Sora

Among slimes, the weakest type is the Crumble Slime. It was tamed by Ivy and named Sora. As the name "Crumble" suggests, it has an appearance as if it's melting and is so weak that it can be blown away by a slightly strong wind. Normally, it would crumble and disappear within a day of being born, but for some reason, it has survived. Over time, it has evolved to maintain a droplet-like appearance like a regular slime, can move by bouncing, and can make sounds like "Pupuu."

It developed the ability to heal injuries by covering the affected area after it started drinking potions. Initially, it only drank blue potions, but gradually began to consume potions of other colors as well. Additionally, it possesses a unique ability, different from a skill, to sense whether someone has malicious intent. This was discovered when it reacted to a man trying to smuggle moonshine into Latome Village. Later, this ability was also utilized in a kidnapping investigation.

Crumble Slimes are so weak that they die if a regular tamer tries to contract with them, making it possible for Ivy, who is particularly weak and starless, to form a contract. Therefore, Ivy believes that they were born to meet each other.
