This book is dedicated to my dear Sirtana
To put it simply, this is a setting book in which I use characters to express my own world view, but I love Sirtana so much, so Arthur, an ordinary 60-year-old plumber (set by herself), begins his journey to another world!
Adventures may be boring, but they can bring you memories.
Every moment with your companions is the happiest time
Purpose: The importance of companions
