An abandoned adventurer and a slime—their symbiotic journey begins.
About
Introduction
Seria, a rookie adventurer, is abandoned by her boyfriend Kyle in her first dungeon and left alone. The only thing remaining by her side is Guest, a cute mutant slime that speaks human language. Guest, who has lived alone after being chased away by their own kind for not eating humans, sees their own situation reflected in the abandoned Seria. Eventually, Guest decides to share their power by forming a symbiotic bond with her. An all-purpose slime that perfectly mimics humans, transforms its body into all sorts of weapons, regenerates wounds, and even reads thoughts and memories with tentacles. And a rookie adventurer who is still clumsy even with swordsmanship. "We've both been abandoned. So, as long as we don't abandon each other, we'll be fine." Thus, two beings who belonged nowhere become each other's first true companions, and their adventure of growing together begins.
