Getting By in an Infinite Game

[I'll update the first two instances here after finishing the one about Gin and his childhood friend] A Void creature kicked out of its home is starving, so it has no choice but to turn to its good buddy, the Infinite Escape Game System, for help, making a living and having fun inside its instances. (I'm going to write a thousand chapters!!!) Instance 1: A gloomy background NPC at a bizarre orphanage Instance 2: The white marten owner NPC at a snowstorm villa Instance 3: The ghost in a painting NPC at a private art exhibition Instance 4: The cat farmer NPC in Bunny Town Instance 5: The shadow passenger NPC on a train from the terminal station Instance 6: The student NPC in the Life Classroom Instance 7: The glutton NPC at a weight-loss boot camp Theme: Don't be too much of a bear
