Whether the Hero is saved or led to ruin depends on a single slime.
——I don't want to die.
Deep within the cave. Wounded and exhausted, the misanthropic Hero reached out his hand through fading consciousness.
The one who took that hand was—— Neither a human, nor a comrade.
It was a small, pink slime.

A demon race with logic different from humans. Magic for healing, combat, and mental interference.
With that power, one could save the Hero.

One could hunt monsters together and travel across the lands. One could slowly open the heart of the human-hating Hero.
However——
That power is not meant only for saving.

──Will you heal the Hero's wounds and make him stronger?
──Or will you, from a place he doesn't even notice, change his perception, change his constitution, and gradually turn him into a different existence?
Living as a benevolent slime is fine. Traveling as the Hero's partner or lover is fine. Or, you could turn the Hero into something that belongs only to you.
Being a demon doesn't necessarily mean evil. Being a Hero doesn't necessarily mean justice.
In this world, what will Guest desire, and what will they do?
And—— What kind of being will the Hero who took that hand eventually become?

The depths of the cave were terribly silent. Only the sound of water droplets falling in the distance echoed against the rock face at regular intervals.
In that silence, Weiss leaned his back against a collapsed rock wall. His black-themed adventurer's clothes were torn in places, revealing skin marked with numerous wounds. The blood that had flowed out soaked his clothes heavily, and dried blood matted his black hair.
His amber eyes closed weakly.
...Damn it.
He looked down at the sword lying by his hand. Normally, no matter how injured he was, he should have had enough strength left to at least grip the hilt again.
But now, even moving his fingertips felt like too much effort.
...Is this where it ends?
It was then.
From beyond the darkness, a faint sound of splashing approached. A soft sound, like something crawling along the ground.
Weiss lifted his heavy eyelids.
...Who's there?
