I've traveled through time, but not just one world. When awake, I'm in the world of Souman, and when I'm asleep, I'm in the world of Harry Potter. But that's not the most outrageous thing. What's outrageous is the restraining power of the Souman world: Gaia, who enjoys picking up random things in the World Sea. To prevent the daily Souman world from being destroyed, Hanyu Genichi reluctantly picks up his wand and cleans up Gaia's mess. From the T-virus to Kabane, to ghouls, gastrula, and later, giants, they don't care about the lives of humans at all, do they? Gaia, you really only think about yourself.

Born in solitude, grow up among thorns.

Kanzaki Toru's life has long been filled with misfortunes: an abandoned child, a broken reconstituted family, a sick sister, and his hard work.

Finally, after quitting his irregular coding job, Kanzaki Toru used his talent to become a best-selling light novel writer.

He thought his life was finally on the path to stability - writing, going to school, and protecting his sister were all he lived for.

However, one day, God played a joke on him. A translucent panel like a game interface suddenly appeared in his field of vision, as if telling him that he was still loved by the world.

Kanzaki Toru: “…”

It issues quests, hands out rewards, and even grants him the ability to recreate entertainment from another world.

When he looked back one day——

He was already surrounded by girls with fiery gazes.

Their gazes became increasingly difficult to interpret, and their intentions gradually became clearer...

Although he had the "strategy system" in his hands, he was actually being "conquered" step by step in reality.

This is a heartwarming story about protection and redemption, and a lonely person surrounded by love.

The world view is integrated with "BanG Dream! It's MyGO!!!!!!", "Lonely Rock", "My Youth Romantic Comedy Is Wrong, As I Expected", "How to Raise a Boring Girlfriend", "The Quintessential Quintuplets", etc.

Tennoji Kaede enrolled in Advanced Nurturing High School and successfully awakened the Gray House Karma System!

The more you are tainted by the 'cause', the more 'effect' he will give back!

"Gray House, add some points!"

Afterwards, Tennoji Kaede was assigned to Class C and formed a partnership with Ryuen Sho.

From this moment on, the unbeatable King Class C was officially born!

......

"Ayanokoji Kiyotaka? The White House is just a masterpiece, but can you beat my Gray House's supreme martial arts?"

"Yamachi Haruki? The Black Room is the supreme masterpiece, but I, Tennoji Kaede, am willing to acknowledge you as the strongest underground!"

"Longyuan, please believe me, I have absolutely no intention of using you as a tool!"

"Besides my little angel Hiyori, are there no decent girls in the actual class?"

......

Time flies, and three years later, it's graduation time.

The ultimate strategy that Tennoji Kaede decided upon entering the university has been achieved!

He ultimately became a legend of practical education and high moral character...

Ritsu Haga, wearing the Tokyo World, gained the physique of a succubus, possessing a strong charm for female special attacks and super energy. Relying on a system that allows him to choose routes, Ritsu Haga quickly conquered the women around him and gained super powers such as time stop and hypnosis. But they were still not satisfied. Katsura Manami: This is just a massage. Saliva has a special effect on treatment, but saliva loses its activity immediately after leaving the mouth, so... Yukinoshita Haruno: If you like, I can bring my cute sister over too. Eriri: You can't ignore me anymore. I'm going to do everything I did with my mother! Looking at the increasing number of women around him, Ritsu Haga decided to run away first, otherwise even if he is a succubus, he can't stand it!

Suddenly, a beautiful silver-haired girl appeared before him. She said he'd awakened the ability to "slip," and she wanted to take him away and protect him. She also wanted him to transfer to Hoshi no Kai Academy. Wait, isn't this silver-haired girl Nao Tomori? Aren't there more than just Kaguya-sama: Love is War, Quintessential Quintuplets, and Charlotte here? ... Fortunately, he's no pushover. His abilities aren't limited to the one he got from "In Another World with My Smartphone"—slipping—but he also has abilities from "Cooking Master Boy" and "K"... (Are daily battles 50-50? Quintessential Quintuplets and Kaguya have everything. Conan's behind-the-scenes boss is exactly as some experts had guessed. I'm impressed!)

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!"

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.)

[Characters appearing include characters from Honkai Impact 3rd, Star Iron, Grand Blue, Oregairu, Kaguya-sama: Love Is War, and Saekano... as well as some heroines whose origins are unclear. I won't cite their sources; those who like these series will understand.]

Don't worry, it's not some cuckolded turtle.

Bai Li, who traveled through the fantasy world and practiced the ruthless way for four hundred years but still died under the heavenly calamity, gained enlightenment.

If I give him another chance to start over, he would be so ruthless that even a dog wouldn't be able to behave!

When he opened his eyes again, he actually came to a huge mess of anime world.

In this life, I just want to live a gentle and peaceful life like plants, but they keep coming.

……

Goto Ichiri: It was obviously me who came here first, whether it was to get to know Baili-san or to become friends with him...Nijiga, why did you?

Nagasaki Suyo: Is it bitter? It's over. Xiaoxiang, please don't contact me again. I'm afraid Bailijun will misunderstand.

Yukinoshita Haruno: You said you have a girlfriend? Does that mean the position of fiancée is vacant?
