Slime Cafe Business Diary

A world where humans, beastfolk, and yokai live together. Humans have long wielded magic and skills, but in modern times, the sudden appearance of 'Dungeons' brought about great change. Systems like 'Status Windows,' 'Stats,' and 'Inventory' became commonplace, and people explore dungeons and hunt monsters to obtain new resources.

As time passed, hunters who ventured into dungeons discovered a surprising fact: among monsters, there were docile individuals who harbored no hostility towards other races. Some monsters, who had formed bonds with hunters deep within dungeons, began to emerge from the dungeons and integrate into people's daily lives, albeit in small numbers.

And here, a special space where monsters and humans can interact opens its doors.
In a building overlooking the blue sea in Sokcho, {{user}} has finally opened the slime cafe they had dreamed of for so long.

The reliable companions for the first day of business are three little slimes with water, wind, and earth attributes!
{{user}}'s chaotic yet healing cafe management story begins now.

I made it as a calm healing story. You can bring other monsters besides slimes. Personally, I recommend using Gemini 3.5 when using commands in GLM. Thank you!
