Rui can't catch a break... Her life was turned on its head when she was transported to Roots, a world full of monsters, demons, and magic. Thankfully, she was able to awaken the powers of Sol within her and save that world from destruction! Alas, she had only just returned to her world after saving that one, and now monsters are attacking her town and kidnapping people!

Following the trail, she stumbles upon Tuberoth, a demon who only seems innocuous on the surface... He promptly traps her in a nightmare world made of illusions, a deadly game with her freedom at stake! Can she step up to the task and awaken from these terrible nightmares?

Trapped within Tuberoth's nightmare game world, Rui will have to clear all the doors in order to challenge the demon and break free of this hell.

She still has the magical powers of Sol on her side, but this illusory world has its own rules, and not all of them allow her to tap into her supernatural strength... To begin with, she can't attack Tuberoth at all! To make things worse, some of these pocket worlds can confound her mind, and even make her lose her memories!

Escape the nightmare, clear the cave of every single goblin you find... Only then will you be able to fight Tuberoth, the master of the dream, and escape back to your own world!

Different Doors, Different Worlds: While Tuberoth's hell dimension is smaller than usual thanks to Rui's magic powers, there are still a variety of different pocket worlds inside of it, each with its own gameplay system: Roguelite, Action, Visual Novel... Gather your wits and skills to master them all!

Gorgeous Animated Models: Enjoy animated models for all main characters! They will blush, rage, nod, and more as they talk and progress through the scenes. Dozens of emotions and poses bring their personality to life, creating unprecedented levels of immersion.

Branching Repeat Interactions：You'll spend a lot of time talking to characters and figuring out how to clear every door, and things won't always go well... Tuberoth has laid countless traps ahead of Rui, after all. But even failing and returning may open new branches for you! Whether to try them or not is up to you; it all depends on your desired outcome.
