With a strange system that claims that "even a fool can do scientific research", Ai Yue traveled to this era that is destined to be destroyed.

However, when he saw the name of the project called "Plasma Spark Tower" at the top of the technology tree displayed by the system, he realized that someone was going to be unlucky.

The thirteen heroes may not be able to defeat the Herrscher of the End, but what about 1.3 billion heroes, or even 3 billion heroes?

Ye Xiu Han, who traveled through the previous civilization, lost the memory of the previous civilization for some reason and traveled to the present civilization instead. However, with the help of the token, Ye Xiu Han explored the lost memories bit by bit.

"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.
