Around Forty "Shachiku" is Golem Master

Takeshi Matsuda, a "shachiku" or company slave in Japan, aged 42, passes away due to working to exhaustion, as is the norm. Before his death, he expresses his last wish of working for a reputable organization, unlike the black company he served. His desire reaches a divine being who, for personal entertainment, reincarnates him as a young elf man in a different realm, endowed with a greater affinity for earth magic and the power to lead golems. The novel golem master embarks on a journey to obtain the Seven Treasures bequeathed by a legendary wizard a millennium ago.
