Young Ivy, who retains some memories from her previous life, must confront a series of misfortunes in her new existence. After being reborn into an RPG-like realm, she finds herself in the weakest class and occupies the lowest rank. What's more, even her own parents distance themselves from her because she is a no-star Tamer. Ivy soon realizes that she has no choice but to rely on her own abilities to survive, so she scavenges for food and scraps left by others. However, her circumstances take a turn when she manages to tame Sora, an insignificant-looking slime who possesses an extraordinary quality that could benefit them both. With Ivy's care, Sora could become something special.
