Lin Ye travels back in time to the start of his second year at Sobu High School, two years before the apocalypse. He decides to change the course of the apocalypse and save the world. As the apocalypse unfolds, the relationships between the girls around him become increasingly complicated. Shiyu: "Tell me, are you still in love with your first love." Yukino: "Tell me the truth, did anything happen with my sister?" Haruno: "Just once, let me be willful for once, after that, you should be with Yukino." Isshiki: "Senior, senior, I have been bought by you now, you have to be responsible!" Kato: "Lin Jun, I seem to know a lot of your secrets, and the pressure is a bit too much. Let me lean on you!"...

My journey is to endless anime! My ideal is to become a fighter among bulldozers! My goal is to have the most (untranslatable into human language) 2D harem! My code is that laws, morals, and species can no longer stop me! My boundaries are: freedom of will, evil is good, wings on board! PS: I basically solve everything with "bang bang bang" (roughly). PS2: Seriously remind you, the protagonist is basically not a good person~!

Izumi Masamune, an ordinary time traveler.

One day I unexpectedly discovered that my body had changed.

The ever-increasing physical strength, ever-improving charm, and the constant stream of heroines around him.

"I, Hikigaya, am a legendary agent, a leader in the association, a master of the mysteries, one of the Five Emperors of the Ocean, and the nemesis of the weird." "I have five cousins, a sister, a childhood sweetheart, two ex-girlfriends, a lovely junior, and a beautiful colleague, but no one likes me. I'm a complete loser." The everyday and the mysteries gradually intertwine, and despite our hesitation, we continue to move forward. Cthulhu has landed in New York, and the legendary agent Altria has disappeared... This era needs heroes. "...Stay sane, and follow me into madness." Hikigaya lit a cigarette expressionlessly, put on his sunglasses, and flashed his ID [White Robe Anzai]

Lin Zhi came to Chiba from Akita and lived in Aoyama Apartment.

etc!

What kind of monsters live here?!

A fallen angel from heaven, a girl with a side problem in the eyes of the evil king, a girl with a radiant appearance, a bald caped man who does it out of interest, an office worker who found a giant dragon, a girl who can't speak, a mother and daughter who like to draw 18+...

Lin Zhi's life became exciting.

The light music club leisurely drinking afternoon tea, the hardworking Muse, the blonde lady who also likes 18+, the absolutely correct Yukinoshita, and the friend with a suppressor on his head...

ps1: Involving characters from works such as "K-ON!", "A Silent Voice", "Love Live", "Borrower Girl", "Oregairu", "Gabriel", "Chuunibyou", "Maid Dragon", "Himuko Komekko", "Crayon Shin-chan", "Nonki no Nichiren", "Sakurasou", "Sword Art Online", etc.

Wu Shen thought he was destined to live a lonely life…

Until one day, he wakes up to find several girls appearing in front of him—each claiming to be his daughter from the future!

Wait—how did I suddenly become a dad?!

Huh? I think you’ve got the wrong guy...

What’s that? Your mom is Kasumigaoka Utaha?

You’re saying your mommy is Shiina Mashiro?

Your mother is Yukinoshita Yukino??

And your mom is Yakumo Yukari?!

And so, in order to save his adorable loli daughters from vanishing,

"How to Raise a Passerby Heroine" Megumi Kato "Stop hanging around me, why do you have such a high sense of presence just by making a movie!". Spencer Eri Sawamura "Can An Yilun get away as well? I will never be the loser this time!". Shiwa Kasumigaoka "The person who asked all high school students in Tokyo to come see my work must understand me very well."

"My Youth Love Story Really Has a Problem" Yukinoshita-san, can you please stop following me around all day long? What commission did that guy Sakurara give you? And Haruno-senpai, I really can’t do it!

Kasumigaoka Utaha: "Teacher Izumi, you are my woman, don't even think about running away!"

Kato Megumi: "Izumi-san is surrounded by so many beautiful girls. I'm a little unhappy~"

Yukinoshita Yukino: "Tell me the truth, do you like me or my sister?"

Yukinoshita Haruno: "As the eldest daughter of the Yukinoshita family and Yukino's sister, I shouldn't have such feelings, but I still want to tell you, Miss Qin Hai, I like you!"

Yuigahama Yui: "Izumi-san, do you think it's normal for a girl to like another girl? Actually, I'm... "

Isshi Iroha: "Senior~Senior~I am your little fan girl now, you must be responsible for me!"

Shiina Mashiro: "I suddenly realized that it's not just your paintings that I like. I also like you."

Sakurajima Mai: "What a cute little school girl that makes you want to love her."

The orange-colored aura is actually right next to me!!!"
