Zenless Zone Zero, I'm Faking Amnesia, but I'm Actually a Void Hunter Big Shot

[Overpowered + Roleplaying + Fake Amnesia + Livestream Chat + Succubus Constitution + Multiple Heroines]

Lu Yingheng wakes up to find himself transported into the world of Zenless Zone Zero and, naturally, unlocks an incomplete system. After maxing out all the rewards he can milk from it, he has already become the Void Hunter known as the Dragon Emperor and believes he has no way to grow any stronger.

Then, during a chance rescue operation, he actually discovers another system user. After absorbing that system, he obtains the "Story Roleplaying System." He fakes his death to slip away, then joins the main cast as they steamroll everything in their path.

Vivian: "Yingheng, I've finally found you~"

Hoshimi Miyabi: "I knew Lord Dragon Emperor wouldn't die so easily."

Alice: "Big Brother Dragon Emperor... Father sent me to find you..."

(Romance will only appear in the slice-of-life segments, not in the main storyline, so the players won't know about the protagonist's romantic relationships.)

Player: "What? You're telling me that the cute guy I happened to rescue from a Hollow is actually Lord Dragon Emperor, one of the original Void Hunters who's survived to this day?"

"Then what else is there to say? I don't eat beef!"

(The early chapters lay the groundwork for the protagonist's life after faking his death. The main storyline begins in Volume 2, and Volume 3 covers the past.)
