Ye You, a graduate of the Clock Tower Archaeology Department with a rare magical attribute, opened an antique bookstore in Tokyo. His favorite thing to do is to study knowledge in peace and tranquility. Until recently, he received a letter from his old friend, Tōsaka Tokiomi, who brought a little girl home. Then, strange things began to happen one after another. He heard vague whispers in his ears, and ancient images emerged in his mind. When Ye You gazed at the moon, he found that the moon was also gazing at him.

I'm a time traveler and a complete 2D otaku. My lifelong wish is to spend the rest of my life with a paper-faced wife, while also saying "no" to 3D women. Well, it seems half of my wish has come true. One day, I was pulled into a mysterious chat group. Glancing at the member list, I fell silent. [American Scythe]: Just blew up a building. If any jerk dares to say anything again, I'll be the next one to go. [Devil Kinniku Rin]: Damn it! I've spent all my gems this month! Anyone got a way to get some money? Urgent, waiting online! [Herrscher of the Rice]: Tonight's dinner is tempura, Kiana... Oh, sorry, I sent this to the wrong person. [Marin]: Ahhhh! Anyone got any new slimy girls? Such love! ...Looking at this group of friends, all with different styles, but all my wives from my past life, I fell into deep thought again. Wait, isn't this a "2D Beautiful Girls Chat Group"?

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.

General Thunder: "He saved Truth and set him on the path to eternity. With him by my side, eternity is not lonely. He told me that true love will last forever."

Ayaka Kamisato: "He is the new god of Inazuma, who saved Inazuma from fire and water. If you do not mind, Ayaka is willing to serve you for life."

Type-Moon world, the moon, Fate. Having traveled to the Einzbern family, Luo Zhen became the heir to the Third Law, known as the Son of Winter. So, let's just say he's the Son of Winter. It might be a bit childish, but a magus has to be childish! So he's meticulously planned, preparing to reign supreme in the magic world for generations to come. He's going to punch Tōsaka and step on Matou, and let that Mapo priest taste the pain of disembowelment himself—Fujimaru Ritsuka: "Second Master, I've found it!

Until that day, when the task lottery system was awakened... as long as you complete the task, you can enter the lottery.

So, in order to complete the mission...

Eula: You're telling me now that your confession is fake... I absolutely don't agree. You must be afraid of being rejected. Don't worry, my love, I will tell you my love...

Pots, pans, and utensils! Surrender to me!!

He arrived in the world of science with a crappy system that tricked Conan into mining right from the start.
