I'm Just a Frail Cup Cult Leader

Wu Sheng transmigrated while playing Cultist Simulator and, naturally, brought the game System along with him (not really).

Now, here's the question.

System: Here's a book of the Cult of the Cup. Go preach, cult leader!

Wu Sheng: I've only played the Cult of the Blade.

System (staring): The Cult of the Cup is the only book you can study, because I am that book.

Wu Sheng: .

Former cop-attacking maniac, current human heartbreaker, reminds you:

Please, all Mafia groups, curse users, cursed spirits, booze organizations, and the like, keep an eye on your combat assets so they don't get seduced by criminals...

P.S.:

1. Pairing undecided (but given Wu Sheng's tastes, it's probably Yuji)

2. Lighthearted tone. It won't have the heavy atmosphere of Cultist Simulator itself. The cult is just one of the toys in the game, and the content isn't complicated.

3. Tons of headcanon, both for the manga and the game. Lore enthusiasts, proceed with caution.
