Muchen traveled to the world of daily anime and lived there for seventeen years. During these years, he had been working hard to get married. But he found that since the world's first virtual game was released, the world seemed to have become wrong. Then...

I want to write a book. First, I need an interesting and handsome protagonist to connect with the reader. Then, one or two beautiful, lovely girls... maybe three or four would be nice too. With a boy and a girl, it's only natural to add some romance, some ambiguity, some heart-throbs, a layer of milk and honey, a touch of bitterness and astringency, all mixed together... It looks delicious. Then, add a flirty narrator and set it up as a system. Finally, to make the book taste even better, I need to add more sugar. I open the sugar jar, and then, with a slip of my hand, I pour the whole thing in... Damn, isn't that too sweet? I hurriedly pour in some more "Book of Songs," some Shura scenes, some life philosophy... Finally, this is the book... I think it tastes pretty good.

Lin Haoyu travels through time and space to become a villain in a book. When he completes his final role-playing task, he lands on his left foot first, so the system forces him to repeat the story. Unbeknownst to him, this time the heroine can actually hear his thoughts. [Holy crap! You actually agreed to be my girlfriend?] [What are you doing? Why are you throwing yourself at me? Where's your female dignity?] Lin Haoyu is stunned. Why are these heroines so off-kilter?

[Western Fantasy + Fusion Worldview + DND-like + Multiple Female Protagonists + Fighting Dust]

Elves, dwarves, halflings? Where does this come from?

Mage, priest, paladin? Supernatural powers? Interesting...

Spellcasting talent detected? Does that mean I can become a noble mage?

"No, buddy, what do you mean by assigned to the Geotechnical and Natural Sciences School?"

"Damn it! How come I'm assigned to civil engineering after arriving in another world?"

…

"Master Mage Gerudo, what do you think of the famous and legendary graduate of your magic academy?"

Many years later, when faced with an interview, the elderly magician remained silent for a long time.

"Nothing with a mage's soul!"

Flashing graves. Just after crossing over to a new world, it was destroyed, leaving Su Ye as its last human. Luckily, a chat group arrived, and upon signing in for the first time, he was given a 'Cocoon of the End', forever binding himself to this world. The stronger the civilization, the greater its power. But... there are no humans left in this world. So, my friends in the group, are you planning to immigrate? Free houses, land, and superpowers! You don't want the cursed child? Take it!

"Rehabilitation" is the journey starting from [The Fool] and ultimately reaching [The World]—a path of understanding the real world and forging an ideal one.

Ren Amamiya decides to complete his rehabilitation by "nine-timing."

Exploring Mementos with Hare, practicing swordsmanship with Mei, learning coffee brewing from Himeko, trading with Raven.

When Ren Amamiya confidently kicks open the deepest door of Mementos, bringing the invincible Satanael to challenge the final boss, the Evil God, he instead finds a white-haired, cold-faced man sitting on a throne eating instant noodles!

Suddenly looking back, seeing an extra white-haired Tuna among the partners who arrived with him at the Cocoon of Finality, Ren Amamiya has a sudden realization: he transmigrated to the wrong world! This isn't P5, but the world of Honkai Impact 3rd!

"Damn it, now I've really become the Trickster!"

Watching his companions, who deeply believe his "Persona" theory, shout things like "Kurikara!" and "Project Bunny!" as they charge forward, a drop of cold sweat slowly trickles down Ren Amamiya's forehead.

However, the most troublesome part is...

"Recently, Joker's room seems to have become quite the 'love nest,' hasn't it?"

After the battle, Bronya murmurs faintly, and nearby, Seele, Rita, Fu Hua, and the others instantly freeze up.
