[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!

Kazama Tetsuya went completely mad, determined to use the works from his memories to make money and support his family, resulting in: "Saekano: How to Raise a Boring Girlfriend", "My Youth Romantic Comedy Is Wrong As Expected"...

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.

[Borrowing Girlfriend + Quintessential Quintuplets + Spring Objects + Dressing Dolls + A Silent Voice…tentative]

Yuta Kijima accidentally traveled to an island country. His previous life was not a highlight, but in this life, with the proficiency system, he must make himself live more freely.

I didn't expect that not long after I traveled through time, I unexpectedly fell in love with a Sakura girl online. I had planned not to care about the illusory online relationship, but I didn't expect that my online love object would be Kato Megumi, the considerate Kato Megumi, the tsundere Eriri, and the fat senior sister Kasumi wearing black stockings.

In the days that followed, all kinds of romantic luck continued to appear around him.

"I'll always love Kato Megumi!" "Eriri is the best in the world!"
