The Shut-In Prince’s Splendid Social Debut — Me, a Villainous Imperial, Have Spent the Last Fifteen Years Fighting the “Wicked Thoughts” Eating Away at My Mind. When I Finally Returned to High Society, There Were Way Too Many People I Didn’t Recognize —

A certain man who dies from a government-designated incurable disease is reincarnated into the world of a multi-ending RPG—as a villainous imperial noble.

The body he reincarnates into is Yoan Joachim Rodenze, the Third Imperial Prince of the Rodenze Empire.

Careless, arrogant, and brazen to the core, Yoan is a notorious villain who commits every atrocity imaginable, only to meet a shocking end by drinking a poisoned cup.

For certain reasons, Yoan is forced to become a “shut-in prince,” and after fifteen long years, he finally—belatedly—makes his debut into high society.

Naturally, Yoan’s faction is utterly run-down, so deserted that even the sound of cicadas echoes through it.

He doesn’t want to be assassinated, so he has no intention of becoming emperor.
That said, he still wants to build his faction up to a respectable size.

This is the story of how, after breaking free from his shut-in life and acting aggressively, people with misty eyes begin appearing one after another.
