Hello everyone~! I'm Saori from Otaku Republic!

This time! Could it be...... the worlds are actually connected!? These three trending RPGs are gaining attention in Japan right now! Let’s quickly check out what they’re about!
【Limbus Company】Are the Worlds Actually Connected!? A Trending RPG Series Gaining Popularity in Japan! Limbus Company, Library Of Ruina, and Lobotomy Corporation

Connected through eerie worlds! How exactly are Limbus Company, Library Of Ruina, and Lobotomy Corporation—growing in popularity in Japan—connected?


Are you familiar with these three titles? All of them starting with the letter 'L' feels like fate...... Here's a quick breakdown of each game!
Limbus Company

The genre is a “Sin Resonance Brutal RPG.”
Released in 2023 as a mobile and Windows 10 app game for iOS, Android, and PC.

The protagonist, whose head has been turned into a clock, is taken in by the Limbus Company and told that by completing missions, they can recover their memories and original head.
The mission: together with 12 prisoners, roam a world overrun by monsters and collect the “Golden Boughs”......!

Library Of Ruina

The genre is a library battle simulation game.
Released in 2021 on various platforms including Nintendo Switch.

The player becomes the head librarian of a certain library.
They engage in battles, known as “receptions,” with those who receive an “invitation.” If they win, the opponent is turned into a book, bringing them closer to obtaining the “one book that records everything.”
As the head librarian, the player conducts receptions, controls allied librarians to collect various books, and aims for victory.
Lobotomy Corporation

The beginning of it all.
Released in 2018 as a PC game.
The genre is a horror strategy management simulation game.

The player becomes a new manager at Lobotomy Corporation, a company that extracts energy from mysterious entities called “Abnormalities” through specific actions.

To meet daily quotas, the protagonist, as the manager, instructs subordinates on which Abnormalities to take care of.
Abnormalities are entities that strongly interfere with the mind, and if emotionally unstable staff are sent to handle them......


From my personal impression, I remember a time when Lobotomy Corporation was a huge topic in Japan! Back then, before updates, the character graphics were much simpler, and didn’t have such distinctive visuals.So I think those who discovered Lobotomy Corporation learned that its sequels inherited and connected to the same world, leading more people to check out Library Of Ruina and Limbus Company as well.


All three of these games are horror-themed and slightly eerie simulation games! If you've played one of them, definitely try the others too!
