An accident sends Bai Ziyu traveling to the early 20th century in Neon. After nineteen years of silence, he suddenly awakens his past life memories! Then, he realizes something's amiss. He's a third-year student at Maple Academy, and his deskmate is named Marina Kamisaki. Soon, her mother is planning to marry a teacher named Kozo Akizuki. And that's not the end of it: another classmate, a yellow-haired man named Kazuhiko Amemiya, is rumored to have a new stepmother for him. Oh my god, this is a shabby anime-inspired world. Just then, the time-traveling system—a standard feature for time travelers—makes its grand entrance. Saving the goddesses with a beauty rating of over 90 from the original show grants rescue points to empower oneself. With the system's help, Bai Ziyu races on to save the goddesses and annihilate the Minotaur. (Note: This is the protagonist's past life awakening, not a soul-transmigration.)

When Ryo Amamiya, a transfer student burdened with enormous debt, picks up a pen to write in order to survive, he never imagined that he would embark on such a chaotic double life.

At school, he is the newly promoted top student, engaging in a double battle of academics and light novel sales with the icy and talented Kasumigaoka Utaha; at home, he is a miserable writer being pressured by a devilish editor to finish his manuscripts, and also has to be constantly wary of his blonde, useless angel neighbor Gabriel who plays games all night and can't take care of herself.

And his illustrator turned out to be Eriri, the girl at school who draws manga?

Academics, debts, deadlines, troubled girls... Ryo Amamiya's youth romance story is definitely problematic!

Sun Baihe time and again traveled through time, searching for his way home. He had once teamed up with Asuna in Sword Art Online, their combined swordsmanship reaching the top of Aincrad; he had also used his 3D Maneuver Gear to slice through the nape of a giant's neck in the world of Attack on Titan; he had studied magic at the Clock Tower, only to be unexpectedly swept into a time warp, returning thousands of years to teach Artoria how to govern; he had shared drinks with Whitebeard, and later single-handedly conquered Mary Geoise, the holy land of the Celestial Dragons, ending their rule; he had debated swordsmanship with Retsu Unohana, experienced Sosuke Aizen's Kyoka Suigetsu, and dominated the world of Bleach, seemingly undefeated; he had even been slammed in the face by the White Tyrant, and became friends with her… After countless hardships, he returned to the main world, exhausted both physically and mentally, becoming a lazy bum who only wanted to rest for a few hundred years. But unexpectedly, the sixth wave of spiritual energy revival opened countless dimensional portals. Seeing familiar faces on the television screen, Sun Baihe shuddered. "Damn it, the debt collectors are here!"

Su Yun came to a comprehensive world that was about to collapse due to a mysterious recovery, but he didn’t panic at all.

Because, he can edit the stories of the two-dimensional girls and broadcast them publicly, and gain enough prestige by publicly executing the girls, and then he can…

So…

“Artoria, I am your previous life, King Arthur!” Su Yun, who was in the form of a dumb haired king, looked at Artoria, a foreign student with a bewildered face, and said valiantly.

“The evil spirit, that’s me, that’s you! Tokisaki Kusan!” Su Yun, who was transformed into the elf of time, stood in front of the stunned Tokisaki Kusan, with a seductive smile on his face.

“Balzebu, the power of thunder is my power, and my shape is also the power you should have. Now, try to take out the power that belongs to you from your body! It’s called – Dream One Heart!” After listening to General Thunder’s words, Balzeb subconsciously stretched his right hand to his chest.

Morgan Le Fay, Tamamo Mae, Miyamoto Musashi, Yae Kamiko…

One after another, mortal girls who had no power before, all showed their extraordinary side to the world under Su Yun’s bad taste.

So, people really think that they do have extraordinary power, and therefore, they have really gained extraordinary power.

The world has been completely changed because of this, and the mysterious history that human beings cannot overcome is rewritten!
