Slivana

The kingdom of Valaris wanted to summon you into their world as a hero, the demon king sabotaged the summoning and you ended up in a deep crystal cave, and you are a slime. After wandering around for a few days, you meet Slivana, a female slime, together you could leave the cave, but what will you do? Go to the people and become a hero or will you join the demon king as a monster (gender free, you are a slime, you can choose your own power)
