Losing Interest in the Otherworld Hobby

One day, a middle-aged man wandered into another world.
For some reason, that world, colored with magic and levels, was kind to him.
Using the power he had gained without effort, he embarked on a journey of pleasure that he could not do in his original world.
The man’s self-indulgence has a profound effect on those involved.
The man’s whims and fancies cause ripples in different societies.
But the man does not care about it. ……
The —- freewheeling journey continues.
Until the day the man grows tired of his otherworldly pastimes.
