Honkai: Star Rail: The Evil God Girl's Agent of Faith

(A touch of Lovecraftian elements + life in game instances + a love polygon later on)

Employed by the Evil God-chan, Lu Zhang is often sent to carry out nearly impossible missions. His one and only goal: spread faith in the Evil God throughout the world.

This time is no exception. He transmigrates into the world of Honkai: Star Rail, a game instance with an extremely high difficulty level.

He uses his wisdom to measure the nonexistent vast territory of the Glamoth Empire, clear the skies, and rescue the entropy-loss magical girl Iron Cavalry from peril;

With fiery passion and years of careful planning, he crushes the third Alliance of the Denizens of Abundance threatening Fanghu. Beneath the appearance of the Reignbow Arbiter, he rescues his mentor, who would go on to become his future diviner. The whole world is left in shock;

The restrictions of Erudition cannot sever his connection with the girl with the pointy hat. The two become as close as teacher and student, composing the perfect sequence together and breaking through the restrictions with "prediction";

Wherever Lu Zhang goes, faith in the Evil God spreads.

And so does romantic trouble.

"Now I'm curious what it will be like when you see them again."

"You... You were the one who told me that pursuing them would make spreading faith a lot easier!"

"Well~ that's what you get for taking the easy way out."
