Junxun is transported to another world with nothing.

However, after being bound to the Helpful System, he began a new life of rescuing dogs.

He initially thought it was just an ordinary, everyday world, helping people and doing good deeds. But it turns out it's not that simple. What's the meaning of this reward—the ability to see ghosts? And what is this multi-headed monster? Also, can't you girls at least give some reasonable reasons for asking for help?

Junxun said: "Don't keep bothering me. I'm just kind-hearted. Does helping others mean doing something in a certain way?"

My name is Yamabuki Huajin.

I’m done pretending—time to come clean. I’m a transmigrator, and yes, I have a system.

My ability? Every day I wake up randomly in someone else’s bed and transform into a different anime character.

Today, I opened my eyes to find myself in Academy City, with Misaka Mikoto pointing her Railgun straight at me.

Bros, what do I do? Waiting online, kinda urgent.

PS: Friendly reminder—please throw your brain away before reading this.

PPS: The lack of logic is the logic of this story.

PPPS: ...Brains all gone? Then come on in.

Transmigrating to a crossover anime world, Rosser finds himself a demon hunter, his landlord is Kayako, and his neighbor is Yotsuya Miko... Is Conan a mystery with an instant-death rule? Help! Where's the Counter Force? Where are the Heroic Spirits? Oh, they're just standing by and watching me die. What, I have a cheat code? But then again, you can only rely on yourself. I'm going to create... a new type of Moon! First, I'll transform into the Abyss Eye White Dragon, create a WarGreymon to give the world a little dragon-related shock, and you'll see, isn't that a dragon? Then I'll create a Five Holy Grail War world, making all the exaggerated descriptions come true, connecting it to the FGO world next door, shifting the blame, and whoever loses becomes a Lostbelt. Type-Moon people: Stop!! And then... Saber: You're Arthur too? What do you mean by "the strongest because the strongest is the strongest"? Goetia: Your Beast Law... wait, what the heck is the Law of Cycles? Gudako: Mashu, could it be that our world is the Lostbelt? Kazuma and Ayanokouji: Commander Rosser is my sun, ah, praise the sun. Poor Xiangzi: Mr. Rosser, a maid's duties don't include anything else~ Tokisaki Kurumi: You scumbag god, watch me exhaust you with my three thousand clones! Also known as "The Birth Diary of the Servant Universe" and "Slaanesh's Daily Life of Having Fun".

What would you like to do if you traveled to a daily anime? Harem? Plagiarism? After seeing the blank before the travel, the cute king, Sato Kazuma, and the shadow queen, Xia Jia had a bold idea. Since he could travel once, he could naturally travel a second time! He traveled again and came to the world of "Diqu".

"In a game-like world, it is only natural for me to invite players to come."

At this point, the fourth disaster came.

The [Silent Courtyard] whose bodies were healed by [Benefits]: Yuuki, Miyazono Kaoru, Sakura, Angel Beats!...

The second-year group with strong personal realities: Goko Ruri, Takanashi Rikka, Touma Sanae, Shadow...

The group that hopes to have a second life in the second world: Guitar Hero, Changing Doll, Iwanaga Kotoko, Kasumigaoka Utaha...

And, the reserve team for crossing into another world: Sato Kazuma, Blank, Moe King, Natsuki Subaru...

Xia Jia, who thought he would never return on the road to becoming a dog planner, suddenly knew that a gate to another world appeared in Akihabara, monsters in the real world were strangely revived, and superpowers and anime characters invaded reality.

The world of chaos is about to begin...

"The earth is in trouble, and the crossover has returned strongly! Save the world! Otaku!"

Xia Jia: "Recast the glory of the Astralia family, starting with me!"

Awakening from a dream, traveling to the pre-collapse civilization, you start out like a monkey trapped under the ruins and unable to move? Without relying on the system, you are ranked among the fire-chasing heroes, the inscription of [Divine Shadow]!

Kevin: "Regardless of the ideals of all living beings, regardless of the survival of civilization, this time, I must save him!"

Alicia: "This time... I must convey my feelings to him, and will not... let him leave me again."

Abonya: "Fate has made him fall into the nightmare of eternal calamity alone in the future. This time, I will not let him repeat the same mistake."

...

Zhu Yufeng: "This time, I will not let the pain of the past happen again. Even if I walk alone in the long night, I will fulfill my promise to her! Humanity will definitely defeat the collapse!"

This is a story about a boy who has nothing and becomes a savior hero, and it is also the story of all the heroes saving this lonely traveler.

[Characters appearing include characters from Honkai Impact 3rd, Star Iron, Grand Blue, Oregairu, Kaguya-sama: Love Is War, and Saekano... as well as some heroines whose origins are unclear. I won't cite their sources; those who like these series will understand.]

Don't worry, it's not some cuckolded turtle.

I transmigrated and gained the power of a Stand, thinking it would be the unfolding of a shonen manga, but why is this world so peaceful?! Why am I, who's supposed to be feared by all four of them, living a peaceful life as a high school student?! Yukinoshita, don't think I really won't hit you! Kasumigaoka, can you please stop fantasizing about me being the male lead in your novel?! Shinomiya, I won't confess to you, give up! Waaah, Megumi is so much better, I need some comfort~

This book is also known as "I Do Whatever I Want in the Honkai World," "The Herrscher of the End Wants Me to Build a Harem," "Honkai Simulator? I'll Go For Real," "Challenging Seven Valkyries in One Night," and "Durandal in Training." As a white-collar worker, without shaving, I came home from get off work to find a beautiful girl I'd picked up. It turned out to be Kiana, my wife whom I'd watched grow up?! After living with her for a while, I was transported to the Honkai world after the main storyline ended. Surrounded by Herrschers and S-rank Valkyries, my work turned into spending every day with my wife?! And what's even more outrageous is that they, whom I have a lot of affection for, actually want to help me grow my harem?! Every morning I wake up to see Mei on my left, Yuexia on my right, Airi at my left foot, Rita at my right foot, and a big duck in my arms! Then I try every possible way to "act unreasonably," but they all willingly satisfy my unreasonable demands. Even if I said Mei was bouncy in front of Kiana, let Bronya answer the phone while I was on a date with Seele, and even made Ellie only watch me and Eden...

[Collapsed Universe + Parallel Dimensions + Making Up for Regrets + Focusing on the Main Character + Multiple Female Leads]

Having unexpectedly traveled to a collapsing universe, Ye Li is determined to transform this imperfect world into the one he desires.

In the end, he sacrificed all his power to restart the shattered world.

Having completed his mission to save the world, he retreated into seclusion and peacefully enjoyed a simple life.

However, a video titled "Honkai Impact 3" unexpectedly revealed its past history.

Online, watching Ye Li fight alongside the Valkyries in the story, many people enviously commented, "Who is this guy?!"

As the plot unfolds, people suddenly discover that behind every seemingly perfect ending lies the silhouette of Ye Li burning his life away.

When the final chapter revealed the truth—that he sacrificed himself for the world, turning into dust in history—netizens shouted online in their loudest voices: "Live on, Yemen!!!"

Faced with the surging online tide and the emotional debts about to assail her, Ye Li, the person involved, only wants to say:

"Ai-chan, Amiros!"
