Persona: Saving Wakaba Isshiki

After transmigrating to the world of Persona, Lu Heng had planned to get into a good university without any fuss and settle into a quiet life, content with a modest fortune. But what did they mean, he was a Chosen Trickster destined to fight an evil god bent on destroying all of humanity? (The protagonist doesn't know the plot, there are multiple heroines, and this blurb doesn't do it justice. Please read the story.)
