Shinjiro was transported to the world of Bleach, becoming a human without spiritual power, unable to even defeat an ordinary Hollow. Fortunately, he obtained the [Life Simulation System], allowing him to experience the lives of different girls, change their life trajectories, increase their affection, and obtain rewards. He thought that since it was a simulated world, he could save girls but not take responsibility, and he was just a legend. But unexpectedly, one day, they all came knocking on his door? Rukia grabbed Shinjiro's collar, her little boots stomping on his chest, "Bastard! You've lied to me for so many years, and you think you can just walk away?" Retsu Unohana smiled and drew her sword: "How's your swordsmanship improving?" Rangiku Matsumoto squinted, "You used to say you only loved me, what's with these people now?" She glanced at Momo Hinamori, Soi Fon, and Ori Inoue behind her...

As a once-in-a-millennium genius of the Wu clan, Wu Yi originally thought he would follow family tradition and become a happy Kengan professional fighter after graduating from junior high school.

"Introduction: At the age of one, her prodigal father threatened to wean her, so she was forced to debut as a voice actor (voicing a crying baby).

At the age of two, because she was too cute, she was invited to star in various infant and toddler commercials, and became popular.

At the age of three,

she was the same as above.

At the age of four, she was the same as above. She became more and more cute, and her popularity continued to rise. At the age of five, she was the same as above... Holy shit, there are extraordinary people in this world?!

Meow meow meow? Where is the everyday style!

[A random female protagonist + a changing doll + a loser female protagonist + my little sister + ...]

The moment I close my eyes and open them again, a non-existent memory suddenly appears in my mind.

Rebirth or reincarnation?

Kazama Tetsuya doesn't want to think about those things right now. After his parents' divorce, he became self-destructive and had no source of income.

And those works that popped into my memory are completely absent in this world!

As a result, just three days after submitting the first volume of the light novel, there was a sudden knock on the door of Tetsuya Kazama's house.

Are editors these days so dedicated? They're actually going door-to-door to sign contracts?

Chat group routine ↓

[Useless Angel Gabriel]: You dog group owner, how about I touch your foot in exchange for a thousand points?

[Lin Ye]: Touch me all night!

[Snow Cat Yukino]: The dog group owner is up to his old tricks again. Why don't you watch my cat do a backflip?

[Foodie May]: Group owner, the sisters are all waiting for you to come and tutor them. Remember to bring meat buns!

[Dragon Fights Tiger Star Bear]: Hahaha, when will the group leader come here for drinks again? Chen Tiantian is talking about you.

Tokyo. Inside an apartment. A handsome young man stood silently before the bathroom mirror. Not long ago, inexplicable memories flooded back. Now, he had completely absorbed them, realizing he was no longer in the same world. There were no more dump trucks, no more divine favor.

[Multiple female leads + crossover anime + apocalypse + raising/raising a child + otherworld]

Good news, we've traveled through time!

Bad news, it's the end of the world.

Good news, I have my own system.

The bad news is, it's a dating system.

"You want me to fall in love in a world where a packet of instant noodles can do anything? Is it that your communication skills are flawed, or is it that my comprehension skills are flawed?"

This is the story of an ordinary person who transmigrates to a post-apocalyptic Japan, only to acquire a uniquely styled romance system, and incidentally, slay some Japanese devils.
