Honkai: Star Rail: I Became a Monster, and Firefly Hid Me on the Express

Yuan transmigrates into Honkai: Star Rail and becomes a terrifying, grotesque monster, as well as the “weekly boss” destined to be defeated by the protagonist's team in the next version.

To stay alive, he binds himself to the [Popularity Reversal System] and starts showing players in the real world exclusive tragic CGs, adding dramatic scenes like crazy.

In the story the players see, he was once a gentle bodyguard.

To save Firefly, he was willing to bear the scorn of the ages, forcibly absorbing endless toxins until he tragically degenerated into a mindless monster.

When the new version's PV is released, players across the internet break down in tears!

“HoYoverse, you have no heart! He turned into this for Firefly, and you make us deplete his HP?”

“I'd rather quit the game than fight this weekly boss! Anyone who dares hurt him can count me out!”

“Please, official team, give him a banner! I want to save him with E6S5!”

Meanwhile, in the game world.

As the Astral Express prepares to take down this “calamity monster,” Firefly, eyes red with tears, desperately stands in front of him to protect him.

In the end, to the disbelief of the entire universe, Firefly manages to secretly smuggle the fearsome monster back onto the train, holding him and crying every night.

Held tightly in Firefly's arms, Yuan can only shrug helplessly.

“We agreed this would be a nonhuman nightmare from the start. How did I become everyone's tragic what-if across the universe?”
