyborgs as well.] [You feel like you're already fired up!] Not at all... Wait, Otto, you can do that? [Changkong City! The place where destiny begins! This is the perfect place for you to take your first step after traveling through time!] [Defeat the Herrscher of Thunder, then collect the Herrscher of Void and the future Herrscher of Reason into your crystal palace—the world is mine!] Wow, with this setup, you want me to go head-to-head with the Herrscher? I get it. You probably want me dead.

Lin Yu, an ordinary delivery man, lives in a world without collapse. Kiana, Mei Raiden, and Bronya are still at Chiba Academy, facing the college entrance examination and preparing to enter St. Freya Academy.

Aponia, a doctor in charge of the psychological counseling room, is also a resident of the Golden Courtyard.

The ordinary delivery man had no connection with these people.

But a special order changed everything.

[Sent to the rooftop to the white-haired, blue-eyed idiot, and told her to eat well, as she always forgets to bring her meal card - Raiden Mei]

Heavy rain in a cloudless sky and biting cold wind in the hot summer.

The dilapidated teaching building, the purple-striped vines inside, the white-haired girl who appeared once and then disappeared, and the numerous corpses on the empty rooftop...

The insulated box that was broken and then restored, the electric car's power disappearing out of thin air, the constantly changing order information, the raincoats and clothes that remained dry even after the heavy rain, the purple rainbow seen during psychological counseling...

The smell of gunpowder from cooking, the half-filled meal card and purple crystal foam from the automatic flushing toilet...

Numerous signs continued to destroy Lin Yu's consciousness.

When he entered the dream and opened his eyes again, he found himself in an unfamiliar place, and all he saw was a white-haired girl being hit by the waves.

Kiana Kaslana...

And he also came into contact with the concept called collapse.

…

"Kiana, I like you, so I can't watch you die in front of me!"

…

The pink crystal flower shattered and reassembled.

…

"Allysia, you are the biggest idiot. Why...can't you just trust me for once?"

…

"Xi'er, you must learn to be strong and protect yourself!"

Mo Yi, who came to the Honkai World, relied on the Honkai Game Console to obtain various invincible Stigmata - Toilet War God Hisoka, Crimson King Qi Qi, Magic Cat Kyubey...

He was preparing to marry Binglu Anna and live a peaceful life, but he gradually discovered that the plots of the games he played seemed to be true?

"The Rising of the Goose Brave"

Mo Yi: When the sun sets, it will be my death. Before that, I will let you see what an arrow that shatters the stars is!

Bianca: Stop, this is my theater version!

"Magical Girl Gracie"

Gracie: For those of you who have had hope so far, I don’t want them to cry. I hope they can smile until the end. It's up to me to break the rules that stand in the way of this, to change them - that's my wish. Please make it happen, Kyubey!

Chubby Yi: I understand all the principles of saving the world, but how do you want me to endure all this? If saving you is a sin, let me be the sinner.

"Miss Alicia, who is good at teasing people, wants me to confess my feelings ~ Miss Pink Fairy, who is unpredictable, is not only cute"

Alicia: Alicia has always loved everyone, but I also want to try the feeling of being loved once in a while~
