"Shinji-kun!" "Yusuke-san, get to the point!" "Hmm... While the anomaly has indeed been resolved, wasn't the commotion a bit too much?" "Was it?" "It does seem quite normal for someone piloting an 80-meter-tall Unit-01 to beat up a 50-meter-tall monster." "Yasuhito-san, I'm a little annoyed by what you're saying. A gang fight against villains, isn't it just a matter of using whatever's available? But you guys need to get going! I can already see police lights flashing at the foot of the mountain. You'll be in big trouble if Inspector Yakushiji catches your eye. It looks like Special Vehicle Division 2 is here too." "Your way of putting it doesn't give me a very good feeling. Oh well. Let's go! Oh, by the way, here are this week's coupons! Remember to come to my shop!" "Oh! A stack of McDonald's coupons? That's a big help!" "So, shall we meet at Yukihira Restaurant later?" "Okay! I'll leave the cleanup to you. Where did Fujiwara-san park the car? We can't shake off those two policewomen without him." "I'll ride back on Eikichi-sensei's motorcycle first!" "Running away is not honorable at all!"

Yuuji Sakai, the usually vacant and somewhat weak protagonist, lives an ordinary life until the sudden appearance of a monster disrupts his ordinary life. Under the setting sun, Yuuji is suddenly attacked by an alien monster that transforms human "existence" into spiritual fire and then devours it.

At this time, a girl who called herself "Flame-haired and Burning-eyed Slayer" appeared and rescued Yuuji from the monster's mouth. Yuuji Sakai named her Shana based on the name of her large sword.

She told Yuji that his life was about to end - it turned out that outside this world, there was another world called the "Red World". In order to realize their ambitions, the people there took away the world's original power, the "power of existence", from humans one after another, and Yuji was one of the victims.

After the Crimson Apostle took away the "Power of Existence",...

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!"
